Daily Ration of Japanese Spanish Mackerel Scomberomorus Niphonius Larvae

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.

Estimating Age and Growth of Little Tunny, Euthynnus Alletteratus, Off the Coast of Senegal, Using Dorsal Fin Spine Sections
SUMMARY PAPER Estimating Age and Growth of Little Tunny, Euthynnus alletteratus, off the Coast of Senegal, Using Dorsal Fin Spine Sections PATRICE M. CAYRE 1 and TAIB DIOUP ABSTRACT Estimates of age were made from counts of growtb bands on dorsal spine sections of 491 little tunny, Euthynnus alletteratus, captured off the coast of Senegal during 1979. Analysis of marginal growtb bands (by montb) indicates that these bands are probably formed during tbe cold season (November-May). Mean size at estimated age was deter mined for tbe first 8 yr of life. These results, tbougb not validated, closely approximated other studies for young fisb (estimated ages 1-3), but were bigbly variable for older age categories. Tbe index of average percent error (E) for age nates from our study was 10.5% and infers good precision.

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.

Introduction Tunas and Other Large Highly-Migratory Species
CHAPTER 1: AUTHOR: LAST UPDATE: OVERVIEW SECRETARIAT Jan. 25, 2006 1. Overview 1.1 What is ICCAT? Introduction Tunas and other large highly-migratory species are typically assessed and managed through international arrangements. Since the distribution of such stocks is not limited to the waters of any single sovereign nation, such arrangements are necessary in order to share the available research and fishery information. The International Commission for the Conservation of Atlantic Tunas is responsible for the conservation of tunas and tuna-like species in the Atlantic Ocean and adjacent seas. The organization was established at a Conference of Plenipotentiaries, which prepared and adopted the International Convention for the Conservation of Atlantic Tunas signed in Rio de Janeiro, Brazil, in 1966. After a ratification process, the Convention entered formally into force in 1969. The official languages of ICCAT are English, French and Spanish. The Commission's work requires the collection and analysis of statistical information relative to current conditions and trends of the fishery resources in the Convention. About 30 species are covered by the Convention: Atlantic bluefin (Thunnus thynnus thynnus), yellowfin (Thunnus albacares), albacore (Thunnus alalunga), bigeye tuna (Thunnus obesus) and skipjack (Katsuwonus pelamis); swordfish (Xiphias gladius); billfishes such as white marlin (Tetrapturus albidus), blue marlin (Makaira nigricans), sailfish (Istiophorus albicans) and spearfish (Tetrapturus pfluegeri & T. belone); mackerels such as spotted Spanish mackerel (Scomberomorus maculatese) and king mackerel (Scomberomorus cavalla); and, small tunas like black skipjack (Euthynnus alletteratus), frigate tuna (Auxis thazard), and Atlantic bonito (Sarda sarda). Southern bluefin tuna (Thunnus maccoyii) is also part of the Convention, although currently the primary responsibility for assessing and managing this species rests with the Commission for the Conservation of Southern Bluefin Tuna (CCSBT).
