Fishes of the Mekong River-conservation and need for aquaculture
Type: Journal Article
Conservation and the potential and need for aquaculture of three major fish (Catlocarpio siamensis, Probarbus spp. and Pangasius gigas) of the Mekong River are discussed. Different steps being undertaken by the Cambodian ...
Interrelationships between swimming speed, caudal fin aspect ratio and body length of fishes
Type: Journal Article
The aspect ratio of the caudal fin of 63 fish species was measured. Swimming speeds for these species, representing 129 cases, were obtained from the literature for various fish sizes and speeds, i.e. "minimum speed" for ...
Age determination in tropical fish
Type: Journal Article
This essay presents evidence that check marks on the hard parts of tropical fishes can be used for aging these, in spite of the small seasonal temperature and other environmental oscillations prevailing in the tropics. The ...
A biochemical laboratory manual for species characterization of some tilapiine fishes
Type: Brief
This publication is both a manual for the biochemical analysis of several tissues of tilapias and an empirical demonstration of the methods for several species. Given the great and growing importance of tilapia in aquaculture ...
Length-weight relationships of freshwater fishes in Greece
Type: Journal Article
Length-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 ...
On improving the resolution of the recruitment patterns of fishes
Type: Journal Article
It is proposed that the "recruitment pattern" routine of the ELEFAN II program can be modified to allow, in addition to length-frequency data, the use of "restructured" data files. An example, based on Oreochromis niloticus ...
Length-weight relationships of Nigerian coastal water fishes
Type: Journal Article
Length-weight relationships (LWR) of 76 fish populations, distributed among 11 families, 18 genera and 22 species, inhabiting coastal (marine/brackish water ) ecosystems in Nigeria were estimated (39 cases) or assembled ...
Population dynamics of Nemipterus japonicus from the northern Arabian Sea, Pakistan
Type: Journal Article
Catch-per-effort and length-frequency data on threadfin bream Nemipterus japonicus (Nemipteridae) supplied by the staff of the R/V Dr. Fridtjof Nansen, covering the period September 1983 to June 1984, were analyzed using ...
The biometrics of marine fishes from the Gulf of Aden
Type: Journal Article
The growth parameters (L sub( infinity ), K, t sub(0)), total mortality and length-weight relationships of 23 speciesof fishes studied during a UNESCO-sponsored study of the fish populations of the Gulf of Aden, in the mid-1980s, ...
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 ...
