Development of alternative fishing practices for the harvesting of wild and re-seeded scallop beds in Tasmania

OBJECTIVES: a. To determine the efficiency of Beam, Triple and Prawn trawling methods for the harvesting of scatlops. b. To investigate the difference in efficiency between the sputnik dredge and the Japanese Keta-ami dredge. c. To investigate the difference in bottom damage between the sputnik and...

Objectives

1. Carry out assessments of oyster production in relation to primary productivity and nutrient cycles in five or six coastal areas used for oyster ongrowing and fattening in Tasmania
2. To develop predictive models of the carrying capacities of these areas
3. To utilise these models in the formation of a general model which can be applied with specific minor modifications to existing and potential intensive shellfish farms
4. To apply this general model in the day-to-day shellfish farm management

Assessment of demersal fish resources of the south western sector

Catch statistics for 13 species from commercial and research trawls conducted between 1979 and 1984 in the southern areas of the South-East Trawl fishery are examined. Catch and catch per swept area from demersal trawls were stratified by position, depth and month and shots were subsequently...

Using scat DNA to inform sustainable fisheries management and Ecological Risk Assessments: a Shy Albatross case study

Seabirds are attracted to fishing vessels through the availability of fishery discards, increasing the risk of injury or mortality from interactions with fishing gear. However, it is difficult to estimate what proportion of the population may be at risk. We use DNA metabarcoding of scats to...
