Bermuda's Marine Reserve
POTENTIAL IMPACTS OF BERMUDA’s MARINE RESERVE ON SPORTFISHING TOURISM The Need to Explore Other Options ECONOMIC RETURNS CAN FLOW TO COASTAL NATIONS that Implement Billfish Conservation Measures Sportfishing eco-tourism is a strong economic driver for communities. Visting anglers are driven by the likelihood of catching a lot of billfish. Anticipated quality of a billfishing trip greatly influences anglers’ destination choices. Anglers most often select fishing destination where commercial fishing is restrained. Responsible management of billfish can maximize catch rates and economic returns to communities.

Little Fish, Big Impact: Managing a Crucial Link in Ocean Food Webs
little fish BIG IMPACT Managing a crucial link in ocean food webs A report from the Lenfest Forage Fish Task Force The Lenfest Ocean Program invests in scientific research on the environmental, economic, and social impacts of fishing, fisheries management, and aquaculture. Supported research projects result in peer-reviewed publications in leading scientific journals. The Program works with the scientists to ensure that research results are delivered effectively to decision makers and the public, who can take action based on the findings. The program was established in 2004 by the Lenfest Foundation and is managed by the Pew Charitable Trusts (www.lenfestocean.org, Twitter handle: @LenfestOcean). The Institute for Ocean Conservation Science (IOCS) is part of the Stony Brook University School of Marine and Atmospheric Sciences. It is dedicated to advancing ocean conservation through science. IOCS conducts world-class scientific research that increases knowledge about critical threats to oceans and their inhabitants, provides the foundation for smarter ocean policy, and establishes new frameworks for improved ocean conservation.

Acoustic Characteristics of Forage Fish Species in the Gulf of Alaska and Bering Sea Based on Kirchhoff-Approximation Models
1839 Acoustic characteristics of forage fish species in the Gulf of Alaska and Bering Sea based on Kirchhoff-approximation models Stéphane Gauthier and John K. Horne Abstract: Acoustic surveys are routinely used to assess fish abundance. To ensure accurate population estimates, the characteristics of echoes from constituent species must be quantified. Kirchhoff-ray mode (KRM) backscatter models were used to quantify acoustic characteristics of Bering Sea and Gulf of Alaska pelagic fish species: capelin (Mallotus villosus), Pacific herring (Clupea pallasii), walleye pollock (Theragra chalcogramma), Atka mackerel (Pleurogrammus monopterygius), and eulachon (Thaleichthys pacificus). Atka mackerel and eulachon do not have swimbladders. Acous- tic backscatter was estimated as a function of insonifying frequency, fish length, and body orientation relative to the incident wave front. Backscatter intensity and variance estimates were compared to examine the potential to discrimi- nate among species. Based on relative intensity differences, species could be separated in two major groups: fish with gas-filled swimbladders and fish without swimbladders. The effects of length and tilt angle on echo intensity depended on frequency. Variability in target strength (TS) resulting from morphometric differences was high for species without swimbladders. Based on our model predictions, a series of TS to length equations were developed for each species at the common frequencies used by fisheries acousticians.
