FISH HATCHERY

EQUIPMENT

4-tray, 8-tray, and 16-tray vertical incubators are available to use in various combinations to maximize use of available manpower, floor space, and water supply. The design and construction of these vertical incubators offers several advantages:

Vertical Flow: Fresh water enters the rear of a water tray, at the top of the cabinet, upwells through the egg tray and flows over the front wall inside the water tray into a channel which feeds the next lower water tray unit.

Accessability: Each water tray is designed to slide easily forward on level tracks from the front of the cabinet, enabling eggs to be worked on and returned to the tray without removing it from the vertical incubator cabinet. Hatchery personnel may remove individul egg trays entirely to monitor the progress of eggs and fry without distrurbing the remaining trays in the stack.

Versatility: Marisource cabinets may be used in single 8-tray application or may be stacked atop each other to form 16 tray configurations without consuming additional floor space. In the stacjed application, a second water source may be introduced to the lower units, thus insuring ample oxygen for each incubator. Marisource also manufactures a 4-tray incubation unit for small quantity applications such as educational or laboratory environments for segregated batch incubation of hybrid eggs.

Materials: The cabinet itself is constructed of a one-piece welded aluminum frame for lightweight, convenience in stackability, corrosion resistance, and a long useful life. Interior components are molded of plastic which may be easily cleaned, disinfected after or prior to each use, and are resistant to corrosion. Materials will netiher rust nor attck eggs chemically. All incubation components will float.

The barrel is placed in a remote location beside a small stream. Because the system must depend on gravity feed, plumbing for the water source must be located above the barrel. The standpipe connected to the plumbing aerates and controls the water level.

Once the water enters the barrel it upwells through a screen embedded with pea gravel to further settle the water and supply even flow throughout the barrel.

As the eggs hatch, alevin take shelter in the yolk sack and are ready tp enter the stream. When this process is complete, egg baskets must be removed to enable the fry to swim up through the barrel channel and follow the water source to the stream.

Barrel Components (Top to Bottom):

Egg Baskets: Six 22" (55.88 cm) diameter baskets accomodate the eggs until they hatch. Each holds approximately 10,000 trout eggs or 12,000 salmon eggs.

Substrate: Nontoxic and noncorrosive black plastic material serves to aerate and provides a hiding place for fry.

Pea Gravel: Settles the water source for an even flow throughout the incubator

Diffuse: Connects to outside plumbing and initiates aeration of water source.
