Mucosal Defense Mechanism in Fish: An Overview
Abstract: Mucosal surfaces are important physical barriers whose main function is to protect the systemic environment of the body against microbial invasion. It is the first line of defense to protect the animal and also functioning as an active immune tissue. Four mucosal-associated lymphoid tissues (MALTs), which start the immune responses are skin, gills, gut, and nose, have been reported in fish. Humoral and cellular immunity, their regulation and the factors …

Evaluation of Metal Pollution in Wetlands Using Fish as an Indicator
Abstract: The current study has attempted to document the heavy metal pollution in wetlands using fish as an indicator. Heavy metals are one of the most toxic, persistent and widespread groups of contaminants in aquatic systems. Their effects may often occur and remain unrecognized at the individual level but slowly, over a period of time, show up at a population level. Over a few decades globally there has been growing interest …

Assessment of Suitability of Inland Wetland Fishes in Gujarat, India, for Human Consumption: A Focus on Organochlorine Pesticides
Abstract: The work described in this study evaluated the organochlorine pesticide (OCP) residues in the inland wetland fishes of Gujarat, India, and their suitability for human consumption. Among the various OCPs analyzed, isomers of hexachlorocyclohexane (HCH), γ-HCH and β-HCH were detected in 70%–80% of samples. The p,p’-DDE, metabolites of DDT were detected in higher load. Of the nine species of fishes tested, the maximum load of ∑HCH and ∑DDT was recorded …

Toxicity Evaluation of a Few PAHs on a Local Freshwater Fish—Rasbora daniconius
Abstract: Polycyclic Aromatic Hydrocarbons (PAHs) have become ubiquitous pollutants of water resulting mainly from petroleum products. These are absorbed into the living systems and converted into secondary metabolites which show bioaccumulation in the living systems and have several deleterious effects on them. The present study attempts to evaluate toxicity of two such PAHs— Naphthalene and Anthracene—on the freshwater fish, Rasbora daniconius, using pure PAHs dissolved in dichloromethane. LC50 values were seen …

Mucosal Vaccines in Fish: Novel Advances in Technology and Delivery: A Review
Abstract: Vaccines rely on the acquired immune system and prime an animal to a particular antigen so that on subsequent encounter; it is recognized and quickly destroyed. The vast majority of pathogens enter the body via the mucosal surfaces of the gastrointestinal, respiratory, and urogenital tracts, where they initiate mucosal infections that lead to systemic infections. There is strong evidence that an optimum mucosal immune response can prevent systemic infection and …

Impact of invading fish on native species
Abstract: The term "alien species" refers to organisms that have been intentionally or unintentionally introduced outside of their natural range. These organisms have the ability to establish self-sustaining populations, spread beyond the initial point of introduction, and have a negative impact on the environment and the economy. Through crossbreeding with closely related native species, these fish with diverse genetic make-up cause the formation of a new group of organisms with different …
