Project details
| Title: | Biomass estimation of Eastern Zone and Cascade Plateau orange roughy based on winter 2004 industry acoustic surveys |
| Id: | 2194 |
| Acronym: | Biomass Estimation of Orange Roughy |
| Investigator(s): | Tim Ryan
CSIRO Oceans & Atmosphere - Hobart [details] |
| Description: | Industry has successfully organised and conducted acoustic surveys in the winter of 2004 on the Cascade and Eastern zone spawning orange roughy. The surveys mark an uptake by industry of methods developed by CSIRO over the last 14 years. The acoustic and biological data from these surveys will need to be analysed and a written report of the biomass at each ground determined. This snapshot biomass will be then used in the VPA model of both fisheries to determine the status of the stock at both grounds. While in future years this analysis could conceivably be left to industry to organise, CSIRO is currently the only entity with sufficient expertise to take on this type of analysis. WITHOUT THIS ANALYSIS NO UPDATE OF THE STATUS OF THE STOCK ON THE TWO GROUNDS WILL BE POSSIBLE. |
