In this chapter, we review in detail the existing body of literature and knowledge related to the provision of food in estuaries and coastal zones. Both aquatic and terrestrial commodities are considered. The chapter highlights not only the importance of the terrestrial zone in overall food provision but also the substantial contribution of aquatic coastal resources. The various problems that the coastal zone faces in sustaining this important provisioning service in the face of increasing pressure and demands from other sectors are highlighted.
The present paper introduces a new method for data gathering using digital tablets in the field. The method is part of a fisheries study aimed at identifying migration patterns and breeding sites of key commercial fish species in Myanmar. The research is based on systematic and structured gathering of local knowledge along a 1,000 km long segment of the Ayeyarwady River, from the southern Delta to the northern Central Dry Zone. Digital tablets are used to convert local indigenous knowledge into data.
Southeast Asian lowland rivers are among the longest and most productive rivers for wild-capture inland fisheries in the world. They have many elements in common: they mostly arise on the Tibetan Plateau and have steep and turbulent upper courses within deep mountain valleys and flat lower courses associated with large deltaic wetlands. Their lower basins are now densely inhabited.
The authors discuss how the fisher community and the government shared responsibility over time for regenerating and conserving fishery resources in San Salvador Island, Philippines, and rose above the obstacles associated with a de facto open access fishery. The article highlights the creation, management, and impact on ecosystem health, both natural and human, of a marine reserve and sanctuary. It examines key events and arrangements during three distinct phases: pre-project (before 1989), project phase (1989-1993), and post-project (1994-1998).
An overview of FishBase and SeaLifebase was given.
Cambodian inland fish resources are part of the Mekong system. With 781 known freshwater and brackish fish species, the Mekong Basin has the second highest fish biodiversity in the world after the Amazon Basin in South America. Cambodia itself features 461 freshwater species, plus 468 marine species and 26 species found in both environments. This makes 955 fish species in total.
The Republic of Kiribati is a vast South Pacific island group with one of the largest exclusive economic zones (EEZs) in the world. Kiribati waters support a wealth of marine fisheries activities. These activities occur in oceanic, coastal and inshore environments and range from large, foreign, industrial-scale oceanic fishing operations to small-scale, domestic, inshore subsistence fisheries, aquaculture and recreational fisheries.
In this review, the author provides an overview of the small water bodies as an important inland fishery resource and analyses the global trends in their utilization. He also assesses the opportunities for enhancing fish production from these water bodies based on the strengths and weaknesses of the different management options.
A mass-balance model of the trophic structure of San Pedro Bay, Leyte Province, Philippines was constructed using the Ecopath modeling software. The model is composed of 16 ecological groups (13 consumer, 2 producers, 1 detritus groups). The input parameters were obtained from the resource assessments studies conducted in 1994 - 95 and the biomass of Leiognathidae, an important group of small demersal fishes was estimated from trawl survey data using the swept- area method. The model indicated that the average trophic level of the fishery catches is 3.25.
Demersal surveys from the southwest coast of India were analyzed to determine the general pattern of distribution of demersal species assemblages in the area. Seasonality is pronounced, indicating three major periods, pre-monsoon, monsoon and post-monsoon. Each of the periods is characterized by different oceanographic circulation patterns that mainly determine the pattern of distribution of species assemblages. Spatial analysis confirmed that the Wadge Bank has the highest potential for producing good quality fish.
