Summary

Most marine and freshwater fishes depend on plankton for food during a period shortly after birth until they are large enough to switch to other prey. At the Inland Fisheries Research Station, Narrandera (NIFRS), native fish are spawned and the larvae transferred to rearing ponds for approximately six weeks before the fingerlings are harvested. These ponds are managed to promote growth of the appropriate zooplankton so that the larvae can feed and grow.

Four larval rearing ponds were studied from when they were filled in early November 1986 until just before harvesting in late December 1984.

Summary

Since the spread of common carp into South Australia in the early 1970's, they have remained abundant in the River Murray and the lower lakes. With the continued high catch rates, there has been concern as to the effects carp may have on the environment and on native fish. This impact will be determined largely by the feeding habits of carp. Although carp are recognized as the most widely distributed freshwater fish, very little is known of their ecology in natural environments. overseas studies have suggested that carp feed by 'roiling' the mud and selecting food particles from the suspended matter. This study aimed to determine the diet of carp in Lake Alexandrina and to make inferences on the environmental effects carp may produce.

Minor use permit for oxytetracycline in non-salmonid finfish

There are no registered or permitted antimicrobial products approved by the Australian Pesticide and Veterinary Medicine Authority (APVMA) for treatment of bacterial infections in finfish. This project developed an application for a minor-use permit (MUP) for the use of oxytetracycline (OTC) to...
