Researchers at the Center for Food Research and Development (CIAD) are working on a project to farm pathogen-free copepods that will later be used as food in the hatchery.
The main objective of this initiative is to eliminate the risk of introducing predators or unwanted organisms.
According to Carmela Ana Puello Cruz, a researcher at the Regional Unit in Mazatlan, Sinaloa, the inclusion of this type of pathogen-free food in small doses and only in larvae of various species will increase their survival and growth, reports El Reportero de la Comunidad.
CIAD scientists took into account the characteristics and feeding behavior of larvae of bullseye puffer fish, spotted rose snapper and white shrimp.
Copepods, which are the natural food of marine larvae of crustaceans and fish have high levels of essential fatty acids and natural antioxidants that provide energy and are easy to digest for the early larval stages.
But when they are collected from the wild, they have unwanted organisms that may pose a risk for larval culture. Herein lies the importance of this initiative to cultivate copepods without pathogens.
