Effect of temperature on spawning of Penaeus merguiensis
MetadataShow full item record
The maturation rate and spawning performance of ablated Penaeus merguiensis were significantly (P<0.05) higher at 27àthan at 23î Increasing the temperature from 23àto 27àfurther improved spawning performance (P<0.05), whereas reducing the temperature from 27àto 23àimpaired spawning. The effect of temperature during the inducing period was more critical than during the holding period. Prawn growth (% of weight gain), however, was not different between 23àand 27àover the 60-day experimental period (P>0.05).
