MEXICO - In order to boost production of spotted rose snapper (Lutjanus guttatus) and streamline the process of cultivation, researchers from the National Fisheries Institute (INAPESCA) have conducted studies on the effect of temperature on larval development of this species on fish farms.

The Directorate General of Aquaculture Research INAPESCA reported that for the experimental work of this project, conducted in collaboration with the Interdisciplinary Center of Marine Sciences (CICIMAR) and the Technological Institute of Boca del Rio, 200 fertilized eggs were planted.

The organisms were grown in different levels of heat, which ranged from 22 to 30°C, which allowed the researchers to evaluate the effect of temperature on growth and consumption of yolk reserves (nutrients).

The body of the Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA) explained that the height of the muscle, the total length of the larvae and incubation time were studied as morphometric analysis avriables.

Early results from these experiments indicate that, at the beginning of the reproductive period, the total length of the larvae was higher in culture at 24° C.
