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 ...
Growth, natural mortality, length-weight relationship, maximum length and length-at-first-maturity of the coelacanth Latimeria chalumnae
Type: Journal Article
This study revisit the information published on life-history parameters of Latimeria chalumnae, re-analyses growth and length-weight relationships, and provides new estimates for maximum length, length and age-at-first ...
Effect of freshwater toxic and non toxic cyanobacteria, (Microcystis aeruginosa) strains on some biochemical parameters of Oreochromis niloticus
Type: Journal Article
This study was planned to determine the grazing rate of O. niloticus from both toxic and non toxic strains of Microcystis aeruginosa with its effect on fish health through study of some clinical signs, hematological and ...
