Percentage classification, according to contents, of stomachs of the gempylid fish Thyrsifes ofun taken along the south coast of Victoriain different months. Numbers of stomachs are above the columns. Anchovy means E. australis. For further explanation see text (from Blackburn 1957).common there in summer. The best evidence for thisstatement is the seasonally changing representationof E. azbstralis in the diet of the gempylid fishThyrsites atun, which was studied by Blackburn (1957and references there). This species occurs and is fishedalong the coasts close to land, but is not common atfishable sizes in bays. Figure 12 shows, for a section ofthe Victorian coast on to which Port Phillip and otherinlet waters open, that T. atm feeds on E. australisfrom May through December, but not from Januarythrough April. Reports of anchovy schools at sea, byfishermen, indicate a similar pattern of seasonalchange.3. Schools of E. australis, of the sizes mentioned inthe preceding paragraph, have been seen approachingand going through the entrances of Gippsland Lakes,Port Phillip, and Westernport (Victoria), from thesea, in the spring months. Records of similar schoolsgoing out to sea are lacking, however.4. Anchovies of the sizes just mentioned are muchmore abundant in bays than in the sea in the summer,which is the spawning period. Some fish of these sizesremain in the bays in winter.These observations reveal a tendency, increasingwith age, for some E. australis of the southern subspeciesto move each year from the inlets to the sea(probably in autumn) and back again (in spring).The inlets become colder than the sea in autumn andwarmer than the sea in spring (e.g., Garner 1954,Port Phillip). The older anchovies may therefore bedisplaying positive thermotaxis.REFERENCESBlackburn, M. 1941. The economic biology of some Australianclupeoid fish. Aust. G.S.I.R. Bull., (138) :1-135.-1950a.
