Seychelles has a well-developed fishing sector that is a vital part of the social and economic development of the country. Three main types of fisheries are recognised: artisanal fisheries targeting demersal and semi-pelagic species, semi-industrial fisheries targeting pelagic species, and industrial fisheries targeting species of tuna. In economic terms, the industrial fisheries are of greatest importance. The per capita consumption of fish in Seychelles is one of the highest in the world and the artisanal fisheries contribute significantly to the protein requirements of the country. Artisanal fisheries catches have remained fairly stable since comprehensive monitoring began in 1985, averaging 4568 MT per annum. A wide range of fish and invertebrate species are targeted and the general catch composition has remained stable. Landing of tuna by the purse seine fleets has grown substantially over the last 18 years, attaining a record catch of approximately 42 945 MT in 2002. The demersal stocks targeted by the artisanal fisheries are known to be over- or optimally exploited close to centres of population, and lightly exploited elsewhere, whilst the industrialised fisheries for pelagic species require a precautionary approach to management as some stocks are being exploited close to maximum sustainable yield levels. Future development in Seychelles is tightly linked to fisheries and the marine environment in general.

Unlike most rivers globally, nearly all lowland Amazonian rivers have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate seasonally into floodplains, favoring expansive floodplain areas. Frugivorous fish are forest-dependent fauna critical to forest regeneration via seed dispersal and support commercial and artisanal fisheries.

Objective: Marine fishing ranks among the most hazardous occupations globally, with risks intensifying for small-sized vessels venturing deeper into the sea due to the scarcity of near-shore fish and high market demand. This study identifies various occupational hazards and the use of safety equipment among small-scale motorized fishers using traditional fishing methods in the southernmost coastal regions of India.
Methods: The primary data were collected from 253 artisanal small-scale motorized fishers through a multi-stage stratified random sampling method.

Small-scale shrimp trawling is crucial for the economy and culture of coastal communities worldwide, providing several ecosystem services. However, bottom trawling is well-known for its negative impacts on habitat structure and marine communities. Bycatch, or the accidental capture of non-target species during fishing, can offer valuable insights into the composition and variation of fish assemblages.

The present study provides a comprehensive overview of the taxonomic diversity of flatfish in Indian waters. Flatfish play a significant role in artisanal and commercial fisheries in India and are frequently caught as by-catch in trawling operations. However, their benthic nature makes them particularly vulnerable to the pressures of overfishing and bottom trawling practices.
