 The English Mackerel is seen on the East Coast, occasionally 

 in large numbers, each year, moving in a northerly direction. 

 There are few regular fishermen on the East Coast, how- 

 ever, and little is locally known of the habits of these fishes. 

 They have been known to enter the estuary of the Derwent 

 in large numbers as far as Bridgewater, but, owing to the 

 absence of proper means for capturing them, they rarely 

 find their way to the market. This statement also applies 

 to the Bastard John Dorey (Cytttis AustraUs), which is 

 rarely captured, although during the month of May it has 

 been known to enter the estuaries of the Derwent and 

 Tamar in considerable numbers. I am satisfied that the 

 local fishermen have not the proper appliances for the 

 capture of this valuable fish. I suppose a trawl-net is best 

 adapted for their capture, but these nets are not employed 

 here. 



The other members of the family enumerated above are 

 only caught at odd times around the coast, and do not affect 

 the market sup})ly. I am doubtful, however, whether the 

 Zeus faher, i.e., the true John Dorey, is to be found in 

 Tasmanian waters. It is recorded from Tasmania by Dr. 

 Giinther, but it must be exceedingly rare, for I have never 

 seen a specimen.
