Fish Egg Hatching Jar
Product Code: J30
The J30 Fish Egg Hatching Jar is a McDonald-type egg incubator that has become the industry standard for hatching salmonid and warm-water fish eggs in commercial hatcheries, aquaculture facilities and fisheries enhancement programmes. Manufactured from clear, high-impact plastic, the one-piece moulded design provides a smooth interior with no seams, lips or gaps where eggs can become trapped or bacteria can accumulate. Water is introduced through the centre tube at approximately 1 US gallon per minute (3.8 L/min), gently suspending and rotating the eggs to provide uniform oxygenation and maximise hatch rates.
The J30 includes a 1,000-micron removable top screen that prevents egg loss during incubation. Once the fry hatch, the screen is removed, allowing the fish to swim out naturally into the receiving tank. With a 6-litre capacity, the jar can incubate approximately 100,000 trout eggs (capacity varies depending on egg size and species). The J30 is widely used for trout, salmon, steelhead, hybrid striped bass, catfish, tilapia and many other freshwater fish species. An Optional Jar Hanger is available for mounting the jar without the need for a separate stand.
The all plastic hatching jar hanger allows jars to be used without a bench or separate stand. Accepts up to 1.5″ hanging lip.
