Type: Journal Article
There are concerns about the sustainability of the world’s capture fisheries at the current total level of ~96 million tons per year. The warning signals are an increase in the proportion of depleted or recovering stocks, ...
On the interrelationships between naturual mortality, growth parameters, and mean environmental temperature in 175 fish stocks
Type: Journal Article
A compilation of values for the exponential coefficient of natural mortality (M) is given for 175 different stocks of fish distributed in 84 species, both freshwater and marine, and ranging from polar to tropical waters.
A survey of ichthyofauna of Lake Kanyaboli and other small waterbodies in Kenya: alternative refugia for endangered fish species
Type: Journal Article
In 1988, the World Conservation Union (WCU) Red Book of Endangered Species listed hundreds of endemic fishes of Lake Victoria under a single heading - "ENDANGERED". Most of the endemic native food fishes are either endangered ...
Length-weight relationship of fishes from a seagrass meadow in Negros Oriental, Philippines
Type: Journal Article
The parameters a and b of the length-weight relationship of the form W=aL super(b) were estimated for 13 fish species sampled in a seagrass meadow in Negros Oriental, Philippines. Also, to facilitate conversions, the ...
A workshop on length-based methods in fisheries analysis in the Solomon Islands
Type: Journal Article
A brief account is given of a workshop organized by the South Pacific Research Coordination Unit of the ForumFisheries Agency in order to examine the use of length frequency data as a tool in fish population assessment in ...
