Health & Welfare
As wide use of antibiotics has led to antibiotic resistance in fish pathogens, vaccines present an alternative control method to prevent bacterial diseases.

In a study, the authors evaluated the immune responses and host protection of hybrid catfish and channel catfish against the ich parasite (Ichthyophthirius multifiliis).
Health & Welfare
The authors used Ichthyophthirius multifiliis (ich) and fluorescent-tagged Edwardsiella ictaluri to examine whether parasites vector bacteria into fish.
Health & Welfare
The authors conducted a study to evaluate whether tilapia infected with Gyrodactylus were more susceptible to Streptococcus iniae. The research found that fish with a solo infection of Gyrodactylus or Streptococcus had less than 7 percent total mortality.
Health & Welfare
In research on alternatives to formalin treatment to control Ich infestation, the authors performed a study that compared the immune responses of Nile tilapia and red tilapia against the parasite.

Dietary lipids are important sources of energy and the essential fatty acids needed by fish for growth and development.
Health & Welfare
Vaccination against the Ich parasite is an alternative to chemical treatment. Fish develop a humoral immune response to trophont antigens, with the degree of protection related to the immunizing doses of trophonts used.
Health & Welfare
Tilapia vaccines can protect the fish against infectious diseases by providing pathogen-specific acquired immunity that prevents recurring infections.

Dietary gossypol from cotton seeds, if present in large amounts in a diet, causes unfavorable physiological effects in monogastric animals including fish.
