TLDR
The results of this study showed that high stocking density produced a chronic stress situation and there was both haemoconcentration and a decrease in alternative complement pathway, an important component of the immune system of fish.Abstract:
High stocking density has been shown to produce a wide variety of effects on cultured fish populations, such as alterations in behavior and poor feed utilization, resulting in mortality and poor growth. High stocking density has also been reported to produce chronic stress and mobilization of energy sources in fish. There are few studies focusing on the effect of high stocking density on one of the most important marine fish species for Mediterranean aquaculture, gilthead seabream (Sparus aurata). Consequently, this study investigates the effect of high stocking density on juveniles of this species, focusing on effects of stocking density on growth, biochemical composition, immune status and hematology.read more

Innate immunity of fish (overview).
TL;DR: The innate immune system is the only defence weapon of invertebrates and a fundamental defence mechanism of fish and plays an instructive role in the acquired immune response and homeostasis and is therefore equally important in higher vertebrates.

Fish welfare: Current issues in aquaculture
TL;DR: The scientific data that allows us to interpret the effects of disease, handling, transport, food deprivation, and slaughter technique on fish welfare are reviewed and caution should be taken when interpreting "abnormal" fish behaviour.

TL;DR: This paper focuses on welfare as the absence of suffering in fish, arguing that complex animals with sophisticated behaviour, such as fish, probably have the capacity for suffer ing, though this may be different in degree and kind from the human experience of this state.

TL;DR: Large differences have been found across species, breeds and individuals, which reflect the contribution of genetic factors and environmental influences, especially during development, in HPA axis functioning.

A simple method for the isolation and purification of total lipides from animal tissues.
TL;DR: In this paper, the authors described a simplified version of the method and reported the results of a study of its application to different tissues, including the efficiency of the washing procedure in terms of the removal from tissue lipides of some non-lipide substances of special biochemical interest.

Physiological changes in fish from stress in aquaculture with emphasis on the response and effects of corticosteroids
Bruce A. Barton,George K. Iwama +1 more
TL;DR: Stress, through the action of corticosteroids, may reduce immunocompetence by influencing lymphocyte numbers and antibody-production capacity, and affect reproduction by altering levels and patterns of reproductive hormones that influence maturation.

TL;DR: It is shown, by means of intraperitoneal implantation of cortisol, that chronic elevation of plasma cortisol levels in the brown trout results in a dose-dependent increase in mortality due to common bacterial and fungal diseases.
