Response to bi-directional selection for frequency of early maturing females in Nile tilapia (Oreochromis niloticus)
(1999)Type: Journal ArticleThe present study was carried out to investigate a simple method for recording the occurrence of early maturing females in Nile tilapia at a fixed time after stocking and to estimate the response to bi-directional selection ... -
Length-weight relationships of freshwater fishes in Greece
(1999)Type: Journal ArticleLength-weight relationships were calculated for nine fish species from Lake Volvi (Macedonia, Hellas), caught with gillnets of five different mesh sizes between October 1995 and October 1996. In addition, length-weight ... -
Genetic variation in lytic activities of blood serum from Nile tilapia and genetic associations with survival and body weight
(1999)Type: Journal ArticleThe objective of the present investigation was to determine the genetic variation in lysozyme activity and SH activity in blood serum from a family material of Nile tilapia (O. niloticus) and to study the genetic associations ... -
Reducing the costs of restocking giant clams in Solomon Islands
(1999)Type: Journal ArticleOn many corals reefs in the Indo-Pacific, the larger species of giant clams (Tridacnidae) have either been eliminated or fished down to the point where the external fertilization of gametes is improbable. In the mid 1980s, ... -
Chemoreception studies in relation to feeding responses in the marine shrimps H. Milne Edwards (Penaeus indicus) and Miers (Metapenaeus dobsonii)
(1999)Type: Journal ArticleA study of chemoreception in relation to feeding and other factors involved showed that feeding behavior in shrimps can be triggered by chemical stimuli. However, Penaeus indicus and Metapenaeus dobsoni differ significantly ... -
Is epizootic ulcerative syndrome (EUS) specific fungus of fishes a primary pathogen?: an opinion
(1999)Type: Journal ArticleEarlier findings on epizootic ulcerative syndrome (EUS) and the present observation of the authors on transmission of EUS to snakehead (Channa sp.) without skin damage provide evidence to suggest that the invasive fungus ... -
Preliminary observation on culture of Penaeus monodon in low-saline waters
(1999)Type: Journal ArticleThe feasibility of semi-intensive culture of Penaeus monodon in low saline environment was investigated by comparing the growth and production in low (0.16-6.52 ppt) and high (4.60-19.42 ppt) saline areas at two stocking ... -
Towards policies for conservation and sustainable use of aquatic genetic resources
(1999)Type: Conference ProceedingsGenetic stock identification is increasingly needed for fisheries management. Genetic technologies are being developed to increase food production from aquaculture and to document and evaluate aquatic species, subspecies ... -
Potential of grouper hybrid (Epinephelus fuscoguttatus x E. polyphekadion) for aquaculture
(1999)Type: Journal ArticleThe marine grouper species are considered high value food fish in several countries. However, controlled breeding and hatchery production of grouper fingerlings for commercial farming is still in its infancy. Investigations ... -
The introduction of exotic fish in Sri Lanka with special reference to tilapia
(1999)Type: Journal ArticleIntroductions of exotic finfish between 1948 and 1953 are reported in this paper, with a brief reference to earlier and later introductions. Exotic fish were introduced principally to develop the potential for aquaculture ... -
Culture of tropical sea cucumbers for stock restoration and enhancement
(1999)Type: Journal ArticleSevere overfishing of sea cucumbers has occurred in most countries of the tropical Indo-Pacific. The release of juveniles is being examined at the ICLARM Coastal Aquaculture Centre in the Solomon islands as a means of ... -
Escalation in shrimp production in the Sierra Leone industrial fishery
