Commercial coral reef fisheries in Pohnpei (Micronesia) extract approximately 1,521 kg of reef fish daily (~500 MT year-1) from 152 km2 of surrounding reef. More than 153 species were represented during surveys, with 25 species very common or common within combined-gear catch. Acanthurids contributed the greatest to catch volume, with bluespine unicornfish, Naso unicornis, and orangespine unicornfish, Naso lituratus, among the most frequently observed herbivores. Nighttime spearfishing was the dominant fishing method and inner lagoon areas were primarily targeted.
Between 1999 and 2003, the WorldFish Center in Solomon Islands conducted research into the feasibility of a new fishery based on the capture and culture of postlarval coral reef fish for the live fish trade. The work was carried out in two phases: a research phase from late 1999 to the end of 2002; and a “finetuning” phase in 2003. Most of the species were of value to the marine aquarium trade, with very few live reef food fish recorded. The most valuable ornamentals were the banded cleaner shrimp, Stenopus species.
The purpose of this project has been to address the issue of decreased catch rates and declining income per unit of fishing effort in Jamaica's artisanal fisheries. This is an issue that is not unique to Jamaica. It is faced by fishers in most of the countries surrounding the Caribbean. The absence of any significant fisheries management, combined with excessive population densities and a lack of employment opportunities, has led to increasing fishing effort in Caribbean coastal fisheries, resulting in recruitment and growth overfishing.
The information presented in this volume was first published in 18 mimeographed parts over the period 1973-1981 as Number 3 in the series Research Reports from the Zoology Department, University of the West Indies. The full series is now reprinted by ICLARM, with the permission of all contributors, as a single volume. An epilogue reviewing progress in coral reef fisheries research over the period 1973-1982 has been addedfrom which it is possible to make some appraisal of the accuracy of the original parameter estimates.
This workshop and the resulting proceedings came into being as a result of cumulative concerns by aid agencies, nongovernmental organizations and by government authorities and researchers on the mass installation of artificial reefs in the Philippines. Artificial reefs are usually constructed from materials such as scrap tires, metals, concrete blocks, bamboo and nondegradable synthesis such as polypropylene rope. What are their environmental impacts?
This study highlights the potential role of artificial reefs in Coastal Resource Management in the ASEAN region. It discusses the considerations necessary to maximize the effectiveness of artificial reefs as a means for fisheries management and habitat enhancement. It illustrates many practical examples of how artificial reefs have been used effectively and what are their limitations.
A review of the fishery in the Gulf of Thailand is presented which notes that the current level of trawling effort is excessive and suggests that a substantially lower trawling effort would probably improve the total economic value of the catch by reducing the proportion of trash fish in the catch and increasing the proportion and size at landing of fishes with high commercial value.
Coral reefs, the storehouses of much of the world’s marine biodiversity, and the source of many socioeconomic benefits, are in decline worldwide. The causes of the ‘coral reef crisis’ are complex but there is general agreement that two broad categories of stress are involved: global-scale climatic changes induced by production of greenhouse gases, and local-scale impacts.
This poster shows that coral reefs are a vital source of food and income for coastal communities and protect the coast from storm. Hence it is important that they are to be protected.
