| Popis: |
Winter field collected animals were maintained in a closed seawater system with a salinity of 30 ppt and gradually acclimated to 25±1°C over a 2.5 week period. A 12:12 day:night cycle was maintained. The crabs were fed a diet of frozen fish, scallops, and clams. Molting and copulation occurred 40 to 57 days after acclimation. Egg masses were produced 82 to 109 days after mating. One female produced a second sponge 45 days later. Larvae from the first two egg masses were reared in the laboratory to the first crab stage. Survival was within the normal range for laboratory culture of this species. This study indicates that it is feasible to maintain a continually reproducing population of Menippe mercenaria under laboratory conditions, which in conjunction with larval mass culture systems could be used to provide seedling stocks for natural resource management and mariculture. |
