FRY / JUVENILE REARING PONDS Sample Clauses

FRY / JUVENILE REARING PONDS. ‌ A total of thirty-six 10’ x 200’ raceways are planned to be used for rearing of salmon fry and juveniles. The 10’ x 200’ x 8’d (approximate structural dimensions) raceways would be composed of individual sections created by inserting pond screens in wall channels. Sections are proposed to be fish grow-out units of 10 feet wide by 12 feet at both ends of each pond with 25 foot sections in between (average water depth of approximately 5.6 feet). The short 12 foot section on West side of each pond is proposed to be used for initial ponding of fry with grow out occurring from West to East in a direction that is counter to pond flow. This will prevent the need to clean areas of the pond that are unused and will allow for additional aeration of water supply (e.g. waterfall over stop logs at center of ponds). Additional program flexibility may be provided by inclusion of a 12 to 25 foot long divider wall or screen down the center of each pond on the West end. This would allow the grow out of two separate batches of fry in the same pond, thus, providing the ability to catch one batch up to the other prior to ponding them together. Juvenile collection areas (10’w x 12’l kettles) at the downstream end of ponds are included in pond design (see Section A in Appendix No. 7 – Salmon Hatchery Remodel Components) and are expected to help with fish handling and pond cleaning. Besides at pond outlets, stop log guides will also be provided at least at the mid-point of ponds to allow two different pond levels when desired (e.g. mass marking, aeration of water supply).
