Restoring small-scale fisheries for tropical sea cucumbers
Type: Journal Article
Overfishing threatens to extinguish local fisheries for valuable tropical sea cucumbers by reducing population densities to the point where reproductive success trails behind natural mortality (known as depensation or the ...
FISHSIM: a generalized fishery simulation model
Type: Journal Article
This paper describes a general bioeconomic model, FISHSIM, which uses traditional equations and submodel to represent the biological parameters of a fish stock, and simple financial equations to represent profitability of ...
Restocking and stock enhancement of coastal fisheries: Potential, problems and progress
Type: Journal Article
The demand for fish is expected to rise substantially by 2020. Although aquaculture must provide much of the additional fish, it remains to be seen whether restored or enhanced capture fisheries can also help fill the ...
Fifty years of reservoir fisheries in Mettur Dam, India: some lessons
Type: Journal Article
The paper outlines briefly the history of the fishery in a dam reservoir in India. The reservoir was very productive in its early years, with support from a seed farm, ice plant, cold storage and regulated entry of fishery. ...
An approach to the assessment of the finfish fisheries of the Caribbean Community
Type: Journal Article
This paper briefly outlines the implications of making a decision on the most appropriate alternative for carrying out stock assessments and the reasons for previous failures to conserve finfish stocks for sustainable use. ...
An analysis of production factors in carp farming in Andhra Pradesh, India
Type: Journal Article
Three major carp species, viz. catla Catla, Labeo rohita and mrigal Cirrhinus mrigala, are farmed in polyculture systems in the southern state of Andhra Pradesh, India. A survey of 189 carp farms was undertaken, and principal ...
Beverton and Holt equations: spreadsheet functions and uncertainty
Type: Journal Article
This contribution illustrates how modern spreadsheets aid the calculation and visualization of yield models and how the effects of uncertainties may be incorporated using Monte Carlo simulation. It is argued that analogous ...
ICLARM's Resource Development and Management Program: the Tropical Stock Assessment Research Project
Type: Journal Article
The project was conceived to identify and overcome the major constraints preventing the development of stock assessment techniques appropriate to tropical stocks. These constraints are listed and the project's programme of ...

Type: Journal Article
This contribution provides an overview of the marine capture fisheries off the coast of Karnataka State, India. It covers the main fisheries and fishing gears, production trends (by main species /groups and gears), assessment ...
Spawning stock biomass-per-recruit analysis: a timely substitute for stock recruitment analysis
Type: Journal Article
Relative biomass per recruit of adult (i.e. sexually mature) fin to shellfish is shown to help in identifying levels of fishing mortality likely to lead to recruitment overfishing. This is illustrated with data from a ...
