Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
Type: Journal Article
Reports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of different ...

Type: Journal Article
Microcohorts of white shrimp, Litopenaeus vannamei, were sampled with a cast net at fortnightly intervals in the Mar Muerto Lagoon, Southern Mexico. Shrimp recruited to the lagoon throughout the sampling period (January ...
Field studies on prevention and biological control of the cyanobacterial blooms using Chlorella and Scenedesmus in the Nile tilapia farms
Type: Journal Article
This study aimed to investigate the use of green algae Chlorella elliposoidea (Gerneck) + Scenedesmus bijuga (Turpin) Lageh as prevention and biological control treatment of cyanobacterial blooms as field application.
Are fishers poor or vulnerable? Assessing economic vulnerability in small-scale fishing communities
Type: Journal Article
An index of economic vulnerability is developed and used with a more conventional measure of income poverty to explore vulnerability and chronic poverty in isolated rural communities. The method is applied to data from ...
A viability analysis for a bio-economic model
Type: Journal Article
This paper presents a simple dynamic model dealing with the management of a marine renewable resource. But instead of studying the ecological and economic interactions in terms of equilibrium or optimal control, we pay ...
Spatial patterns of epilithic algal and detrital resources on a windward coral reef
Type: Journal Article
Algae and detritus co-occur on reef substrata, but their relative importance to consumers, in terms of biomass and nutrient content, is poorly understood. Epilithic algae, sediment and detritus were sampled among four ...
Towards the index of all known species: The Catalogue of Life, its rationale, design and use
Type: Journal Article
The Catalogue of Life, created by Species 2000 and the Integrated Taxonomic Information System, has the ambitious aim of creating a uniform and validated index of the world’s known species for use as a practical tool in ...
Investment Appraisal of Genetic Improvement Programs in Nile tilapia (Oreochromis Niloticus)
Type: Journal Article
The economic benefit derived from a genetic improvement program with Nile tilapia (Oreochromis niloticus) was examined from a national perspective. An industry structure was assumed whereby the genetic improvement program ...
