Seafood CRC: dynamics of growth in translocated lobsters

Project number: 2014-725
Project Status:
Completed
Budget expenditure: $18,307.00
Principal Investigator: Caleb Gardner
Organisation: University of Tasmania (UTAS)
Project start/end date: 13 Apr 2015 - 30 Sep 2015

Need

The project will produce three papers related to growth of translocated rock lobsters. These are not critical for current operations which are locked in for a three year period. However they may be important for addressing industry concerns when the operations are next voted on in 2016. Aside from that need they maximise the benefit from investments into research on translocation of rock lobsters over the last decade.

Paper 1. Growth compensation in lobsters moved inshore
Paper 2. Density dependent changes in lobster growth
Paper 3. Fine scale variation in growth off western Tasmania

Objectives

1. Complete three papers dealing with growth of rock lobsters to enable improved outcomes from translocation.

Seafood CRC: addressing roadblocks to the adoption of economics in fisheries policy (2013/748.20 Communal)

This project has led to the development of three journal articles examining how the use of economic analyses and stock enhancement can lead to improved economic outcomes in Australian wild-capture commercial fisheries. The Seafood Cooperative Research Centre (Seafood CRC) Future Harvest (FH)...

Dependence of commercially import fish on krill as a food source in south-east Tasmania

This final report on the project describes data on stomach contents of major fish predators of the euphausiid Nyctiphanes australis. The study has concluded that: size and stock of krill and its production can be calculated with some degree of confidence; major predators of adult krill can be...

Impact of gillnet fishing on inshore temperate reef fishes, with particular reference to banded morwong

Project number: 1995-145
Project Status:
Completed
Budget expenditure: $145,513.00
Principal Investigator: Jeremy Lyle
Organisation: University of Tasmania (UTAS)
Project start/end date: 29 Dec 1995 - 30 Jul 1999
:

Objectives

1. Describe life history and population parameters of the key commercial reef fish species.
2. Determine gillnet mesh selectivity for commercial (and by-catch) reef species.
3. Determine the size/age composition of banded morwong populations at different sites off the east coast of Tasmania with particular attention to the impact of differing levels of fishing pressure.
4. Determine patterns of movement for banded morwong, wrasse and bastard trumpeter.
5. Assess the level of by-catch and discarding in the inshore gillnet fishery.
6. Conduct yield per recruit analyses to determine appropriate legal size limits.

Aquafin CRC - Atlantic Salmon Aquaculture Subprogram: establishment of challenge for AGD

This project has increased our knowledge of Amoebic Gill Disease, in particular about the pathogen and the dynamics of infection. We have described a new species of neoparamoeba, Neoparamoeba perurans, and showed that it has been consistently associated with AGD worldwide. Stocking...

Rock Lobster Enhancement and Aquaculture Subprogram: the feasibility of translocating rock lobsters in Tasmania for increasing yield

Translocation involves the shifting of undersize rock lobsters to new areas to increase productivity and/or quality of product. We modelled the translocation of rock lobsters from four original sites to four release sites with a range of growth rates. Most model scenarios led to increases in...
