This paper highlights the importance of fisheries and aquaculture in management of the world’s water resources. It underlines the value of these resources and the critical importance of managing water quantity and quality for fisheries and aquaculture as well as for other human uses. This will require more holistic approaches to water management and the effective governance systems these require.
Issues concerning the promotion of wastewater reuse in aquaculture are re-examined in this article.
Ce rapport présente les activités et les résultats de l’atelier Vision 2050: Changement climatique, pêche et aquaculture en Afrique de l’Ouest. Les objectifs de l’atelier étaient de discuter les questions critiques et les incertitudes auxquelles est confronté le secteur de la pêche et de l’aquaculture au Ghana, au Sénégal et en Mauritanie, d’élaborer des scénarios sectoriels pour 2050 et de discuter de l’implication de ces scénarios dans le contexte du changement climatique pour ces pays et la région ouest africaine.
Worldwide, there are many substantial coastal aquaculture and stock enhancement operations based on collection of wild juveniles. These include: growout of shrimp (Penaeidae), milkfish (Chanos chanos), eels (Anguilla spp.), yellowtail (Seriola quinqueradiata), southern bluefin tuna (Thunnus maccoyii), edible oysters (Ostreidae) and mussels (Mytilidae); stock enhancement of scallops (Pectinidae); and the culture of pearls in farmed blacklip pearl oysters (Pinctada margaritifera). The growout of wild puerulus larvae of spiny lobsters (Palinuridae) is also developing rapidly.
This paper attempts to review the use of antibiotics in aquaculture in Malaysia because of the heightened concerns over its use and abuse and its impact on human health and the environment. Health and environmental issues relating to antibiotic use and measures that can reduce or control the impacts are also discussed.
The production of snakeskin gourami (Trichogaster pectoralis) from wild stocks and traditional culture systems has been declining in central Thailand, although they are on the increase in modern culture practices adopted in some provinces. Net yields of T. pectoralis in traditional systems are about a third of those in modern systems. The potential of T. pectoralis as a candidate for more intensive waste-fed polyculture appears promising if seed supply constraints can be removed.
Over 5 years of participatory on-farm research, market access, profitability, farming systems productivity and economic sustainability were compared on 100 small-scale farms in Central Cameroon. Integration technology based on the use of agricultural by-products as fishpond inputs was the driver for intensification. Over all farms, fishpond productivity increased from 498 kg to 1609 kg fish/ha (2145 kg/ha/yr). During the project period, the number of active fish farmers increased from 15 to 192 (including 55 farms which participated only through information exchange).
Based on the selected case studies from various chapters in the book "Success stories in Asian aquaculture", this chapter further examined the broader set of lessons learned around successes in aquaculture in Asia with the aim of developing improved guidance or influencing strategies around possible steps to follow; steps in the further development of this set of ideas, and in the sector as a whole.
The Strategy on International Fisheries Research's activities on information and aquaculture in Asia, SubSaharan Africa, Latin and North America are presented.
