Preliminary observation of mantis shrimp breeding success in captivity
Mantis shrimps (Crustacea: Stomatopoda) are potential aquaculture species as they are constantly fished from the wild to satisfy demands of the seafood industry. Breeding capacity of mantis shrimps in captivity is scarce and implies a gap in this area to achieve successful aquaculture practices for this species. A preliminary observation was conducted with locally obtained mantis shrimps Miyake...
متن کاملDevelopment of breeding and fingerling production techniques for endangered long-whiskered catfish Sperata aor in captivity
An experiment was undertaken to develop a suitable seed production technique for Sperata aor in captivity. Naturally produced fry of aor was reared at different densities in nine nursery ponds 0.012 ha in size with an average depth of 0.8 m each. Three stocking densities tested, each of which was triplicated. Fry of aor stocked at 100,000/ha was designated as treatment-1 (T1), 150,000/ha as tre...

متن کاملThe causes of the low breeding success of European mink (Mustela lutreola) in captivity.
High among-individual variation in mating success often causes problems in conservation breeding programs. This is also the case for critically endangered European mink and may jeopardize the long-term maintenance of the species' genetic diversity under the European mink EEP Program. In this study, breeding success of wild and captive born European minks at Tallinn Zoological Garden are compare...
متن کاملGenerations in captivity increases behavioral variance: considerations for captive breeding and reintroduction programs
Long-term maintenance of captive populations followed by release of captive animals into the wild is one of many approaches to endangered species conservation. To assess captivity’s effects on behavior, a simulated predator was presented and response behaviors measured in oldfield mice, Peromyscus polionotus subgriseus. The animals tested were from four populations collected from Ocala National...
