Emergence of Atlantic salmon fry from gravels of varying composition : a laboratory study

Author: R H Peterson; J L Metcalfe
Publisher: St. Andrews, N.B. : Fisheries and Environmental Sciences, Dept. of Fisheries and Oceans, Biological Station, 1981.
Series: Technical report / Biological Station, St. Andrews, N.B., 137th; Canadian technical report of fisheries and aquatic sciences, 1020.
Edition/Format:   Print book : National government publication : English
Summary:
Atlantic salmon eggs were incubated in various gravel and sand mixtures with various water flows and two directions of water current. Fine sand (0.06-0.5 mm) was more effective than c oarse sand (0.5-2.2 mm) in reducing numbers of emergent fry. The number of fry emerging was related to the formula Sf/8 + Sc/16 where Sf = proportion of fine sand and Sc proportion of coarse sand in the gravel mixture. Emergence was  Read more...

Abstract:

Atlantic salmon eggs were incubated in various gravel and sand mixtures with various water flows and two directions of water current. Fine sand (0.06-0.5 mm) was more effective than c oarse sand (0.5-2.2 mm) in reducing numbers of emergent fry. The number of fry emerging was related to the formula Sf/8 + Sc/16 where Sf = proportion of fine sand and Sc proportion of coarse sand in the gravel mixture. Emergence was not affected by reduction of water supply to the eggs. Strong upwelling water currents mitigated the effects of sand to some degree. Upwelling water currents also induced earier fry emergence. There was a tendency for smaller fry to emerge later.
