Hatchery room, incubation area, feed storage, 

 material storage, crew's room, toilet facilities, 

 and small office area. Administrative offices 

 and visitor facilities are not recommended

Allow 2.,')-foot aisles between tanks and 4-fi 

 feet around ends. Floor: concrete with 

 broom finish, slope (l" in 10') for drainage. 

 Walls and ceilings should be cement asbes- 

 tos or other waterproof material. Water sup- 

 ply and drain systems should be designed 

 for flexibility and alteration. Buried lines 

 should be kept to a minimum. A fish tran- 

 sport system (pipe) from tank room to out- 

 side ponds is desirable. Portals in the walls 

 are convenient for moving fish out of the 

 hatchery building.

 room should be provided for egg incubation. 

 Use of stacked commercial incubators is 

 recommended. Permit flexibility in arrang- 

 ing incubators, small troughs, or tanks 

 within the room. 



A separate storage area for dry feed is recom- 

 mended because of undesirable odors. It 

 should be located convenient to use area. 

 Consider bulk feed storage and handling 

 where more than 50 tons of feed is required 

 annually. Provide storage for one-fourth of 

 annual dry feed requirements with protec- 

 tion against moisture and vermin. There 

 should be proper ventilation and tempera- 

 ture control. The delivery area should have 

 turnaround room for large trucks. Include 

 elevation loading dock or mechanical 

 unloading equipment. If moist pellets are 

 used, cold storage (lO°F) for fiO-days supply 

 should be provided. 



Locate convenient to tank room, provide 

 ample size for intended purpose, and design 

 for maximum utilization of wall space with 

 shelves and storage lockers. 



Main offices should be located in a separate 

 administration building. 



Equipped and sized in accordance with antici- 

 pated needs.
