History and status of the San Miguel Bay fisheries
Type: Book Chapter
This paper reviews the available data on San Miguel Bay fisheries and their history, and contrasts "small-scale" and "trawl" fisheries, each of which land about half of the Bay's total catch of 15000 t / year. On the basis ...
Application of information on age and growth of fish to fishery management
Type: Book Chapter
Information on the age and growth of fish is usually related to one or several of the following items: construction of age/length keys for direct use in some assessment models (e.g. Virtual Population Analysis); estimation ...
A review of the ELEFAN system for analysis of length-frequency data in fish and aquatic invertebrates
Type: Book Chapter
Some aspects of the history and present role of length-based methods for the study of the growth, mortality and recruitment of fish invertebrate stocks are reviewd. The recently-developed ELEFAN (Electronic Length Frequency ...
Population dynamics of shortlived species with emphasis on squids
Type: Book Chapter
The features of short-lived fishes and invertebrates relevant to their population dynamics and exploitation are reviewed, with emphasis on methodological approaches, which could lead to improved management of squid stocks. ...
Recent developments in the methodology available for the assessment of exploited fish stocks of reservoirs
Type: Book Chapter
Recently developed fish stock assessment methods are briefly presented which could be used for the management of the fish stocks of African reservoirs. These methods include length-structured versions of Virtual Population ...
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 ...
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, ...

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 ...
