Effects of protective management on coral reef fishes in the Philippines
Type: Journal Article
The findings are presented of a study concerning the species composition and abundance of coral reef fish in the Philippines and their protection.
Assessment of Pterocaesio Pisang (Bleeker, 1853; family Caesionidae) at APO and Sumilon Islands in central Visayas, Philippines
Type: Journal Article
An analysis is made of length-frequency data of Pterocaesio pisang for the period March 1982-April 1983 in order to assess the stock at APO and Sumilon islands.
Estimation of natural mortality rates from selectivity and catch length-frequency data
Type: Journal Article
In conventional catch curves, the logarithms of the relative abundances of successive age groups are plotted against age, in order to obtain an estimate of the total instantaneous mortality rate, Z, from the slope of the ...
Growth, reproduction and mortality of the sea hare Dolabella auricularia (Gastropoda: Aplysiidae) in the Central Visayas, Philippines
Type: Journal Article
The growth parameters W infinity and K of the von Bertalanffy growth equation were estimated from size-frequency data of the sea hare D. auricularia using an objective, computer-based method. The results obtained from two ...
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-converted catch curves: a powerful tool for fisheries research in the Tropics (III: conclusion)
Type: Journal Article
A method is described for the determination of the selection curve of fishing gear from the shape of the ascending arm of a length-converted catch curve and growth parameters.
