Maturity, spawning and feeding intensity of cobia Rachycentron canadum (Linnaeus, 1766) in northwest coast of India
An attempt was made to provide some vital aspects of reproductive biology of cobia Rachycentron canadum (Linnaeus, 1766). Samples for a period of two years from an exploratory vessel and from the landing centers of Mumbai were used for the study. The average sex ratio between males and females observed was 1:0.80. Dominance of the number of females above the size of 100 cm was noticed. The size...

متن کاملThyroid gland development in Rachycentron canadum during early life stages.
The aim of this study was to describe the ontogeny of thyroid follicles in cobia Rachycentron canadum. Larvae were sampled daily (n=15 - 20) from hatching until 15 dah (days after hatching). Following, larvae were sampled every two days by 28 dah; a new sample was taken at 53 dah. The samples were dehydrated, embedded in Paraplast, and sections of 3 µm were dewaxed, rehydrated and stained with ...
متن کاملEstimate of the Maximum Sustainable Yield of Sergestid Shrimp in the Waters off Southwestern Taiwan
The sergestid shrimp, Sergia lucens is one of the major marine resources in the waters off southwestern Taiwan. The maximum sustainable yield (MSY), total allowable catch (TAC) and fishing effort at MSY (EMSY) of the sergestid shrimp in this area were estimated to be 1008 tons, 907 tons and 11292 vessel-day, respectively by using the surplus production model with deterministic observation-error...
