Recreational Southern Rock Lobster tagging program – assessing current data and modelling assumptions and approaches to establish a robust estimate

This project assesses options for streamlining and improving the current electronic reporting process (VicRLTag app) based on an evaluation of the first three years of the Victorian Recreational Rock Lobster Tagging Program.

Need

This travel bursary application is to attend the 36th annual larval fish conference to be held in Bergen, Norway (2-6 July 2012). The purpose of the conference is to communicate the current state of knowledge around larval fish biology and ecology. Theme sessions focus on mortality in the early life stages of fishes and the contribution of mechanistic behavioural and physiological studies on fish larvae.

The presentation I intend to deliver is 'The effect of ocean warming on the early life history of Latris lineata inferred through a lagrangian bio-physical dispersal model', which fits well into the conference themes. The study species, striped trumpeter is an iconic fish and a popular target of both commercial and recreational fishers. Over 25 years the population has displayed marked recruitment variability. It is thought that this erratic recruitment is due to variability in the success of the early life stages. By combining biological information with oceanographic models we have been able to model the dispersal and survival of this critical life history. We also ran climate change scenarios that predicted the effect of temperature on the survival of this early life stage.

This modelling is likely to develop further into the future, with interest from researchers working on scallops, blue grenadier, southern rock lobster, snapper and long spined sea urchin. By attending the conference I will be able to develop the model further to implement world standard procedures that are realised by discussion and observation of presentations from world leaders in this field.

Objectives

1. Hear presentations from a diverse group of international researchers working on bio-physical modelling of the early life-history stages of fish and invertebrate species
2. Present research on a cutting edge bio-physical model that integrates climate change scenarios and assesses their affect on larval survival
3. Network with peers to enhance the development of bio-physical modelling in Australia

SCRC: SCRC RTG: Collaboration with Dr Salina Parveen to discuss comparisons of Vibrio parahaemolyticus models for Australian Pacific, Sydney Rock, and American Oysters at the University of Maryland (for Mark Tamplin)

Vibrio spp. are bacteria that naturally occur in oysters. Some Vibrio spp. such as V. parahaemolyticus cause human disease when levels are high and oysters are eaten raw. Predictive tools can be used to estimate V. parahaemolyticus levels in oysters, and to monitor and design cold chains that...

Seafood CRC: an evaluation of the options for expansion of salmonid aquaculture in Tasmanian waters

The Tasmanian Salmonid Growers Association (TSGA) strategic plan to 2030 targets a 100% expansion to a $1 billion industry over the next 20 years. The challenge for the Tasmanian Atlantic salmon industry is for sustainable strategic growth. The strategic plan recognises that to achieve this industry...
