Abstract

Most captive fish eating animals are fed frozen, thawed fish that are received in bulk and stored for a period of time before being prepared by cutting prior to feeding. Given the perishable nature of fish, appropriate handling is crucial to minimize nutrient loss and bacterial load. Fish should be supplied from fisheries that have caught, processed and stored the fish as if it were intended for human use. Guaranteeing that the supplier utilizes a Hazard Analysis and Critical Control Point (HACCP) program can help ensure that fish supplies have been handled appropriately prior to receipt.4,5 Every lot of fish should be inspected before paperwork is signed and the load is officially received. Once accepted, fish should be placed immediately in the institution's storage facility. It is recommended that fish stored for prolonged periods should be in a freezer maintained at -23°C or lower. Fish should be thawed under refrigeration, never at room temperature and kept refrigerated until fed to the animals.3 Equipment used for holding, thawing or preparing fish must be cleaned and sanitized daily.3 In order to ensure that conditions are appropriate and methods for storage and handling fish are proper, validation of conditions and procedures is necessary. Fish can be sampled for microbial buildup of a number of specific organisms at various stages of thawing and handling.1 Fish should also be sampled for nutrients, toxins and heavy metals. A pamphlet is available that details these standard operating procedures.2
