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. -

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. -

A5 By-catch Species APPENDIX 5: BY-CATCH SPECIES A.5 By-catch species By-catch is the unintentional/incidental capture of non-target species during fishing operations. Different types of fisheries have different types and levels of by-catch, depending on the gear used, the time, area and depth fished, etc. Article IV of the Convention states: "the Commission shall be responsible for the study of the population of tuna and tuna-like fishes (the Scombriformes with the exception of Trichiuridae and Gempylidae and the genus Scomber) and such other species of fishes exploited in tuna fishing in the Convention area as are not under investigation by another international fishery organization". The following is a list of by-catch species recorded as being ever caught by any major tuna fishery in the Atlantic/Mediterranean. Note that the lists are qualitative and are not indicative of quantity or mortality. Thus, the presence of a species in the lists does not imply that it is caught in significant quantities, or that individuals that are caught necessarily die.

The Story of Atlantic Bluefin Tuna Is One of Intrigue, Filled with International Drama, Mafia Connections, and Plot Twists Worthy of a Movie
A brief from Sept 2017 Richard Herrmann The Story of Atlantic Bluefin Science-based management will ensure a healthy future Overview The story of Atlantic bluefin tuna is one of intrigue, filled with international drama, mafia connections, and plot twists worthy of a movie. The main character—Thunnus thynnus—is the largest and most athletic tuna, which can grow to the size of a small car and travel nearly as fast as one too. An Atlantic bluefin starts out no bigger than an eyelash and grows to several hundred pounds and more than 6 feet in length in less than a decade. Unlike most fish species, Atlantic bluefin are warm-blooded; the heat created in their huge swimming muscles enables bursting speed, sharp vision, and thought processing second to none in the fish world. They are among the Atlantic’s top predators, with few species they won’t eat—and even fewer that eat them. The fleets of fishing vessels plying the Atlantic—and hoping to cash in on the value that the species has in sushi markets in Japan and high-end restaurants around the world—present the greatest threat to the Atlantic bluefin. Fishermen are often paid more than $10,000 for a single Atlantic bluefin right at the dock. The value of a high- quality fish at the final point of sale can be tens of thousands of dollars. These transactions add up to be big business. A recent estimate set the value of Atlantic bluefin fishing at nearly $200 million at the dock in 2014— and over $800 million at the final point of sale.1 Experts estimate that, pound for pound, this species is the most valuable tuna in the world and likely the most valuable fish in the Atlantic Ocean or the Mediterranean Sea. -
