Spawning in captivity and eggs and larvae quality of red porgy, Pagrus pagrus (L.).Abstract
Spontaneous spawning of red porgy was achieved in captivity by using photoperiod and temperature control systems along the year. During a four-month reproduction period females released in average about 0.2 times their own body weight in oocytes with an energy content of 5.71 J mg-1 wet weight. A total of 28.8 x 106 eggs and approximately 200 g of viable eggs (wet weight) per female kg were obtained. The eggs and larvae quality in terms of hatching and larval survival rates experienced a significant variation during the spawning season ranging between 0%-92% and 0.3%-33.2% respectively. Comments in reference to the probable causes of these variations and the need of carrying on with this line of research are presented.Journal
