Lad Akins, REEF Director of Special Projects, recently co-authored a paper summarizing work documenting feeding patterns of lionfish in the Bahamas. Understanding the predation behavior of this invasive species is important to be able to predict and mitigate the effects of Indo-Pacific lionfish (Pterois volitans) on Caribbean fish communities. Lad and his colleagues at Simon Frasier University studied the activity levels and prey consumption rates of lionfish on 12 shallow coral reefs in the Bahamas in relation to time of day and prey availability.
REEF Field Surveys are a great introduction to fish identification for novice fishwatchers, and are a fun way for experienced surveyors to build their life list while interacting with fellow fishwatchers. REEF staff, board members, and other REEF instructors lead these trips, and each features daily classroom seminars and a full diving schedule. Don't miss out, spaces are filling up for our 2012 trips. The schedule and more details are posted online at www.REEF.org/trips.
REEF members are at the heart of our grassroots marine conservation programs. Over 43,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Sally Davies (REEF member since 2004) and her sister Helen Davies (REEF member since 2006). Collectively they have conducted 100 surveys, and both participated in the recent inaugural South Pacific REEF Trip (more on that next month!). Here's what Helen had to say about REEF:
Every month, scientists, government agencies, and other groups request raw data from REEF’s Fish Survey Project database. Here is a sampling of who has asked for REEF data recently and what they are using it for:
- NOAA scientists from the Protected Resources Division are using data on three species of endangered rockfish to evaluate their status in the Salish Sea.
-University of Washington scientists are using REEF data on invasive tunicates to map distribution of the species throughout the Pacific Northwest.
REEF is proud to partner with over 130 dive shops, dive clubs, individuals, and other organizations as REEF Field Stations.
Predicting and mitigating the effects of invasive Indo-Pacific lionfish Pterois volitans on Caribbean fish communities requires a thorough understanding of the species’ predation behaviour in the invaded range, including the types and amounts of prey consumed and how foraging patterns vary in relation to extrinsic conditions. We studied the activity levels and prey consumption rates of lionfish on 12 shallow coral reefs in the Bahamas in relation to time of day and prey availability.
