Stomachs were collected opportunistically from wahoo (n = 321) that were weighed (TW, kg) and measured (FL, mm) at fishing tournaments during 1997 - 2007. Stomachs were frozen and later thawed for removal and preservation (95% ethanol) of contents to facilitate their examination and identification. Empty stomachs (n = 71) comprised 22% of the total collec- tion. Unfortunately, the preserved, un-examined contents from 123 stomachs collected prior to Hurricane Katrina (August 2005) were destroyed during the hurricane. Consequently, assessments of wahoo stomach contents reported here were based on the con- tents of the 65 ‘pre-Katrina’ stomachs, in addition to the contents of 62 stomachs collected ‘post-Katrina’ during 2006 and 2007, for a total of 127 stomachs. Wahoo with prey in their stomachs ranged 859 - 1,773 mm FL and 4.4 - 50.4 kg TW and were sexed as: 31 males, 91 females and 5 sex unknown. -

The work concentrated on the fishing gears, length of fishes, total landings and market price of the catch and highlighted the prospects of the fishery in Bangladesh. Four commercially important species of mackerels and tuna viz. Scomberomorus guttatus, Scomberomorus commerson, Rastrelliger kanagurta, and Euthynnus affinis were included in the study. About 95% of mackerels and tuna were caught by drift gill nets and the rest were caught by long lines ( 4%) and marine set-bag-net (1 %). Average monthly total landing of mackerels and tunas was about 264 t, of which 147 t landed in Cox's Bazar and 117 tin Chittagong sites. Total catches of the four species in Cox's Bazar and Chittagong sites were found to be 956 and 762 t, respectively. The poor landing was observed during January-February and the peak landing was in November and July. Gross market value of the annual landing of mackerels and tunas (1,718 t) was found to be 1,392 lakh taka. -

Daily Ration of Japanese Spanish Mackerel Scomberomorus Niphonius Larvae
FISHERIES SCIENCE 2001; 67: 238–245 Original Article Daily ration of Japanese Spanish mackerel Scomberomorus niphonius larvae J SHOJI,1,* T MAEHARA,2,a M AOYAMA,1 H FUJIMOTO,3 A IWAMOTO3 AND M TANAKA1 1Laboratory of Marine Stock-enhancement Biology, Division of Applied Biosciences, Graduate School of Agriculture, Kyoto University, Sakyo, Kyoto 606-8502, 2Toyo Branch, Ehime Prefecture Chuyo Fisheries Experimental Station, Toyo, Ehime 799-1303, and 3Yashima Station, Japan Sea-farming Association, Takamatsu, Kagawa 761-0111, Japan SUMMARY: Diel successive samplings of Japanese Spanish mackerel Scomberomorus niphonius larvae were conducted throughout 24 h both in the sea and in captivity in order to estimate their daily ration. Using the Elliott and Persson model, the instantaneous gastric evacuation rate was estimated from the depletion of stomach contents (% dry bodyweight) with time during the night for wild fish (3.0–11.5 mm standard length) and from starvation experiments for reared fish (8, 10, and 15 days after hatching (DAH)). Japanese Spanish mackerel is a daylight feeder and exhibited piscivorous habits from first feeding both in the sea and in captivity. Feeding activity peaked at dusk. The esti- mated daily ration for wild larvae were 111.1 and 127.2% in 1996 and 1997, respectively; and those for reared larvae ranged from 90.6 to 111.7% of dry bodyweight. Based on the estimated value of daily rations for reared fish, the total number of newly hatched red sea bream Pagrus major larvae preyed by a Japanese Spanish mackerel from first feeding (5 DAH) to beginning of juvenile stage (20 DAH) in captivity was calculated to be 1139–1404. -
Simulations of Fishing Effects on the Southern Benguela Fish Community Using an Individual-Based Model: Learning from a Comparison with Ecosim
Ecosystem Approaches to Fisheries in the Southern Benguela Afr. J. mar. Sci. 26: 95–114 2004 95 SIMULATIONS OF FISHING EFFECTS ON THE SOUTHERN BENGUELA FISH COMMUNITY USING AN INDIVIDUAL-BASED MODEL: LEARNING FROM A COMPARISON WITH ECOSIM Y-J. SHIN*, L. J. SHANNON† and P. M. CURY* By applying an individual-based model (OSMOSE) to the southern Benguela ecosystem, a multispecies analysis is proposed, complementary to that provided by the application of ECOPATH/ECOSIM models. To reconstruct marine foodwebs, OSMOSE is based on the hypothesis that predation is a size-structured process. In all, 12 fish species, chosen for their importance in terms of biomass and catches, are explicitly modelled. Growth, repro- duction and mortality parameters are required to model their dynamics and trophic interactions. Maps of mean spatial distribution of the species are compiled from published literature. Taking into account the spatial component is necessary because spatial co-occurrence determines potential interactions between predatory fish and prey fish of suitable size. To explore ecosystem effects of fishing, different fishing scenarios, previously examined using ECOSIM, are simulated using the OSMOSE model. They explore the effects of targeting fish species in the southern Benguela considered to be predators (Cape hake Merluccius capensis and M. paradoxus) or prey (anchovy Engraulis encrasicolus, sardine Sardinops sagax, round herring Etrumeus whiteheadi). Simulation results are compared and are generally consistent with those obtained using an ECOSIM model. This cross-validation appears to be a promising means of evaluating the robustness of model outputs, when separate validation of marine ecosystem models are still difficult to perform. -

This represents a new host record for N. phaioplueura and its fourth record from the Seto Inland Sea and adjacent region. Key words: Cymothoidae, fish parasite, Isopoda, Nerocila phaiopleura, new host record, Scomber japonicus INTRODUCTION The Hōyo Strait is located between the western Seto Inland Sea and the Bungo Channell in western Japan. This strait is famous as a fishing ground of two perciform fishes of high quality, viz., chub mackerel, Scomber japonicus Houttuyn, 1782 (Scombridae), and Japanese jack mackerel, Trachurus japonicus (Temminck and Schlegel, 1844) (Carangidae), both of which are currently called“ Seki-saba” and“ Seki-aji”, respectively, as registered brands (e.g., Ishida and Fukushige, 2010). The brand names are well known nationwide, and the price of the fishes is very high (up to 5,000 yen per kg). Under these situations, the fishermen working in the strait pay much attention to the parasites of the fishes they catch because those fishes are almost exclusively eaten raw as“ sashimi.” Recently, a chub mackerel infected by a large parasite on the body surface (Fig. -

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). -
