Development of a risk assessment method for sea trout in coastal areas exploited for aquaculture

Aquaculture Environment Interactions, 2021
The regulation of aquaculture production in Norway considers the potential impact of salmon lice on wild fish. However, most attention has been focused on impacts on wild Atlantic salmon, despite the fact that anadromous brown trout spend the majority of

Sea lice as a density-dependent constraint to salmonid farming [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2012
Fisheries catches worldwide have shown no increase over the last two decades, while aquaculture has been booming. To cover the demand for fish in the growing human population, continued high growth rates in aquaculture are needed. A potential constraint to such growth is infectious diseases, as disease transmission rates are expected to increase with ...

Monitoring parasitic abundance in cage-based aquaculture : the effects of clustering [PDF]

, 2006
Most discussions of sampling protocols within the literature on monitoring aquatic parasites are based on the assumptions of simple random sampling. There has been a growing recognition within the fields of human and terrestrial veterinary epidemiology ...

Host factors important in sea lice infections [PDF]

ICES Journal of Marine Science, 1998
An overview is presented on the interactive parameters that influence fish susceptibility to infection. In particular, the importance of genetically determined resistance, stress, immunocompetency, and nutrition are discussed in relation to their influence on susceptibility of salmonids to infection with sea lice.

Navigating Inter‐Municipal Collaboration Challenges: 'In‐Tensions' in Shared Service Center and Joint Venture Arrangements

Financial Accountability &Management, EarlyView.
ABSTRACT Municipal collaborations such as shared service centers and joint ventures are widely promoted as ways to strengthen local service capacity. Yet they often develop in uneven and sometimes unstable ways. This paper examines why arrangements built on similar institutional promises take such different trajectories in practice.

Understanding sources of sea lice for salmon farms in Chile [PDF]

Preventive Veterinary Medicine, 2013
The decline of fisheries over recent decades and a growing human population has coincided with an increase in aquaculture production. As farmed fish densities increase, so have their rates of infectious diseases, as predicted by the theory of density-dependent disease transmission.

Commercial clays in cosmetic formulations for hair care: Characterization and application to improve the mechanical properties of hair fibre

International Journal of Cosmetic Science, EarlyView.
The shampoo and conditioner bar formulations enhanced hair gloss, promoting softness, improved cuticle alignment, and effective protection of hair shafts against external aggressors. Findings from mechanical properties measurements indicate that the clay‐containing formulations enhance the mechanical strength of hair, contributing to stronger and more ...
