Fisheries management papers
This discussion paper has been prepared by the Department of Fisheries (Western Australia) to address the issue of recreational collection of coral in coastal waters of Western Australia. The paper describes: • popular coral locations in WA; • management issues associated with the recreational collection of corals; • management objectives and strategies as possible options to address the issue of recreational collection of corals; and • seeks public input on the proposed management objectives and strategies.

Monitoring Defecation Activity Of Infaunal Deposit Feeders, Fred C. Dobbs

An inexpensive, reliable thermistor device capable of monitoring infaunal foraging activity was built and used in the laboratory to examine effects of temperature on sediment reworking by the maldanld polychaete Clymenella torquata. The worm defecated at least once per hour 55.0 % (12.0 "C) to 88.2 % (5.5 "C) of the time. Defecation rate was linearly and positively related to temperature. Estimated volume of sediment ejected per defecation (0.015 ml) did not change with temperature. Results are compared with previous reworking studies of C. torquata.
