Effects of adaptation to laboratory conditions on growth, molting, and food consumption of juvenile Farfantepenaeus duorarum (Decapoda: Penaeidae)

摘要: Growth patterns and biochemical analy!'>is al laboratory condilions (temperatUre 28°c' saJinily 22) were analyzed in juveniles wiJd pink shrimp, Farjr/!/tepenaeus duorarum (Burkenroad, 1939), eaught tlle Gulf of Mexica compared with cultivated (F2) organisms. Shrimp maintained for 55 days to monitor lhe molt frequency weight gain over lime. We detennined the molting wel ~'ejght per day experiment Wild shrimp had an average 10 ± 2.03 increase wet af 0.024 0.00 I g day- J; whereas cullivated shrinlp 11 2.15 a growth rate 0.084 0.002 day-l.
