In addition to tagging data, biological data have been collected for fish which were damaged and remained on deck (some of the biological measurements require the fish dead). 3975 fish were sampled this way(YFT, BET,SKJ...).Biological data include lengths (FL, FDL, CL), weight, sex, sex maturity, gonad weight, liver weight, stomach content weight (not for all fish on deck). The fish used for this activity are not tagged and related data are thus not part of the final tagging data. Since the fish are not recovered by professional fishing vessels, the spatial location is accurate (from GPS). Biological data (eg length, weight of individuals or related organs, tissue samples) have been collected on individuals of main tropical tuna species (YFT, SKJ ALB, BET). Samples have been collected on tissues (gut, liver, stomach..) or otolith.Biological data collected on recovered tagged tuna are managed in antother dataset.fra@C'est un jeu de données de 3975 lignes (sur yft, bigeye, skj...). poids du foie, des gonades, périmètre thoracique. Les données biologiques supplémentaires (...) sont accessibles mais gérées séparément des données de tagging. Certains individus ont fait l'objet de collecte de données biologiques (biologicaldatasampling), parmi ces individus, il y a un mélange d'individus marqués (indications dans les commentaires avec le numéro de marque) et de no marqués (majoritaires)Le contexte d’observation est décrit précisément dans les tables ”CRUISE”, ”ACTIVITY” qui rapportent les activités lors des différentes campagnes de marquage.les observations réalisées sur les individus bléssés: localisation, espèce, taille (Fork Length fl, First Dorsal Length fdl, Round Length rl, tp, Weight of the whole fish in 1/10 kg, Ungutted weight in 1/10 kg, Weight of the gut in 1/10 kg, Weight of the liver in grams, Weight of the two gonads together in grams, the sex of the fish either male or female (See LOOKUPSEX table), maturity stage, Volume of the stomach content in grams, Has the White muscle isotopes been sampled, has the White muscle been sampled, Has the liver been sampled, has the stomach been sampled,as the otolith been sampled, has the otolith Cap been sampled, if Dolphin Fish, has fin been sampled..)
