BACKGROUND Lymphocystis disease (LCD) is the main viral infection reported to affect cultured gilthead seabream (Sparus aurata) in Europe. The existence of subclinical Lymphocystis disease virus (LCDV) infection in this fish species has been recognised by using polymerase chain reaction (PCR)-based methods. Nevertheless, these methods do not provide quantitative results that can be useful in ep...

In the Mekong delta, inland fishing and rice production provided a major source of income for rural communities. Since early settlement, the inhabitants have caught fish. Still, fish provides the main source of animal protein in their daily diet (Madan et al. 2005). Fish are caught in flood plains and in rice fields. The wild fish catch has declined since 1970 (Gagauan & Arce 1992), as a result...

Sediment dynamics and the hydrodynamics of the environment cause the complexity and variability in animal-sediment relationship, both in spatial and temporal. This study is focused on the response of macrobenthic fauna to environmental disturbance caused by fish farming using their trophic structure. Their changes in trophic structure can be used as an indicator of disturbance. Eight control si...

This publication is designed to help individuals interested in aquaculture gain a better understanding of the challenges involved in establishing a successful fish farm. Although most information here applies to traditional freshwater aquaculture, readers interested in marine culture systems and specialty type aquaculture will be able to glean useful information. A glossary, included at the end...

This article reports the most frequent cases of poisoning in farm animals, horses, cats, dogs, wild animals, fish and honey-bees in the Czech Republic. At present, there are fewer cases of acute poisoning caused by high doses of toxic substances but there are more and more cases of chronic poisoning as a consequence of environmental pollution.

CONTEXT The consumption of fish high in omega-3 fatty acids is advocated by the American Heart Association to decrease the risk of coronary artery disease. However, fish contain environmental toxins such as mercury, polychlorinated biphenyls, and organochlorine pesticides, which may negate the beneficial cardiovascular effects of fish meals. Toxin levels vary depending on both the fish source a...

The prevalence of allergy is markedly low in children growing up on farms. An increasing number of studies indicate that the timing of food introduction may affect allergy development. We aimed to investigate if protection against allergy in farm environments may be mediated through differences in food-introduction practices between farm and non-farm families, using an explorative approach. Twe...

Philip Lymbery is an international animal welfare consultant. In 1992, his report, The Welfare of Farmed Fish, was the UK's first to look at the welfare issues in salmon and trout farming. This was written whilst working for Compassion In World Farming (1990-2000), where he spent the last 7 years as Campaigns Director. Maintaining a special interest in fish welfare, Philip submitted both writte...

Sparus aurata larvae infected by viral nervous necrosis were collected from an aquaculture fish farm. The isolated viral genome, composed of two segments (RNA1 and RNA2), was sequenced and analyzed comparatively. Phylogenetic tree analyses revealed that the isolated strain is a reassortant, exhibiting a red-spotted grouper nervous necrosis virus (RGNNV)-type RNA1 and a striped jack nervous necr...

Streptococcus agalactiae is an important pathogen to world aquaculture due to its high mortality rates in fish farms and consequent economic losses. Our study presents the complete genome sequence of strain S13, isolated from a tilapia farm outbreak in southern Brazil.
