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.

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.

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.

In Tasmania, SCUBA surveys of seahorses populations were conducted. Intensive surveys were conducted in 2000 to 2004 in the Derwent River around Hobart (submonthly & then monthly) and twice yearly surveys from 2004/5 on east coast and Derwent River, until 2007. Mark-recapture studies were done to estimate population size, and life history parameters.

Database contains information on eggs and larvae of redbait (Emmelichthys nitidus) collected during surveys conducted around eastern to south-western Tasmania in October 2005 and 2006. The database also contains details of each sampled station (e.g. depth, Lat, Long, sampling time) as well as information on the volume of water sampled by each net which is needed to estimate relative abundance of eggs and larvae (numbers per metre square). A separate database contains all data of physical variables recorded by depth simultaneously with each sample, including temperature and salinity.

Sampling of commercial mid-water trawl catches for small pelagics from waters adjacent to Tasmania have yielded an extensive biological dataset in space and time. As a minimum, size composition information is available from most commerical shots undertaken between 2002 and 2006, referenced with operational information (location, depth and catch weight). Subsamples of the key small pelagics, redbait, jack mackerel and blue mackerel, were examined for size, sex, gonad weight and stage and otoliths have been retained for age determination. Further data has been collected since the initial investigation.

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.

SCUBA surveys and mark-recapture of seahorse populations in Sydney Harbour using visible implant fluorescent elastomer.

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.

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.
