VPA estimates of fishing mortality and exploited biomass from Sardinella aurita catch-at-length data in eastern Venezuela
Type: Journal Article
In this study, length-frequency data on Spanish sardine (Sardinella aurita) from northeastern Venezuela were analyzed for the period 1967-1989. Average growth parameters for the von Bertalanffy equation were established ...
Selective breeding trait preferences for farmed tilapia among low-income women and men consumers in Egypt; Implications for pro-poor and gender-responsive fish breeding programmes
Type: Journal Article
A number of studies have highlighted the promising growth of Egyptian tilapia aquaculture and the role of genetically improved strains in this development, such as the Abbassa Nile tilapia (Oreochromis niloticus, Linneaus, ...
The good, the bad, and the ugly: a critical look at species and their institutions from a user's perspective
Type: Journal Article
Over the past eight years my colleagues and I have been involved in a major project to make key information on fishes available to users, especially in developing countries. There are about 25 000 species of fishes in the ...
A mechanism for the juvenile-to-adult transition in fishes
Type: Journal Article
The mechanisms used by physiologists and fishery biologists to explain why fish become mature are shown to be wanting. The hypothesis is presented that diminishing oxygen supply per unit weight serves in growing fish as ...
Length-weight relationships of Penaeus monodon reared in semi-intensive culture systems of Kerala, India
Type: Journal Article
The results of a study on length-weight relationships of Penaeus monodon, reared in fertilized ponds in Kerala, India, and fed three different supplementary feeds are presented.
Global human footprint on the linkage between biodiversity and ecosystem functioning in reef fishes
Type: Journal Article
Difficulties in scaling up theoretical and experimental results have raised controversy over the consequences of biodiversity loss for the functioning of natural ecosystems. Using a global survey of reef fish assemblages, ...
Population dynamics of Metapenaeus ensis (Penaeidae) in the Gulf of Papua, Papua New Guinea
Type: Journal Article
Growth, total mortality and seasonality of recruitment of male Metapenaeus ensis (Penaeidae) were determined based on length-frequency data (n = 9007) collected in 1988 in the Gulf of Papua, Papua New Guinea.
Aquaculture and fisheries for nutrition: Towards a nutrition-sensitive approach
Type: Journal Article
This article explains the concept of a "nutrition-sensitive approach" to aquaculture and fisheries and provides insights into the ways in which this approach, if widely applied, could create large impacts on the nutritional ...
Growth and survival of olive barb, Puntius sarana (Hamilton 1822) larvae produced with cryopreserved versus fresh sperm
Type: Journal Article
Despite the success in fertilization and hatching of fish eggs with cryopreserved sperm, report on growth and survival of larvae produced from frozen-thawed sperm is inadequate. This study evaluates the applicability of ...
A note on the inverse function of the von Bertalanffy growth function
Type: Journal Article
Parameter estimates of the von Bertalanffy growth function (VBGF) and its inverse function, based on length-at-age and age-at-length data for Tilapia rendalli (Cichlidae) and Salmo trutta (Salmonidae) were derived using a ...
