Effects of Turbidity and Suspended Solids on Salmonids [PDF]
, 2001 white paperHuman activities in Northwestern watersheds, including logging, grazing, agriculture, mining, road building, urbanization, and commercial construction contribute to periodic pulses or chronic levels of suspended sediment in streams ...

PCR-RFLP Method to Identify Salmonid Species of Economic Importance
Scientific Papers Animal Science and Biotechnologies, 2023 The identification of different fish species by molecular methods has become necessary to avoid both the incorrect labelling of individuals involved in repopulation programmes and the commercial frauds on the fish market.

Journal of Fish Biology, EarlyView.Abstract Wild Atlantic salmon migrate to sea following completion of a developmental process known as parr‐smolt transformation (PST), which establishes a seawater (SW) tolerant phenotype. Effective imitation of this aspect of anadromous life history is a crucial aspect of commercial salmon production, with current industry practice being marred by ...

Journal of Fish Biology, EarlyView.Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Is There Abundant Zooplankton Prey for Salmonids in the Subarctic North Pacific in Winter?
, 1999 Macrozooplankton was sampled using a North Pacific standard plankton net during two trans-Pacific cruises of the R/V Kaiyo maru at 27 and 23 stations in a wide area of the northern North Pacific Ocean in November-December 1992 and January 1996 ...

Bridging the protein gap with single-cell protein use in aquafeeds
Frontiers in Marine ScienceBlue foods from aquaculture are essential in bridging the protein gap to feed the human population in the future. However, for aquaculture production to be sustainable, production must be within planetary boundaries, and sourcing of sustainable raw ...

Knowledge and Management of Aquatic Ecosystems, 2017 Quantifying patterns of prey resource use is fundamental to identify mechanisms enabling the coexistence of related fish species. Trophic interactions between the native brown trout, Salmo trutta, and the introduced brook trout, Salvelinus fontinalis ...

Journal of Fish Biology, EarlyView.Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Ecology and Evolution, 2019 The anadromous salmon life cycle includes two migratory events, downstream smolt migration and adult homing migration, during which they must navigate with high precision.
