MES 2/90

[details]		 C. Bullman (CSIRO) FV Megisti Star Orange Roughy research voyage MES 2/1990 took place off St Helens point, Eastern Tasmania during August 1990.

AIMS:

1. To conduct the second trawl survey of the orange roughy spawning ground on the St Helens Hill to provide detailed catch composition (i.e. species by weight) in order to ground truth the acoustic survey to be conducted by the F.W.Tasmanian Enterprise.
2.To determine the size composition, sex composition and maturity of the spawning stock of orange roughy over the St Helens Hill and offish in the surrounding areas using midwater and demersal trawls; and to determine the presence of other species of fish in the vicinity of the aggregation.
3. To fertilize and incubate orange roughy eggs to determine their rate of development.
