Washington Fish and Wildlife Commission are currently reviewing existing size limits, bag limits, and fishing season for cabezon in Puget Sound waters. Cabezon are bottomfish that inhabit rocky areas. They can measure up to 30-inches and weigh up to 25 pounds. REEF data from the Puget Sound, representing 11,646 individual survey from 427 sites throughout the region, were used as part of the Commission's review to identify trends in cabezon abundance in Puget Sound. WDFW researcher, Dayv Lowry, conducted the analysis. According to the REEF data, there is a decreasing trend in the frequency of detection of cabezon between 1998 and 2012. This trend is most pronounced in the central Sound from Seattle to Tacoma. The majority (81%) of cabezon sightings in the REEF database are from Edmonds Underwater Park, a long-time marine reserve north of Seattle. At Edmonds, cabezon appear to have decreased sharply since 1998. These findings were included in a report submitted the Commission (report available online here). Earlier this year, the Commission voted to reduce the daily catch limit of cabezon to one fish and prohibit the retention of cabezon measuring less than 18 inches in length. They are currently reviewing the fishing season length and are meeting in June.
REEF members are at the heart of our grassroots marine conservation programs. Over 50,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Mike Delaney, one of REEF's earliest Pacific Northwest volunteers. Mike has been a REEF member since 1999, and has conducted 433 surveys. He is a member of the PAC Advanced Assessment Team, and he has the distinction of conducting the 20,000th REEF survey in the Pacific region back in 2011 (see story). Here's what Mike had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member? How did you first hear about REEF?
I heard about REEF through the Living Oceans Society’s Living Reef Project. I began my training course with Susan Francis and Dana Haggarty in 1999 and I was part of the LOS’s pilot PNW Invertebrate Survey Project. To improve my identification skills of PNW species, I was mentored by Donna Gibbs and Andy Lamb of the Vancouver Aquarium. In an effort to gain more buddies to survey with, I began organizing Great Annual Fish Counts and teaching the REEF curriculum. Fish watching, conducting surveys, and REEF became a passion.
If you have been on a REEF Field Survey, where and what was your trip highlight?
I had the opportunity to visit one of my favorite dive destinations Hornby Island and take part in the 2012 Field Survey lead by Janna Nichols and hosted by Hornby Island Diving . I have been to Hornby Island numerous times, and it is always a treat because it offers a great variety of marine life. During the trip, the group was able to dive a site that is not visited frequently and was inhabited by large schools of rockfish, lingcod, cabezon and colourful invertebrate life that adorns the sandstone walls. Another great thing about REEF is the ability to learn and survey in other regions, whether it is a REEF trip or not. I have had the opportunity to complete surveys in the TWA and in the TEP!
In your opinion, what is the most important aspect of REEF’s projects and programs?
The concept of scuba divers as citizen scientists is inspiring. As an individual we can contribute to a greater good: the understanding of the ocean and its inhabitants! As ocean explorers we can collect data and know that the information collected is being used to support science initiatives to protect the oceans.
Do you dive close to where you live, and if so, what is the best part about diving there?
In Vancouver we are fortunate to have numerous local dive sites to visit and most of my surveys are completed in the rich emerald waters of British Columbia. One of my frequented dive sites is Whytecliff Park and I had the unexpected surprise of completing the 20.000th PNW survey at the same site in which I conducted my very first REEF survey! Whytecliff is a great site because you never know what critters you might come across. Whytecliff Park offers wall diving with lots of sponges and a sandy bay with eel grass beds for poking around on your safety stop.
Do you have a favorite local (or not) REEF field station or dive shop?
In 2006 I began working at The Edge Diving Centre, which was quickly registered as a REEF Field Station, one of the first in British Columbia! I have been able to introduce numerous new divers to the REEF survey project!
What is your favorite fish or marine invertebrate? Why is it your favorite?
I have an affinity for our local PNW Rockfish! Ray Troll’s Rockfish poster adorns my wall as a tribute to my love of rockfish. Discovering something out of the ordinary always gets me excited. In 2008, I spotted a lone Black Rockfish at Whitecliff Park, which is notable because Black Rockfish have just about all been extirpated from Howe Sound. In 2009, also at Whytecliff Park, I confirmed a Blue Rockfish sighting, a species known mostly only from the outer coast. Sharks are my an all time favorite! I had the chance to visit and survey the Socorro Islands with it’s great number of shark species that inhabit the islands. Always awesome to dive with big sharks!

REEF has just completed our final assessment report for our five-year Wellwood Restoration Site monitoring project. Before I share some results from our study, let me give you a little background information and please visit our website to view our full report http://www.reef.org/programs/monitoring/wellwood. The M/V Wellwood, a 122-meter Cypriot-registered freighter, ran aground on August 4, 1984, on Molasses Reef off Key Largo, Florida, part of the Florida Keys National Marine Sanctuary (FKNMS). The ship impacted the reef’s upper fore reef and subsequently remained aground for 12 days. The grounding destroyed 1,285 square meters of living coral reef and injured 644 square meters of coral reef framework. Prior to the grounding, the area was a transition zone with high relief coral formations. The grounding transformed the area into a flattened, barren pavement covered with coral rubble.
The study area of this project included a portion of the grounding area that is being restored and two adjacent reference sites. The Restoration site surveyed included restoration modules and contiguous low profile hardbottom areas adjacent to and in between the restoration modules. Nearby high profile reef, ledges, and undamaged/unrestored reef were not included as part of the Restoration Site. A north and south undamaged reef area were both used as two control sites to compare fish sighting data between the Restoration area and the natural (control) reefs.
REEF’s study focused on fish assemblages and not the coral and invertebrate communities. A team of Advanced Assessment Team REEF Experts conducted Roving Diver Technique (RDT) surveys in addition to belt transect surveys on the Wellwood restoration site and two adjacent natural reef sites seven times during Year 1. The team visited the sites once prior to restoration (May 2002) and 13 times after restoration was completed, monthly for the first three months, quarterly for the following year and semi-annually thereafter. An average of 12 surveys of each survey type was conducted during each survey effort. While REEF surveyors used the RDT surveys to collect sighting frequency and abundance data on fishes over all three reef areas, the belt-transect method was used to collect density and biomass data on fish taxa. These two methods used together give us a snapshot of how the restoration site is recovering in terms of fish assemblages as compared to the two non-impacted, adjacent reef areas.
Obviously, the most notable observation a diver makes when diving on the Restoration site is one of just how long it takes coral reefs to recover after devastating ship impacts. The Restoration site shows little resemblance to the surrounding non-impacted reef sites. The areas surrounding the Restoration site are high relief reef areas dominated by reef building corals with some very old colonies of Star coral (Monastrea annularis) and Elkhorn coral (Acropora palmata), old to the tune of thousands, not hundreds of years old. Age is important here since it takes a long time for coral colonies to rebuild structure and relief that attract different fishes over time. The smaller overall fish populations and absence of many species of fish on the damaged site are both conspicuous and the lack of coral structure makes it easy to destinguish the Restoration area from the surrounding reefs even 23 years after the initial ship grounding. However, there are signs that fishes are very slowly recruiting onto the Restoration site.
During the monitoring period (2002 - 2007), a total of 165 species were recorded at the Restoration site, 189 species at the North reference site and 207 species at the South reference site. The Restoration site recovery is clearly aided by the addition of restoration modules (2002), increasing the amount of available habitat suitable for reef fish communities, think vertical habitat here, and recessed areas underneath these modules for fish to shelter. At the Wellwood grounding site, the overall fish diversity as well as density and biomass of most key fish families continue to be less than that of the two nearby, non-impacted reefs that were selected as monitoring reference sites. Parrotfish and surgeonfish appear to be responding the quickest to the restoration efforts, grazing along a recovering hard coral landscape currently dominated by soft corals (Gorgonians). Nearly absent today on the damaged area are sightings of grunts and snappers, both of which are seen in high frequency and abundance on surrounding reef sites with plenty of relief for them to take cover. Residency of fish, movement patterns and habitat usage are all important indicators of reef recovery. So are linking coral, invertebrate, and fish studies to see a more complete picture of how the Restoration site is improving. There are signs outside of the slowly improving trends the data show such as a little Redspotted hawkfish that has taken residence on one of the modules with lots of Ken's Staghorn coral affixed.
Many more studies are necessary to properly evaluate recovery dynamics for reefs and since most reef recoveries worldwide are hampered by other anthropogenic impacts such as overfishing, excessive nutrient loading from human pollutants, and global warming stresses, these case studies are critically important in developing mitigation strategies for damaged reefs. For the full report on our Wellwood findings, please visit our website http://www.reef.org/programs/monitoring/wellwood. REEF would like to thank the many individual REEF members who dived on this project over the past 5 years, as well as Quiesscence Dive Shop in Key Largo for dive support, and Ken Nedimyer for photos and his ongoing coral replenishment work. And finally, our thanks to the Florida Keys National Marine Sanctuary for contracting REEF for this project. We hope that this work will continue in order to monitor the long term changes in fish assemblages on the Restoration site.
The idea of an annual fish monitoring came over 25 year ago, with the first official Great American Fish Count (GAFC) in 1992. Dr. Gary Davis led the Channel Islands National Park effort as way to encourage sport divers to report fish sightings. The small number of marine scientists, the immensity of the oceans and the scarcity of funding required that volunteers be trained to assist with a nation-wide fish monitoring effort.
The use of volunteers to monitor animal species has proven to be extremely successful. The GAFC was modeled after the Audubon Christmas Bird Count, which continues to play a significant role in documenting and raising awareness of the declining populations of migratory birds, and has helped reduce destruction of their habitat.
The first GAFC event was held at Anacapa Island, California with fifty participants. The event was focused during the first two weeks of July to attempt to capture as many divers as possible and attract media attention. The Channel Islands National Marine Sanctuary joined in 1994. By 1995, the GAFC had become a coordinated effort between the Channel Islands National Marine Sanctuary and Monterey Bay National Marine Sanctuary. The ultimate goal of the GAFC was to have divers become interested enough in fish monitoring to map and adopt sites that could then be visited year-round.
The National Oceanic Atmospheric Administration (NOAA) National Marine Sanctuary Program expressed interest in the GAFC and Reef Environmental Education Foundation (REEF) working together to support and promote volunteer fish monitoring throughout the entire Sanctuary program. By the end of 1997, the GAFC evolved into a national event held during July of each year coordinated by American Oceans Campaign, REEF, and NOAA's National Marine Sanctuary Program. By 1999, REEF became the sole organizer of the GAFC with continued partnership with and NOAA's National Marine Sanctuary Program.
In 2001, a full-time dedicated staff was hired to managed the logistics and planning of the GAFC thanks to the Curtis & Edith Munson Foundation, the National Fish & Wildlife Foundation and PADI Project Aware. The 2001 event was a huge success. The number of seminars quadrupled and many dives were conducted throughout the nation, Canada, and in the Caribbean. Many GAFC dives were conducted within National Marine Sanctuaries, such as Florida Keys, Gray's Reef, Stellwagen Bank, Flower Garden Banks, Monterey, Channel Islands, and Hawaii. Approximately 900 people participated and over 1,900 surveys were conducted during the July event that year.
Due to the increased participation and overwhelming response and commitment from REEF's Survey Project regions throughout the Caribbean, Gulf of California, and British Columbia, in 2002, the Great American Fish Count officially changed its name to the Great Annual Fish Count.
Today, REEF is the sole coordinator for the event which continues to grow and brings in approximately 2,000 marine life surveys in the month of July alone. These efforts reach hundreds of volunteers throughout REEF's survey regions in dozens of countries. 17th GAFC this year in 2008 is sure to be a great one - get involved!
While every one of REEF’s 10,000+ volunteers who have conducted a survey as part of the Volunteer Survey Project are Making Dives That Count, there is a small cadre of surveyors who have taken their passion for fish and critter watching to the next level. They are the volunteers, those most active in each of REEF’s project regions, who have actively strived to move through the REEF Experience Level system, often becoming REEF Experts and members of the Advanced Assessment Team (AAT). And among this group, there are a handful of surveyors who have reached a significant benchmark – the 1,000 survey mark! Passing this benchmark gets you a place in the REEF Golden Hamlet Club. And this Summer, REEF welcomes two new GHC members - Bruce Purdy and Dave Grenda. They join Peter Leahy, Linda Baker, Lad Akins, Judie Clee, Linda Ridley, and Linda Schillinger.
Bruce Purdy is the owner/operator of the Bahamas diving liveaboards Aquacat, Cat Ppalu and Blackbeard's Cruises. He's been a REEF member since 1994 and a member of REEF's Tropical Western Atlantic AAT since 2002. Bruce is a staunch conservationist and has been integral in supporting REEF's lionfish work in the Bahamas. In addition to his work with REEF assessments and lionfish projects, he has also pioneered sea urchin restoration efforts in the Bahamas. Even though he has reached the milestone of 1,000 surveys, Bruce continues to encourage his diver to join him in surveying Bahamian reefs and supporting REEF's conservation projects - Way to go Bruce!!!
Dave Grenda has been a REEF member since 1998, and is one of the very few of our volunteers who have conducted REEF surveys in all four regions -- Tropical Western Atlantic, Tropical Eastern Pacific, West Cost of the US, and Hawaii! He joined the Tropical Western Atlantic AAT in 2001 and has participated in multiple AAT special projects. Dave is also a NOAA Science Diver and has participated in multiple NOAA research cruises in National Marine Sanctuaries. Most recently, Dave started helping with the REEF Grouper Moon Project and just returned from a few weeks on Grand Cayman helping to tag Nassau grouper. His passion for fishwatching shines through on projects and he is always eager to share the joy of a new find. In his "other" life, Dave is a retired Air Force Colonel. Way to go Dave!!!
After many years of planning, financial woes and last minute negotiations, it appears that the Hoyt S Vandenberg, a 520-foot troop transport/missile tracking military vessel, will be sunk as the newest artificial reef in the Florida Keys. Recent communication with the State of Florida’s Fish and Wildlife Commission has given the go ahead for REEF to initiate pre-deployment monitoring of the sinking site and 7 other adjacent reef areas to study the recruitment and movement of fish around the wreck and reef sites.
The one year study will also include surveys of non-native orange cup coral, titan acorn barnacle and Indo-Pacific lionfish. While exact dates have not been set for the sinking, plans are for the ship, located now in Virginia to be towed to Key West in early April and then scuttled 6 miles offshore in May. REEF Advanced Assessment Teams will survey the sites prior to deployment, then again one month following the sinking and quarterly through the remainder of year one. It is anticipated that the wreck will provide significant habitat for fish as well as additional recreational opportunities for fishing and diving activities. Data gathered during REEF’s efforts will aid in determining how effective the ship is in meeting its biological objectives.
For more information on the Vandenberg fish survey project, contact Lad Akins, Lad@reef.org (305) 852-0030.
One of the best parts about fishwatching is that no matter how many surveys you have under your belt, there's always a chance to see something unexpected. Recently I was diving on Davey Crocker Reef near Tavernier in the Florida Keys with four REEF surveyors. As often happens, we got separated, me with my photography and the others surveying. I spotted a brown fish about 8 inches long “drifting” in the water just under a ledge overhang. It sort of looked like a croaker to me, but not one that I recognized. I photographed it from a distance and continued to photograph while moving closer. The fish remained still, just looking at me. Finally, when I got about 6 feet away it retreated into the gloom under the ledge.
Back on the boat we were talking fish -- as usual. One of the others commented about a strange brown fish she had seen under a ledge. It turns out everyone had seen it and no one knew what it was. The entire group were members of REEF's Advanced Assessment Team (AAT, Expert Surveyors), so no one knowing is surprising. After downloading my photos, I researched the mystery fish. My hunch was correct; it was a Croaker, a rarely seen Blue Croaker, Bairdiella batabana. These were the first sightings of this species to go into the REEF database!
So how do you know if it's a Blue Croaker? The body coloration can be copperish to bluish brown. The only distinctive marking is a white crease on the gill cover.
REEF is proud to release the latest version in our series of instructional marine life identification courses – Fishwatching in California. The California curriculum consists of three courses on one CD – divided into Southern California, Channel Islands, and Central/Northern California. Pictures and text are included and are geared for anyone interested in teaching Fish ID – ideal for dive shops and instructors, dive clubs, marine science centers and aquariums, and other groups. This course completes the library of West Coast curricula: California Fish ID, California Invertebrates and Algae, Pacific Northwest Fish, and Pacific Northwest Invertebrates. We would like to thank all of the photographers who generously donated underwater images for these courses!
These instructor-led courses are a great way to introduce divers and snorkelers to the variety of marine life that can be seen during their time in the water. Each module contains a CD-ROM with images with an easy-to-use teaching curriculum to train students in identification and REEF survey methodology. A sample starter kit is also included. Courses can be taught in approximately 2-3 hours and cover 50-70 of the most common species for an area.
