Assessment of optimal trapping techniques to control densities of northern Pacific seastars on marine farm leases

The principal aims of this study were to evaluate whether the locally­ produced Whayman-Holdsworth trap provides an effective method for minimising Asterias amurensis infestations on shellfish farms, and to objectively assess the value of seastar traps when used in commercial applications. In an...

Need

The Molecular Biology group at the Animal Health Laboratory of the Department of Primary Industries, Parks, Water & Environment, provides diagnostic and disease investigation services for aquaculture industries in Tasmania. The increasing reliance on molecular techniques for the detection and identification of disease agents in aquatic animal health is undeniable. Due to the ever increasing number and more efficient molecular techniques becoming available and the dynamic nature of newly emerging pathogens, specialist training is increasingly important for the delivery of effective and useful services to aquaculture. Presently, species identification relies heavily on biochemical tests and cellular fatty acid analysis, or 16S rDNA gene sequencing, all of which at times can be non-definitive. Multi-locus sequence analysis uses several housekeeping genes to assign a species designations, and is a technique that is easy to use, accurate, and has great discriminatory power (McTaggart et al., 2010). The multi locus sequencing skills acquired would enable us to more specifically and accurately perform species identification and determine genetic diversity among different isolates and build up a gene bank of sequences in the future.

Objectives

1. Obtain training in advanced molecular biology techniques with an emphasis on DNA sequencing and phylogenetic analysis at a known international specialist laboratory
2. Undertake training in bioinformatics programmes with an emphasis on Multilocus Sequence Analysis (MLSA) at a known international specialist laboratory

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...

The second international symposium on abalone biology fisheries and culture

The First International Symposium on Abalone Biology, Fisheries and Culture was held in La Paz, Mexico in November 1989. In the closing session of that symposium it was decided to hold the second abalone symposium in Australia in 1993 or 1994. Subsequently, Hobart was chosen as the site and 7-11...
