Genetic variation analysis between fish eggs and fish muscles of Pimelodus Maculatus species in Parana River through Co1 Gene. In: UNSPECIFIED 1st ed. Asian Federation of Biotechnology Malaysia Chapter, Universiti Putra Malaysia. ISBN 9789671727119
Abstract
Pimelodus maculatus known as yellow catfish or mandi is a migratory fish and important for commercial fisheries. The construction of hydroelectric dams may disrupt the migratory behaviour of the fish in order to spawn which leading to reduction of population of the fish. Fish eggs have a difficulty on morphology observation since they contain similarity in terms of shape, size and colour in order to study the distribution/population of an organism. In order to identify the species, CO1 genetic marker were used to identify the genetic variation between fish egg species with muscles from different geographical areas, Brazil and Argentina, as well as, to study the population of the fish species. By using MEGA software, all sequences were aligned by using ClustalW to construct a phylogenetic tree. DAMBE software and ABGD tool were used to test substitution saturation and species delimitation. The theory of Yoshimi Sato stated that the P. maculatus undergoes short-distance migrants that contradict with the studies of da Silva which stated otherwise. Genetic distance range obtained shows less than 2% between eggs from Brazil with the muscles from Argentina, where there is probability, the fish undergo migration in order to spawn. However, the ABGD and phylogenetic tree shows a conflict for a few individuals from Brazil where there is probability that a few muscles from Brazil are not P. maculatus species. The findings could reveal the effectiveness of CO1 gene as a good genetic marker in order to identify the species of fish and discover the population of the fish.
