Study Regarding the Conformation in Four Populations of Reproduction - Female - Rainbow Trout (Oncorhynchus Mykiss) From Trout Farm Fiad, County of Bistrita-Nasaud

Scientific Papers Animal Science and Biotechnologies, 2023
Rainbow trout (Oncorhynchus mykiss) is the main specie exploited in the salmon complexes. The reason is the plasticity and resistance to changes in environmental and disease factors, and due to fast growth rate obtained by the processes of selection and ...

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

Archaeometry, EarlyView.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Comparative study of blood biochemistry in clinically healthy farmed barramundi (Lates calcarifer) and rainbow trout (Oncorhynchus mykiss) from freshwater recirculating aquaculture systems

Australian Veterinary Journal, EarlyView.
Barramundi (Lates calcarifer) is an economically significant aquaculture species and ranks among Australia's top five farmed finfish. As global production intensifies, understanding the physiology and health of barramundi is essential to support animal welfare and industry profitability.

Using structured decision making to evaluate the tradeoffs of selective fish passage

Conservation Science and Practice, EarlyView.
Abstract Dams have dramatically altered rivers and are a major contributor to native fish population declines. However, many dams serve important ecological, social, and economic functions, such as flood control, invasive species control, and provision of recreational opportunities.

Thermal tolerance and vulnerability to warming differ between populations of wild Oncorhynchus mykiss near the species’ southern range limit

Scientific Reports, 2023
Fish habitat temperatures are increasing due to human impacts including climate change. For broadly distributed species, thermal tolerance can vary at the population level, making it challenging to predict which populations are most vulnerable to warming.

A Review of a Decade of Anadromous Salmonid Hatchery (And Stocking) Research: Insights for Policy, Management and a Changing Climate

Fish and Fisheries, EarlyView.
ABSTRACT Hatcheries and stocking programmes have long been a cornerstone of fisheries management, seen as tools for fisheries enhancement and/or conservation of threatened populations. Their use draws controversy, however, from a growing body of research over the last 50 years suggesting that stocking can have negative consequences for wild stocks, and

Predator-driven nutrient recycling in California stream ecosystems. [PDF]

PLoS ONE, 2013
Nutrient recycling by consumers in streams can influence ecosystem nutrient availability and the assemblage and growth of photoautotrophs. Stream fishes can play a large role in nutrient recycling, but contributions by other vertebrates to overall ...

Ichthyobodosis in Oncorynchus mykiss Fry

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1998
On Februray 1998 in one of the trout farm of Kohkiloieh & Boyer Ahmad province was observed the mass mortality of trout fry with 3 centimeters total length. The rate of mortality was 40%. The sampling was done randomly from various traphs of hatchery hall and 200 fish fry sampled.
