Fish egg hatching system Plug and Play

Introduction to the fish egg hatching system

In the fish egg hatching system, the fertilized eggs, obtained from the selected broodstock fish, will be placed and hatched. Each floating egg tray, one in each tank, should be stocked with 100 grams of fertilized eggs. This will result in a total stocking density of 400 gram of eggs per cycle. The fertilized eggs are then evenly spread over the sieves of the floating egg trays and hatch in around 24 hours (depending on the fish species and water temperature, in this example African catfish and water temperature is around 29 degrees Celsius). The larvae will fall through the mesh of the egg trays while the non-hatched eggs will stay behind.

Specifications of the system

• 4x polypropylene fish tanks with 1 outlet in the bottom. Complete with two types of outflow sieves (large and small)
• Sedimentation filter tank (mechanical filtration) allows for removing all the solid particles from the system water flow.
• Pump tank in which pump, freshwater supply and overflow pipe are installed.
• Frame (out of SS304) with adjustable stands for easy system installation.
• Connection for freshwater supply (1x floating valve (automatic filling), 1x ball valve (manual filling))
• 1x Messner pump (70 W – 240 V) (made in Germany)
• 1x 40-watt VGE UV-C unit with SS304 housing (made in The Netherlands)
• 1x Air pump (50 W – 240 V) including supply line and air diffusers
• 4x floating egg trays

Sticky fish eggs are no issue

The fish egg hatching system can be used for all fresh water species with sticky eggs and non-sticky eggs. It is not necessary to treat the eggs to eliminate egg stickiness (e.g. common carp and African catfish). Thus; treating the eggs with chemicals is NOT needed, refraining to do so will result in healthier fry.
