Transportation methods for restocking of juvenile sea cucumber, Holothuria scabra.
Type: Journal Article
The sandfish, Holothuria scabra, is a heavily exploited sea cucumber species. Minimising stress in the transportation of hatchery-produced sandfish juveniles to release sites is critical for successful restocking. Replicate ...
Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
Type: Journal Article
Reports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of different ...
Effect of salinity on carrying capacity of adult Nile tilapia Oreochromis niloticus L. in recirculating systems
Type: Journal Article
Effect of salinity on carrying capacity of a recirculation system for Nile tilapia, Oreochromis niloticus L.; production was assessed. Survival, growth and feed conversion ratio of adult Nile tilapia fed 30% crude protein ...
Restocking the sea cucumber Holothuria scabra: sizing no-take zones through individual-based movement modelling
Type: Journal Article
The valuable sea cucumber Holothuria scabra, known as ‘sandfish’, has potential for restocking. However, there is little information available to determine the size of the no-take zones (NTZs) needed to protect the released ...
Restocking and stock enhancement of coastal fisheries: Potential, problems and progress
Type: Journal Article
The demand for fish is expected to rise substantially by 2020. Although aquaculture must provide much of the additional fish, it remains to be seen whether restored or enhanced capture fisheries can also help fill the ...
Some aspect of population dynamics of three penaeid shrimp (P.monodon, P.semisulcatus and M.monoceros) from the Bay of Bengal, Bangladesh.
Type: Journal Article
In the Bay of Bengal of Bangladesh area the values of asymptotic length (La) for tiger shrimp (Penaeus monodon), green tiger shrimp (Penaeus semisulcatus) and brown shrimp (Metapenaeus monoceros) were found to be 30.0 cm, ...
Efficacy of chemical markers and physical tags for large-scale release of an exploited holothurian.
Type: Journal Article
Hatchery-produced juveniles need to be distinguished from wild conspecifics in order to evaluate the success of restocking experiments and stock enhancement. The commercially valuable sea cucumber Holothuria scabra, or ...
Advanced nursing of Clarias gariepinus (Burchell, 1822) fingerlings in earthen ponds, through recycling of tilapia recruits
Type: Journal Article
In an attempt to improve the stocking size and yield of Clarias gariepinus, small fingerlings (average weight=3 g) of the type usually produced by African hatcheries were stocked together with tilapia (Oreochromis niloticus) ...
Enhancing the productivity of small waterbodies
Type: Journal Article
Most small waterbodies were built for irrigation and/or drinking water storage for humans and livestock, but have also been shown to play an important role in watershed management. Apart from natural lakes, small waterbodies ...
Relative Importance of Various Predators in Clarias gariepinus Fry Mortality in Cameroon
Type: Journal Article
To estimate the relative importance of the most common predators of Clarias gariepinus fry, increasing levels of protection were afforded to exclude amphibians, aquatic arthropods and birds. At a stocking density of 10 ...
