Shhhh It's A Secret! Things that the industry don't want you to know!

• According to Austasia Aquaculture the formula to stimulate Yabbies breeding is... 1 male to 4 females, raise the water temperature from 17C to >23C
• Companion Worm Farms. Live worms are great natural food for freshwater fish. They are able to convert garden and household green waste into food for fish and by products for the garden. You can also combine dried worms with breadcrumbs to produce a 'dust & crumble' for fry/fingerlings.
• Grind Yabbies and parts of Yabbies with other produce and freeze or refrigerate to make a great storable feed for a range of aquaculture/aquarium species.
• Eucalyptus oil could be used as an antiseptic for fish. Apply to the damaged area and return the fish to the water. (Use in conjunction with other remedies eg. salt bath)

• Reproduce the specific fish species natural habitat in aquaculture. eg. Murray Cod spend 99% of the life in a hide (log etc.). Place artificial hides in tanks.
