Adult reproductive data for redbait is based on collections taken by midwater trawling during the spawning season and includes the biological information - size, sex, reproductive condition (weight and stage). Histological examination of mature ovaries provides information on spawing activity and preserved gonads are examined to determine batch fecundity.

Between January and March 2003, 25 (15 females, 9 males, 1 no sex recorded) draughtboard sharks, sourced from the Crayfish Point Reserve and the east coast of Tasmania (42-43°S, 147-148°E), were fitted with the acoustic transmitters to investigate movement behaviour.

This data represents research conducted as part of a PhD project on Striped Trumpeter (Latris lineata). Recorded the prevalence of Kudoa neurophila (a myxozoan parasite formerly known as Pentacapsula neurophila) in relation to age for hatchery reared Striped Trumpeter using histology and PCR testing. Histology and in situ hybridisation techniques were incorporated into the study of the histopathology of the disease caused by this parasite to elucidate its entry point on the fish host and migratory pathway to terminal stage sporulation.

Landings surveys of bycatch of Solegnathus assessed from interviews with fishers in important fishing ports of NSW and Victoria, ranging from the Brunswick-Byron co-op to Portland in Victoria.

A single database has been implemented to store catch sampling and targeted research data collected since the late 1990s. In addition, data for key species e.g. striped and bastard trumpeter, has been uploaded from historic data bases to provide a complete dataset for the key species. Commercial catch sampling plus opportunistic collections of key scalefish species provide size and age structure information for catches. Where feasible additional biological information e.g. sex and reproductive status is collected.

This data represents research conducted as part of a PhD project on Striped Trumpeter (Latris lineata). Knowledge of the microbial bacterial community of the larvae, seawater and live feeds is necessary in order to develop an understanding of what represents a healthy microbial ecology relevant for larval fish rearing success. 16S ribosomal RNA (rRNA) gene-based clone library and terminal restriction fragment length polymorphism (TRFLP) analyses were utilized to examine the microbial community associated with larvae cultured under different “greenwater” conditions and determine the success of probiont application in live feeds used for larval fish rearing. Though water quality was apparently influential on larval survival, no specific bacterial species present either on the larvae or in surrounding tank water could be attributed to reduced survival. Two bacterial strains, Pseudoalteromonas sp. ST8 and Vibrio sp. ST7 were found to inhibit bacteria pathogenic to larval fish through production of extracellular substances. Strain ST8 was found to be compatible with artemia, rotifers and larval fish and outcompeted the fish pathogen Vibrio proteolyticus in competition experiments. Encapsulation experiments indicated strain ST8 was transferrable to artemia and thus represent a potential probiont for larval fish mariculture.

This data represents research conducted as part of a PhD project on Striped Trumpeter (Latris lineata). Recorded taxonomy of copopod parasites and investigated potential treatments over the lifecycle of two parasites: caligus and condracantha, in hatchery reared Striped Trumpeter.

The data is quantitative abundance of fish and megafaunal invertebrates and algal % cover derived from transect based counts at a wide range of locations across Temperate Australia. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. Methods were initially developed for research on temporal changes following protection in Tasmanian MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island). Further research has collected data in Tasmania, in MPA planning surveys (e.g. St Helens, Waterhouse Region, Low Head, Lillico Beach, Rocky Cape), an oil spill assessment (Low Head), and in studies and surveys in new Tasmania MPAs (Port Davey and the Kent Group). The data represented by this record was collected in MPA planning surveys and for opportunistic surveys such as the Low Head oil spill assessment. In many cases the dataset involved temporal replication (year scale).

Data is primarily fish health reports for hatchery reared striped trumpeter (Latris lineata), including issues relating to bacterial (vibrio), viral (particularly noda virus) and parasitic (parasitic copopods and kuoda) infections. Also included is information on the taxonomy and treatment of parasites.

Between January 2000 and January 2007, sharks were tagged during routine fishery dependent and independent rock lobster catch sampling trips around southwestern and eastern Tasmania and in the Crayfish Point Reserve. For each shark, sex, total length and clasper length (males) were recorded.
