Abstract
XX Iberian Symposium on Marine Biology Studies (SIEBM XX) , Braga, Portugal, 9 Sep - 12 Sep, 2019.
Highlights
At 17 oC, none of the megalopae moulted to the first juvenile crab
Most of the larval mortality occurred during the moulting process to the second zoea and megalopa stages and varied between larvae hatched from different females
Larval development was completed until zoea IV in the three temperatures and an additional stage (Zoea V) was observed at the lowest temperature treatment 17oC from some females
Summary
Tests were done through laboratory experiments under controlled conditions of salinity (35), photoperiod (12:12), and food (freshly mixed of Brachionus plicatilis and hatched Artemia nauplii), at three temperature treatments (17, 21 and 25°C). 24 active swimming larvae were reared in individual vials where water and food were changed every day, and moults and dead larvae were recorded daily. Six females per temperature treatment (18 females total) were maintained under the same salinity and photoperiod conditions.
