Zooplanktonic communities of South East Tasmania 1971-1973

The occurence and distribution of zooplankton species off the east coast of Tasmania was investigated between 1971 and 1973. Samples were collected at stations distributed along three transects extending seaward. Temperature and salinity data was collected at the same time.

Purpose
Using the occurence and distribution of zooplankton, the researcher was wanting to resolve the contradictory hydrological uncertainity at the time about the position of the sub-tropical convergence, by using the indicator species concept.

Statement
Samples were collected by the Sea Fisheries Division, Taroona, for the "Pelagic Fish Project", by the vessel "Penghana". Stations were situated on the east coast of Tasmania. All were distributed in three transects extending seaward for a distance of 30 miles. Four stations on each transect were operated about 10 miles apart, starting from a coastal station, about half a mile from shore. A total of 10 cruises, in which 89 stations were operated, covering a period of 22 months. A standard plankton net with mouth area of 1.0m2 and mesh size um, was used to collect the samples. Seven minute oblique tows with 100 metres of wire released, for deep water stations and five minute oblique tows with 50 metres of wire released for shallow water stations, were maded. The oblique tows were made by lowering the net with a required length of cable released while the vessel was stationary. A few mintues was allowed to have the net reach the required depth. The vessle was then moved forward with the speed of about one knot as soons as the net reached the required depth and ast the same time a winch was used to pull the net up very slowly. The samples were preserved in approximately 5% formalin immediately after each collection. Sub-sampling was carried out by the Modified Whirling Apparatus, and counting was done by using the modified counting disc and apparatus (as described in the thesis). The temperature was recorded by the vessel's "Negretti" and "Zambra" type continuous thermograph which was calibrated in Fahrenheit scale, the results were later converted into Centigrade. The temperature value for Station 29, Cruise IV, was missing. Salinity values for Cruises I to V were not available. The surface water samples were taken immediately after each plankton collection and stored in narrow-ncked screw-tight polyethylene bottles. An inductive salinometer was used to determine salinity. The apparatus was calibrated before each batch of determinations, using Copenhagen Standard Sea Water. The Inductive Salinometer has an accuracy of approximately 0.003 parts per milli.
