BLUE HERON BRIDGE SHORE DIVE at PHIL FOSTER STATE PARK, RIVIERA BEACH FL
Road trip to Blue Heron Bridge for a Shore Dive to find unusual critters: batfish, fly gurnards, sea horses, frogfish, jawfish.....
This is a 1 tank 90-120 minute shallow shore dive (<25 ft).
ENTER WATER 60-90 MINUTES BEFORE SLACK HIGH TIDE (1:33 pm on 11/14)
Carlos & I will be at BHB by 11:30 am to give an orientation. We will enter the water by 12 pm.
Attempt a 2 hour, 100 Fish ID dive, or do 2 tanks or snorkel on Alligator Ledge. Alligator Ledge has a high diversity of fish species and a huge abundance of each species. You have to push the fish out of the way to see the reef :) This is a shallow reef in 12-28 ft of water.
Managing natural populations and communities requires detailed information regarding demographic processes (or status of a population) at large spatial and temporal scales. This combination is challenging for both traditional scientific surveys, which often operate at localized scales, and citizen science designs, which often provide data with few auxiliary information (i.e. no information about individual age or condition).
The authors of this study (including REEF staff Lad Akins) examined the recent case of Indo-Pacific lionfish invading Northern Gulf of Mexico coastal waters. The authors compared traditional reef fish monitoring efforts to less traditional data including the observations of divers through REEF's Volunteer Fish Survey Project and spearfishers. They found that citizen observations documented lionfish 1-2 years earlier and more frequently than the more traditional monitoring efforts.
This paper presents results from a study conducted as part of REEF's Grouper Moon Project, evaluating the potential ecosystem-level effect of Nassau Grouper aggregations. In particular, the study looked at the impact the spawning aggregation has in creating biogeochemical "hot moments", which occur when a temporary increase in availability of one or more limiting nutrients results in elevated rates of biogeochemical reactions.
A new scientific paper that features research from REEF's Grouper Moon Project, "Hot Moments in Spawning Aggregations", was recently published in the journal, Coral Reefs. The study looked at the impact of a Nassau Grouper spawning aggregation in creating biogeochemical "hot moments", which occur when a temporary increase in one or more limiting nutrients results in elevated rates of biogeochemical reactions.
In 2006, researchers from Univeristy of North Carolina Willmington collaborated with Grouper Moon Project researchers from REEF and Cayman Island Department of Environment to conduct mobile hydroacoustic surveys on the Little Cayman spawning aggregation site. Hydroacoustics, which is similar to a fish finder device found on a recreational fishing boat, but with better resolution and technology, has emerged as a valuable tool in fishery population assessments.
At the break of dawn on September 13th, 79 skilled lionfish hunters set out to compete in the Fifth Annual Key Largo Lionfish Derby. Vying for more than $3,000 in cash prizes, 22 participating teams brought in 573 lionfish to the John Pennekamp Coral Reef State Park during this sunrise to 5:00 pm event. Team We’re No. 2 took 1st place for most lionfish with an impressive 154 lionfish.
Despite uncertainties surrounding the population status of the protected Atlantic Goliath Grouper’s, fishery managers are under pressure to end the harvest moratorium in place since 1990. This study sought to measure the proportion of anglers interested in reopening the goliath grouper fishery and to identify key reasons for this interest. The authors also estimated the amount that anglers would be willing to pay for a Goliath Grouper harvest tag (the right sold to an angler to harvest one goliath grouper).
This paper reviewed the population status of Atlantic goliath grouper, Epinephelus itajara, in coastal waters of the southeastern United States. The study is based on quantitative surveys conducted by the authors and the Florida Fish and Wildlife Conservation Commission’s Artificial Reef Program (n = 505), coupled with data submitted by REEF surveyors (n = 27,542) over 15+ yrs.
