Application of gel electrophoresis in fisheries?

Gel electrophoresis is used in fisheries primarily for genetic analysis and species identification. It allows researchers to separate DNA, RNA, or proteins based on their size and charge, enabling the identification of genetic markers that can distinguish between species or populations. This technique helps in assessing biodiversity, monitoring fish stocks, and studying breeding patterns, which are crucial for conservation and management efforts in aquatic ecosystems. Additionally, it can aid in the detection of illegal fishing practices by verifying the species of caught fish.
