Does Climate Change Bolster the Case for Fishery Reform in Asia? Christopher Costello∗
Does Climate Change Bolster the Case for Fishery Reform in Asia? Christopher Costello∗ I examine the estimated economic, ecological, and food security effects of future fishery management reform in Asia. Without climate change, most Asian fisheries stand to gain substantially from reforms. Optimizing fishery management could increase catch by 24% and profit by 34% over business- as-usual management. These benefits arise from fishing some stocks more conservatively and others more aggressively. Although climate change is expected to reduce carrying capacity in 55% of Asian fisheries, I find that under climate change large benefits from fishery management reform are maintained, though these benefits are heterogeneous. The case for reform remains strong for both catch and profit, though these numbers are slightly lower than in the no-climate change case. These results suggest that, to maximize economic output and food security, Asian fisheries will benefit substantially from the transition to catch shares or other economically rational fishery management institutions, despite the looming effects of climate change. Keywords: Asia, climate change, fisheries, rights-based management JEL codes: Q22, Q28 I. Introduction Global fisheries have diverged sharply over recent decades. High governance, wealthy economies have largely adopted output controls or various forms of catch shares, which has helped fisheries in these economies overcome inefficiencies arising from overfishing (Worm et al. 2009) and capital stuffing (Homans and Wilen 1997), and allowed them to turn the corner toward sustainability (Costello, Gaines, and Lynham 2008) and profitability (Costello et al. 2016). But the world’s largest fishing region, Asia, has instead largely pursued open access and input controls, achieving less long-run fishery management success (World Bank 2017). -

From McDowell Group, Inc.: Jim Calvin (project oversight and editor), Dan Lesh (lead author/ analyst), Garrett Evridge (author/analyst) , Joe Jacobson (author/analyst), Paul Strickler (author/analyst). From Pacific States Marine Fisheries Commission: Bob Ryznar (project oversight and sub-contractor management), Jean Lee (data compilation and analysis) This report was produced and funded by the NOAA-NMFS’ Alaska Fisheries Science Center. Funding was awarded through a competitive contract to the Pacific States Marine Fisheries Commission and McDowell Group, Inc. The analysis was conducted during the winter of 2018 and spring of 2019, based primarily on 2017 harvest and market data. A final review by staff from NOAA-NMFS’ Alaska Fisheries Science Center was completed in June 2019 and the document was finalized in March 2016. Data throughout the report was compiled in November 2018. Revisions to source data after this time may not be reflect in this report. Typically, revisions to economic fisheries data are not substantial and data presented here accurately reflects the trends in the analyzed markets.

CALIFORNIA MARINE FISH LANDINGS FOR 1972 LEO PINKAS Marine Resources Region 1.1. INTRODUCTION The protection, propagation, and wise utilization of California's living marine resources (established as common property by statute, Section 1600, Fish and Game Code) is dependent upon the welding of biological, environment- al, economic, and sociological factors. Fundamental to each of these factors, as well as the entire management pro- cess, are harvest records. The California Department of Fish and Game began gathering commercial fisheries land- ing data in 1916. Commercial fish catches were first published in 1929 for the years 1926 and 1927. This report, the 32nd in the landing series, is for the calendar year 1972. It summarizes commercial fishing activities in marine as well as fresh waters and includes the catches of the sportfishing partyboat fleet. Preliminary landing data are published annually in the circular series which also enumerates certain fishery products produced from the catch. -

Recycled Fish Sculpture (.PDF)
Recycled Fish Sculpture Name:__________ Fish: are a paraphyletic group of organisms that consist of all gill-bearing aquatic vertebrate animals that lack limbs with digits. At 32,000 species, fish exhibit greater species diversity than any other group of vertebrates. Sculpture: is three-dimensional artwork created by shaping or combining hard materials—typically stone such as marble—or metal, glass, or wood. Softer ("plastic") materials can also be used, such as clay, textiles, plastics, polymers and softer metals. They may be assembled such as by welding or gluing or by firing, molded or cast. Researched Photo Source: Alaskan Rainbow STEP ONE: CHOOSE one fish from the attached Fish Names list. Trout STEP TWO: RESEARCH on-line and complete the attached K/U Fish Research Sheet. STEP THREE: DRAW 3 conceptual sketches with colour pencil crayons of possible visual images that represent your researched fish. STEP FOUR: Once your fish designs are approved by the teacher, DRAW a representational outline of your fish on the 18 x24 and then add VALUE and COLOUR . CONSIDER: Individual shapes and forms for the various parts you will cut out of recycled pop aluminum cans (such as individual scales, gills, fins etc.) STEP FIVE: CUT OUT using scissors the various individual sections of your chosen fish from recycled pop aluminum cans. OVERLAY them on top of your 18 x 24 Representational Outline 18 x 24 Drawing representational drawing to judge the shape and size of each piece. STEP SIX: Once you have cut out all your shapes and forms, GLUE the various pieces together with a glue gun. -

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.
