24 MARINE AND FEESH WATER PISCICULTURE. 



some SO miles distant from the metropolis. The Winge- 

 carribee River, a permanent stream, which takes its rise in 

 an extensive series of swamps supplied from an enormous 

 catchment area, flows past the hatchery site and maintains 

 a comparatively low temperature right through the summer 

 months. There is abundant reason to expect that the culture 

 of non-indigenous fresh-water fish of various kinds could be 

 carried on there with every probability of success. 



About two years since the writer made the experiment of 

 travelling trout fry to the several streams assigned to them 

 in jars about three parts filled with water and hermetically 

 sealed. This mode of transmission proved so successful 

 that at Sydney it has quite superseded the old method of 

 forwarding in open jars. Pry can be sent in the jars for any 

 reasonable distance. After determining by actual experiment 

 that it would exist so imprisoned for seventy-two hours, the 

 method was still further tested by shij^ping to Wellington, 

 New Zealand, some fry of the ova which originally had been 

 sent thence and hatched out in New South Wales. The 

 attempt proved successful, and in like manner the experiment 

 was repeated between Wellington and Sydney. 



MAEINE AND PRESH WATER PISCICULTURE. 



In respect to marine and fresh water fish culture proper, 

 not much has yet been attempted. Part 3 of the Eisheries 

 Act, 1881, was evidently framed under the idea that if proper 

 inducements were offered to freeholders and leaseholders of 

 land suitable for the purpose, they would enter upon the 

 establishment of artificial marine fisheries, but that part of 

 the Act has so far proved a dead letter. The coast, however, 

 abounds with lakes and lagoons, the property of the Crown, 

 which could easily be made accessible to the influx and eflux 

 of the tides ; if the Bill to regulate the fisheries elsewhere 

 noticed in this pamphlet becomes law, these and other suit- 

 able waters will be available to the public for lease for 

 general fisheries purposes. It will probably be necessary for 

 the Government to take the matter up in the first instance, 

 in order to show what can be done in the shape of marine 

 fish culture, and there are many places at which experiments 

 in this direction can be carried out at quite inconsiderable 

 cost — one exceptionally suitable place, at Lake Macquarie, 

 may be mentioned. On the southern shore of the channel
