The relationships between gill surface area and growth performance in fish: a generalization of von Bertalanffy's theory of growth
Type: Journal Article
This paper is an attempt to interpret some of the data on fish growth available in the literature, emphasis is being given to a reassessment of von Bertalanffy's theory of growth as applied to fishes.
Integrated rice-fish culture: increased productivity from deepwater ricelands in West Bengal
Type: Journal Article
A discussion is presented on the potential for integrated rice-fish culture systems in West Bengal as a means of not only increasing animal protein production but also of generating income for rural residents. Surveys ...
Preliminary bibliography of rice-fish culture
Type: Book
Over 300 references to research and development of the combined farming of rice and fish are listed.
The fishes and their ecology
Type: Report
An annotated list of 188 species of fishes recorded from San Miguel Bay, Philippines is presented. Of these, 48% are euryhaline marine species. The most abundant fishes belong to marine species whose representatives are ...
On the seasonal growth, monthly recruitment and monthly biomass of Peruvian anchoveta (Engraulis ringens) from 1961 to 1979
Type: Book Chapter
The paper reports on the application to the anchoveta of a newly developed set of methods for the investigaton of exploited fish stocks. the set of methods are incorporated in the ELEFAN (Electronic Length Frequency Analysis) ...
Rice-fish practices in Ifugao Province, Philippines
Type: Journal Article
Ifugao lies in the Cordillera Mountains in the north-central part of Luzon. It is famous for its colorful inhabitants, lush forests, crystal waters and magnificent rice terraces. The people have traditionally practiced ...
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 ...
Studying single-species dynamics in a tropical multispecies context
Type: Book Chapter
Some methods available for the study of the population dynamics of tropical fish are reviewed; emphasis is given to questions of growth, mortality and recruitment, and to relatively new approaches, such as aging by means ...
Length-converted catch curves: a powerful tool for fisheries research in the Tropics (part 1)
Type: Journal Article
A number of methods are available with the help of which total mortality (Z) can be estimated from length-frequency data. Thus it is possible to obtain reasonable estimates of Z from the mean length in a representative ...
