Abstract
An apparatus (20) for incubating fish eggs is disclosed. The incubating apparatus (20) includes an insulated container (22) for holding a plurality of preferably square tubes (24). Apparatus (20) is portable and may be operated in a recirculation mode or by running external water through it continually. In the recirculation mode, water flows about a fluid circuit. An air pump (90) provides air to an air diffuser (104). The bubbles from diffuser (104) lift water in air lift tube (86) to tank (88). The water in tank (88) provides a pressure head to force the water throughout the rest of the circuit. Water from tank (88) is communicated through a filter (122) to a manifold chamber (34). The water is distributed from manifold chamber (34) to the plurality of tubes (24). As the water rises upward through tubes (24), it aerates and cleanses the incubating fish eggs. Since the upper portion (54) of tubes (24) is screened, the water has a common level throughout container (22). The water flows between tubes (24) out an exit pipe (50) and back to air lift tube (86). The present apparatus (20) provides a portable incubating device as a replacement for stationary fish hatcheries.
