HATCHING JAR X 8 LITRES

A fish hatching jar (also called an egg hatching jar or Zug jar) is a specialized container used to incubate fertilized fish eggs. Water flows continuously upward through the jar, keeping the eggs gently suspended, well-oxygenated, and free of debris.

Common uses

• Hatching tilapia eggs
• Trout and salmon eggs
• Carp eggs
• Catfish eggs (in some hatchery systems)
• Many other freshwater fish species

Features

• Transparent plastic or glass body for easy observation
• Conical (funnel-shaped) design
• Water inlet at the bottom
• Overflow outlet at the top
• Gentle upward water flow to circulate the eggs without damaging them

Typical sizes

• 1–2 liters: Small-scale or hobby hatcheries
• 5–10 liters: Small commercial hatcheries
• 20 liters or larger: Commercial fish farms

Benefits

• High oxygen levels for developing eggs
• Reduces fungal growth by keeping eggs separated
• Removes dead eggs and waste through water circulation
• Improves hatch rates when properly managed
