The effect of temperature on the utilisation of yolk-sac and growth in terms of length of the larvae of cobia Rachycentron canadum (Linnaeus, 1766) was investigated. Five temperature levels viz., 29, 30, 31, 32 and 33°C were experimented with the newly hatched larvae for a total duration of 52 hours post-hatch (hph). A clear-cut trend of increase in larval length with increase in temperature was noted. The maximum length recorded was 4.41±0.11 mm at 33°C by the end of the experiment. The yolk-sac volume decreased proportionately with rise in temperature. At the end of 52 hph, the lowest yolk-sac volume was recorded at temperature range of 31 to 33°C. Results of the present study suggest that temperature plays a vital role in the yolk-sac utilisation as well as on growth of cobia larvae. Not Available |
