Length-weight relationships of commercially important marine fishes and shellfishes of the southern coast of Karnataka, India
Type: Journal Article
The parameters of the length-weight relationship of the form W = aLb are presented for 51 species of commercially important marine fishes and shellfishes caught along the southern coast of Karnataka, India. Samples from ...
Impact of stocking on yield in small reservoirs in Andhra Pradesh, India
Type: Journal Article
The relationships between surface area, stocking density and fish yield in 40 small reservoirs in India between 1994 and 1999 were examined. A significant positive correlation (r = 0.6) was found between stocking density ...
Releases of cultured sub-adult Trochus niloticus generate broodstock for fishery replenishment in Vanuatu
Type: Journal Article
The over-fished topshell Trochus niloticus ('trochus ') was cultured in Vanuatu and grown to sub-adult size (~40 mm) in sea cages. We released 200 of these trochus at each of five reef sites managed through Customary Marine ...
When should restocking and stock enhancement be used to manage sea cucumber fisheries?
Type: Report
Access to technology for producing and releasing juveniles is not a sufficient rationale to proceed with restocking (restoring stocks to the point where they can sustain regular harvests) or stock enhancement (increasing ...
Economics and management strategies for restocking sandfish in Vietnam
Type: Journal Article
This paper assesses the costs and benefits of a proposed project for restocking sandfish (Holothuria scabra) in Khanh Hoa Province, Vietnam. It identifies the key stakeholders, institutional framework, management and ...
Management of restocking and stock enhancement programs: the need for different approaches
Type: Book
Availability of technology for producing and releasing juveniles in the wild is not all that is required to proceed with programs for restocking (restoring stocks to the point where they can sustain regular harvests) and ...
The potential role of restocking and stock enhancement in the management of marine invertebrate fisheries in the Philippines
Type: Book Chapter
Throughout Southeast Asia, capture fisheries are no longer yielding their potential harvests - in many cases, the abundance of valuable species has been reduced to 10% of previous levels (Silvestre ef al., in press). The ...
Preservation of genetic diversity in restocking of the sea cucumber Holothuria scabra investigated by allozyme electrophoresis
Type: Journal Article
Population genetics analyses should be considered when releasing hatchery-produced juveniles of the sea cucumber Holothuria scabra when spawners from nonlocal populations are used. In New Caledonia, within-region genetic ...
Breeding and rearing of the sea cucumber Holothuria scabra in Viet Nam
Type: Report
The aims of this project were to develop large scale breeding and rearing methods for sandfish (Holothuria scabra) for commercial culture and/or restocking. Wild collected sea cucumbers were initially difficult to spawn, ...
Sandfish (Holothuris scabra) with shrimp (Penaeus monodon) co-culture tank trials
Type: Journal Article
Seven tank trials were undertaken involving the co-culture of sandfish and shrimp on sand. Sizes, stocking densities, feeding and other conditions were all varied. Results indicated that powdered sargassum did not support ...
