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 ...
Fish production, catches and the carrying capacity of the world oceans
Type: Journal Article
A brief review of the status of the world fisheries is presented with emphasis on the differences between catches (= landings + bycatch), biological production of fish, and predation (= production - catches). The ECOPATH ...
Catch and effort in the small-scale fisheries
Type: Book Chapter
The gears used by the small scale fishermen of San Miguel Bay, Philippines, are presented and classified. Numbers around the Bay and catch per effort of the various gears are estimated along with their annual fishing effort. ...
Biology, fisheries and culture of tropical groupers and snappers
Type: Conference Proceedings
Groupers and snappers are important fishery resources of the tropics and subtropics, where their high values have caused most of their stocks to be heavily exploited, some even to the point of collapse. Trends towards heavy ...
Developments in tropical reef fisheries science and management
Type: Book Chapter
Extinction is conceivable for some species, including aquarium-fish stocks of high value and limited geographical range, but a biological basis exists for management of such small fishes. Immediate data needs are much ...
Resolving multigear competition in nearshore fisheries
Type: Journal Article
This article briefly describes the intensive multidisciplinary 3 year research project conducted by the University of the Philippines and ICLARM to document the conditions of the fisheries and fishing communities of San ...
Primary production required to sustain global fisheries
Type: Journal Article
The mean of reported annual world fisheries catches for 1988-1991 (94.3 million t) was split into 39 species groups, to which fractional trophic levels, ranging from 1.0 (edible algae) to 4.2 (tunas), were assigned, based ...
Management of tropical coastal fisheries in Asia: an overview of key challenges and opportunities
Type: Conference Proceedings
Coastal fisheries are an important component of the fisheries sector and rural economy of tropical developing countries in Asia - generating food, employment and foreign exchange. In 1994, marine landings of these countries ...
Theory and management of tropical fisheries
Type: Conference Proceedings
The objectives of the workshop were designed to place emphasis on applications. It was perceived that the fisheries are at present so intense and the available information so limited, that a special effort should be made ...
Theory and management of tropical multispecies stocks: a review, with emphasis on the Southeast Asian demersal fisheries
Type: Working Paper
This paper consists of four main parts: a) the marine fisheries of Southeast Asia; b) the mathematical models; c)the Gulf of Thailand trawl fishery as a case study; and d) possible new approaches in the study and management ...
