| Trawling for penaeid shrimps in Sofala Bank (central Mozambique) has been suggested to have major effects on the size of sea turtle populations. A total of 39 commercial fishers, fishery observers and enforcers were interviewed to assess the level of sea turtle catches in fishing operations and reported that at least 1,735±1,235 sea turtles are caught each fishing season of about seven months. Green turtle (Chelonia mydas, 48.4%), the loggerhead turtle (Caretta caretta, 25.8%) were the most common species, but catches also comprised the olive ridley (Lepidochelys olivacea),the hawksbill turtle (Eretmochelys imbricata) and the leatherback (Dermochelys coriacea). Over 54.8% of the incidents occur within a few miles of the small islands forming the Primeiras... |

| An experiment was designed totally randomized to study the influence of different rate of Na+/K+ (5, 30, 55, 70, 95 and 120). Massive mortality was presented to the sixth day of the treatments I and III (Na+/K+=5 and Na+/K+=120), to the seventh day the treatment V (Na+/K+=95) and to the eighth day of the treatment IV (Na+/K+=70). The treatments II and III (Na+/K+=30 and Na+/K+=55 respectively) they stayed in the time, when indicating a bigger tolerance of the postlarvae in these ranges of Na+/K+; however, the mortality of the treatment II were significantly bigger (p <0.01) that in the treatment III, in which 90-100% survival was observed. The results indicate a better physiologic answer of L. vannamei postlarvae to relationships Na+/K+... |
