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.

MERCURY LEVELS AND FISH CONSUMPTION SURVEYED AT A GULF OF MEXICO FISHING RODEO Kimberly Warner Jacqueline Savitz ACKNOWLEDGEMENTS: We wish to thank the organizers of the 73rd Annual Deep Sea Fishing Rodeo, particularly Pat Troup, Mike Thomas, and the anglers, the National Seafood Inspection Lab, the Dauphin Island Sea Lab, and the invaluable assistance of Dr. Bob Shipp, Dr. Sean Powers, Melissa Powers, the hard working DISL graduate students and Oceana staff, including Gib Brogan, Phil Kline, Mike Hirshfield, Suzanne Garrett, Bianca Delille, Sam Haswell, Heather Ryan and Dawn Winalski.

Unfortunately, anglers have not had the in- formation they need to help them decide which fish may be safer to eat, despite the fact that recreational anglers and their families typically eat more fish than the average population. In fact, recent studies have found that people who live in coastal areas of the United States have higher levels of mercury in their blood than residents from inland areas.1 The purpose of this report is to help provide infor- mation to recreational anglers in the Gulf of Mexico on which fish may be higher in mercury than others, which would be safer to eat, and which species are in need of further monitoring.

All rights reserved Reproductive Cycle of the Pacific Bonito, Sarda chilensis (Scombridae), from Northern Chilel STEPHEN R.

Age and Growth of Atlantic Bonito (Sarda Sarda) in Western Mediterranean Sea
SCRS/2007/141 Collect. Vol. Sci. Pap. ICCAT, 62(5): 1649-1658 (2008) AGE AND GROWTH OF ATLANTIC BONITO (SARDA SARDA) IN WESTERN MEDITERRANEAN SEA X. Valeiras1, D. Macías2, M.J. Gómez2, L. Lema2, E. Alot2, J.M. Ortiz de Urbina2 and J.M. de la Serna2 SUMMARY A total of 136 dorsal fin spines from western Mediterranean Atlantic bonito were analyzed from 2003 to 2006 for ageing and growth studies. The length of the aged individuals ranged from 40 to 61 cm. Fish ages ranged 1 to 3 years old and the mean lengths by age were calculated for males and females. Growth parameter estimates were calculated from 136 cut spine sections which provided readable growth annuli by sex. The standard von Bertalanffy growth function was used to fit length at- age data.The growth parameters based on standard von Bertalanffy growth function are the following for both sexes: L∞ (asymptotic length)=62.5 cm, k (growth coefficient)=0.719, t0 (age at zero length)=-1.21. The relationships between FL and dorsal fin spine diameter were calculated for both sexes. Age-length keys were provided for catch at age calculation application. RÉSUMÉ Un total de 136 épines de la nageoire dorsale de bonitous de l’ouest de la Méditerranée ont été analysées de 2003 à 2006 aux fins d’études de détermination de l’âge et de croissance. La taille (longueur à la fourche) des individus dont l’âge avait été déterminé oscillait entre 40 et 61 cm. L’âge des poissons allait de 1 à 3 ans et les tailles moyennes par âge ont été calculées pour les mâles et pour les femelles.
