smolt

Untreated smolts adjusted normally to salt water and fattened up.

Some factors which influence the survival of hatchery Atlantic salmon (Salmo salar) smolts utilized for enhancement purposes.

When young salmon and sea trout reach the smolt stage ( at which they prepare to migrate to sea ( they are captured in a trap in the burn and are transferred by road downstream of the reservoir and released.

But surely a scheme must be found whereby those precious smolts can be moved from the top of the river system to the tidal reaches, without their having to run the gauntlet of huge flocks of hungry, voracious birds.

The commission concluded that smallmouth wouldn't affect native steelhead and Chinook populations, since salmon and steelhead smolts use the river as a migration corridor during the high spring flows - a time when smallmouth are less active.

Like smolts, these are pelagic fish - they don't swim deep.

Al igual como ocurre con la trucha arcoiris, el cultivo de la trucha cafe deberia involucrar varias etapas productivas, dentro de la cuales estan: 1) la produccion de ovas en pisciculturas especializadas en manejo reproductivo (hatchery, 2), la produccion de ejemplares juveniles aptos para ser llevados al mar (smolts) y 3) el proceso de engorda de smolts en balsas jaula en el mar hasta lograr un ejemplar adulto con un peso apropiado a cosecha.

For every 100 smolts heading to sea from Scottish rivers, just five adult salmon return.

Despite the early experiments with Icelandic and Norwegian smolts, it was the policy of the Faroese Home-Rule Government to prohibit the importation of smolts (this policy is still in force) to prevent the exposure of local smolts to diseases; all smolts used for fish farming in the Faroe Islands in the early 1980's were delivered from the public-owned P/f Fiskaaling's three freshwater smolt farms, albeit from brood stock raised from the original smolts imported from Norway in 1978.

Typically, only about 6,000 adult hatchery salmon make it back to the hatchery area each year, although the volume varies due to a number of factors, including the number of smolts released, which differs from year to year.

POPULATION: The River Dee Trust has noted a significant increase in smolts which suggests the ecosystem is recovering after the storm
