Spawner size and the biological components of the reproduction process in Penaeus monodon Fabricius.
The biological components of the reproduction process of Penaeus monodon spawners collected from the wild along Tigbauan-Guimbal coastal area, Philippines, were evaluated. Data were collected on wet body weight, eggs per female, egg size, egg quality, hatching rate and percentage survival at the first zoea stage. There was a general trend for number of eggs per female and egg size to increase with increasing body weight. However, the larger spawners were not the most efficient in terms of number of eggs per unit body weight. There was a significant positive correlation between body weight and number of eggs per female. Larger eggs may be associated with larger body size. However, the size of individual eggs tends to be dependent upon the total number of eggs spawned per female.
Parado-Estepa, Fe D.; Honculada-Primavera, Jurgenne (Aquaculture Department, Southeast Asian Fisheries Development Center, 1988)Research on the maturation of Penaeus monodon at AQD has focused on three broad areas, namely, reproductive biology and ecology, induced maturation and broodstock management. Studies on reproductive biology provided ...
Primavera, Jurgenne; Lim, Chhorn; Borlongan, Emetrio (University of the Philippines at Los Baños, 1979)Pond-reared P. monodon were stocked in four 12-cu m flowthrough maturation tanks at 25 males and 50 females per tank; females were unilaterally ablated. The combinations of feeds for the morning and afternoon rations were ...
Gomes, Luiz A. O.; Honculada-Primavera, J. (Elsevier, 1993)The reproductive performance of unilaterally eyestalk-ablated wild male Penaeus monodon was compared with that of unablated prawns (controls). After being stocked for 6 weeks in flow-through tanks, ablated males showed ...
