Mass production in concrete tanks of sugpo Penaeus monodon Fabricius spawners by eyestalk ablation
MetadataShow full item record
Two batches of 196 and 181 P. monodon females were ablated on one eyestalk in March and July 1977, respectively, and a control batch of 180 unablated females was stocked in July 1977. The females were stocked with males in 120-ton concrete tanks with partial flowthrough of water and fed salted mussel (Modiolus metcalfei ) at 15% body weight daily. Total number of spawnings was 82 for the March-ablated group, 3 for the July-ablated group and 4 for the July unablated group. Maturation and mortality in relation to the moult cycle and tank plus water conditions are discussed.
