Exposure to pesticides remains a major environmental health problem. Health risk from such exposure needs to be more precisely understood. We conducted three different cytogenetic assays to elucidate the biological effects of exposure to mixed pesticides in 20 Costa Rica farmers (all nonsmokers) compared with 20 matched controls. The farmers were also exposed to dibromochloropropane during the ...

This paper is focussed upon the emergent emphasis of environmentally friendly (ENVF) attributes in fish with particular regard to tilapia in the UK. The focus is upon the technical production issues, marketing implications, public health and adoption responses from a 3 years multidisciplinary Research Councils UK project which examined the prospects for UK (agricultural) farmers to diversify in...

We examined how traditional farmers preserve the genetic diversity of a local common carp (Cyprinus carpio), which is locally referred to as "paddy field carp" (PF-carp), in a "globally important agricultural heritage system" (GIAHS), i.e., the 1,200-y-old rice-fish coculture system in Zhejiang Province, China. Our molecular and morphological analysis showed that the PF-carp has changed into a ...

Salmon lice causes reduced fish welfare as well as great economical losses along with a significantly increased amount of work for fish farmers. Resistance among salmon lice to well established treatments has resulted in repeated treatments and reduced immune systems among the fish. The main focus of this work is to investigate correlations between salmon liceand treatment-data received from a ...

This study was conducted in cage aquaculture villages in Hongngu District, Dong Thap Province of Vietnam during November 2001 to November 2002. Cage culture areas are located in the confluence of So Thuong Canal and one branch of the Mekong River. The purposes of this study were to investigate the cage culture system and its related environmental conditions, to determine the quality and quantit...

We evaluated the status of Clonorchis sinensis infection and potential risk factors among residents of riverside areas (Geumgang) in Muju-gun, Jeollabuk-do (Province), Korea. From January to February 2010, a total of 349 (171 males, 178 females) stool samples were collected and examined by the formalin-ether concentration technique. Also, village residents were interviewed using questionnaires ...

The Peruvian Amazon is in an advantageous situation for fish culture. Survey data from 146 practicing fish farmers show that they culture a variety of species, but regardless of the kind of fish they grow, farmers view fish culture in a positive light. While gamitana (Colossoma macropomum) is not the only Amazon fish to deserve special attention, it is the first species about which enough is kn...

Because rice feeds half of the world's population, a secure global food supply depends on sustainable rice production. Here we test whether the co-cultivation of rice and fish into one "rice-fish system" (RFS; fish refers to aquatic animals in this article) could help sustain rice production. We examined intensive and traditional RFSs that have been widely practiced in China. We found that rice...
