A study of the sand crab (Portunus pelagicus) and its exploitation in a sub-tropical multi-sector fishery

Based on logbook records the sand crab commercial pot fishery in Moreton Bay is worth in the vicinity of $2 million wholesale annually. Sand crabs are also taken as an incidental by-catch by otter trawlers and in addition Moreton Bay supports a substantial recreational fishery. Sand crabs are caught...

Revolutionising fish ageing: Using Near Infrared Spectroscopy to Age Fish

Results from the current ‘proof of concept’ study indicate that near infrared (NIR) spectra collected from fish otoliths have potential to estimate the age of Barramundi (Lates calcarifer) and Snapper (Pagrus auratus), with performance varying between species and locality of capture. A...

Objectives

1. Identify the main clupeoid species accessible in South-East Queensland and experimentally determine the seasonal abundance of these species.
2. Define size and age structure and examine the reproductive cycle of the major small pelagic species present in South-East Queensland.
3. Estimate egg densities and spawning biomass indices of the small pelagic clupeoid species present in South-East Queensland waters.
4. Examine methods of estimating potential fishery yields for a limited purse seine fishery in South-East Queensland.
5. Examine the species composition from experimental purse seining in South-East Queensland and comment on areas of possible conflict with other users.
6. Examine the potential impact of developing and existing purse seine fisheries on predator species.

Informing inter-jurisdictional snapper management in eastern Australia

Snapper has been fished since the early development of the colony around Sydney Harbour in the late 18th century, but it was the arrival of steam power in the 1860’s that enabled fishers to start regularly targeting the abundant schools of snapper occurring in the deep-water fishing grounds...

Impoundment stocking strategies for eastern and northern Australia

Fish stocking is a valuable and widely used fisheries management tool. If managed well, a fish stocking program can improve the status of declining or threatened fish stocks, restore species diversity to a degraded waterway, and even create a fishery where there was none before. The positive image...
