Safety on North Carolina and Kentucky trout farms.

The objective of this study was to identify and describe work-related safety hazards, injuries, and near-injury events (close calls) that occurred on trout farms in North Carolina and Kentucky. An interview instrument was used to collect information on occupational hazards, injuries, and near-injury events that resulted from work-related activities. Trout farmers reported occupational hazards including falling live tank lids, slippery surfaces on hauling trucks, lifting strains, falls from raceway walls and walkways, needlesticks while vaccinating fish, allergies, hypothermia/drowning, falls from cranes, chemical exposure, fire/explosions related to oxygen exposure, and electrical contact with overhead power lines.

Health and safety concerns in fisheries and aquaculture.

Only 10% of all foodborne illnesses in the United States are attributed to seafood, making seafood a relatively safe food commodity. The implementation of Hazard Analysis and Critical Control Points guidelines should make seafood consumption even safer. Concerns include closed-loop, indoor, water-recirculating production systems; harmful algal blooms in marine environments, which can cause paralytic, neurologic, amnesic, and diarrhetic shellfish poisonings and ciguatera fish poisoning; bacteria (such as Mycobacterium marinum and Streptococcus iniae) and nematode, cestode, trematode, and protozoan parasites found in fish that cause human infections; and the shellfish origin of Norwalk virus infection.

Fish mortality in the Mississippi catfish farming industry in 1988: causes and treatments.

The 1988 fish mortality summary for the catfish (Ictalurus punctatus) industry in Mississippi is presented. In 1988, 2,456 cases were submitted to Mississippi Cooperative Extension Service fish disease laboratories at Belzoni and Stoneville. Bacterial infection caused by Edwardsiella ictaluri was the leading cause of catfish mortality.

Interaction of bass tapeworm, Proteocephalus ambloplitis, and Neoechinorhynchus sp. (Acanthocephala) in largemouth bass, Micropterus salmoides.

The number of plerocercoids of the bass tapeworm, Proteocephalus ambloplitis, in wild largemouth bass was negatively correlated (r = -0.94) with the number of Neoechinorhynchus sp. Competitive inhibition between the 2 parasites appeared to exist.

Severed intestine in channel catfish.

Six cases of severed intestines in farm-raised channel catfish were examined at fish disease diagnostic laboratories in Mississippi and Alabama. This condition has not been reported previously in fish. Affected fish had a 4-7-cm-long intestinal section (hyperemic where it was severed) attached to the stomach.
