Monsoon induced seasonality in the recruitment of Philippine fishes
Type: Book Chapter
The patterns of recruitment of 112 stocks of Philippine teleost fishes, from 23 families, 34 genera and 57 species, have been studied in detail. The annual recruitment patterns, which were obtained by the backward projection ...
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.
Application to shrimp stocks of objective meathods for the estimation of growth, mortality and recruitment-related parameters from length-frequency data (ELEFAN I and II)
Type: Book Chapter
This paper presents applications to several shrimp stocks of a new, computer-based set of methods for the detailed analysis of length-frequency data. These applications include the objective estimation of growth parameters, ...
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) ...
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 ...
An atlas of the growth, mortality and recruitment of Philippine fishes
Type: Report
This atlas presents the results of a detailed analysis of length-frequency data collected from 1957 to 1981 throughout the Philippines, covering 23 families, including 34 genera and 56 species representing 112 stocks ...
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.
