FROM LITTLE THINGS BIG THINGS GROW: Bayley Goode pictured with daughter Sakura, and the incredible bonsai that Bayley has offered as a prize to all who donate to Buy a Bale on his Goode Organics website. With all donations over $5 going into the draw to win the prize, this living artform has been independently valued at $2500. Bonsai served as the initial inspiration for Bayley’s business Goode Organics where fertiliser was a crucial element of maintaining these amazing trees. His daughter Sakura has also proven to be a driving force, as Bayley strives to create a connection with the land for his daughter in this age of technology. Regularly joining him on deliveries, and engaging with farmers and livestock in his day to day work, Bayley and Sakura have also started a huge vegie patch at home. Turn to page 4 to read the story.
ALONG the mountain fed Jamieson River, and in spots along the Queens Creek (part of the water shed from the King River, just near Cheshunt) a group of dedicated trout enthusiasts are quietly going about the rejuvenation of wild trout stocks in the state’s waterways. Matt Byrne, president of the Mansfield and District Fly Fishing Club, was inspired after a trip to America and witnessing the revolutionary effects the Jordan/Scotty Fish Egg Incubator was having on wild trout breeding programs in the country. Up until the invention of the Jordan/Scotty Incubator, disease was the primary cause of mortality in hatchery-harvested eggs. “In-stream incubators are not a new thing,” Graham Godber, secretary of the Mansfield and District Fly Fishing Club, said. “The problem though is that once you get a disease like White Spot for instance in the ova it spreads. “Any egg that is in contact with it gets it straight away, and before you know it the whole incubator and all the eggs are infected.
“The transmission rate is so high, that in no time the disease can go right through a whole hatchery. “For decades it’s been a problem in raising trout and other fish as well in hatcheries.” To combat this problem, commercial hatcheries are constantly monitoring for disease and batches of eggs are segregated in numerous containers in order to isolate outbreaks. The revolutionary design of the Jordan/Scotty Incubator takes this segregation one step further, by separating each and every egg in a plastic honeycomb configuration. Within the incubator there are five cells with 200 eggs to each cell. The individual cells are then fixed together accounting for 1000 eggs and then the incubator is placed in-stream. “The beauty of the device is that any disease is only confined to the infected egg and it is not transmissible due to its isolation,” Mr Godber said. “Though a game changer it is quite labour intensive to load up the incubator, and at this stage commercial hatcheries couldn’t really do it as a viable alternative. ■ Continued page 2
