Tilapia farming in Kuwait is in its early stages. Slow growth, high production cost and poor demand are the major constraints to the expansion of tilapia culture in Kuwait. This article presents some suggestions for overcoming these problems to improve the economic feasibility of tilapia culture in Kuwait.
This paper is based on a first phase of a study in the Muthurajawela-Negombo wetland complex and aims to assess the overall spatial linkages between ecological and socioeonomic aspects of the wetland system using a geospatial model; incorporating biophysical and socioeconomic parameters for analysing and modelling the changes in the coastal wetland-agriculture-aquaculture complex.
Aquaculture now contributes nearly half of the global food fish production and, by the year 2030, estimates are that an additional 27 million tonnes, or over 50 percent from the current production, will be needed to meet the growing demand for food fish. This article summarises the role aquaculture plays in contributing to the global food supplies and highlightes the related economic benefits.
In the past 50 years, the turbot is referred to either as Scophthalmus maximus (Linnaeus, 1758) or Psetta maxima (Linnaeus, 1758) in the literature. Norman (1931) had argued that the valid name for the turbot was Scophthalmus maximus. However, his recommendation was never universally accepted, and today the confusing situation exists where two generic names are still being used for this species. We address this issue by analysing findings from recently published works on the anatomy, molecular and morphological phylogenetic systematics, and ecology of scophthalmid fishes.
Sandfish is arguably the most commercially valuable of the tropical species of sea cucumber that are processed into bêche-de-mer. It is widely distributed throughout the Indo-Pacific, occurring in shallow inshore areas where it is easily accessible to coastal fishers. A-grade bêche-de-mer processed from sandfish commands some of the highest prices on the international market. But these same attributes also make it vulnerable to overexploitation. Sadly, this has happened in most places where it occurs.
Results of the study on the relative safety of nine different pesticides: Diazinon 40% EC, Diazinon 10 G, Elsan 50% EC, Sumithion 50% EC, Furadan 3 G, Padan 50% SP, Kitazin 48% EC, Kitasin 17% G and EPN 45% EC for various fish species: Cyprinus carpio, Labeo rohita, Oreochromis mossambicus, Channa punctata, Clarias batrachus and Anabas testudineus used in rice-fish culture are presented and discussed.
Goldfish, common carp and Nile tilapia were sampled between September 2002 and May 2003 to investigate lesions induced by viral diseases and ectoparasites. Goldfish exhibited neoplasms, Dermocystidium sp., Ichthyophthirius multifiliis (Ich), Trichodina reticulata, Lernaea cyprinacea and systemic infections. Neoplastic and systemic infections in goldfish were associated with viral infection. Oreochromis niloticus and Cyprinus carpio were mainly infested with several species of Trichodina and monogeneans. The presence of Dermocystidium sp.
The WorldFish Aquaculture Research and Training Center is located outside Abbassa, a typical village in Egypt's Nile delta. The WorldFish Center launched its regional research and training activities in 1998. Courses were held in the center from 1999 to 2009. The growth in training over this period reflects the growth in aquaculture in Egypt and globally, the need for trained technicians, and the growing reputation of the Center in this field.
This review is prepared as part of the FAO Project “Environmental Impact Assessment (EIA) and monitoring in aquaculture”. The review provides a compilation, review and synthesis of existing EIA and environmental monitoring procedures and practices in aquaculture in the Asia-Pacific region, the largest aquaculture-producing region in the world. This review, as in other regions, gives special consideration to four areas related to EIA and monitoring in aquaculture including: (1) the requirements (2) the practice (3) the effectiveness and (4) suggestions for improvements.
