The presence of the body colour polymorphism in the tropical invasive pest giant African snail is reported for the first time from South India. Three different body colour polymorphs were recognised viz. grey, black and white. The grey body colour is the most common polymorph. The black and white colour polymorphs are found to be in almost equal proportions in the reported localities with the grey counterparts. The cytochrome oxidase subunit I (COI) sequences of the three colour polymorphs are found to be identical. The presence of the body colour polymorphism in south India may be attributed to the avian predation and other selection pressures.

Giant clam population has been decreased in a few years. Resource management requires information from various aspects, such as ecological, population, and other aspects. This study was aimed at assessing the genetic profile of Tridacna giant clam in Wakatobi National Park waters using Cytochrome oxidase subunit I (COI) genetic marker. Sample collection was conducted around the three main islands, i.e., Wangi-wangi, Kaledupa, and Tomia. Genetic analysis using COI gene may contribute in identifying giant clams up to the species level and showed the relationship among species. The research found 41 specific nucleotide sites for the clams. T. crocea, T. squamosa and T. maxima had 2, 15 and 24 sites, respectively. COI gene as a biological marker was able to separate groups of giant clam by species. Nucleotide variation of T. crocea from Wakatobi was the highest among other locations, so it could be used as a genetic source for translocation and domestication. Keywords: cytochrome oxidase subunit I, specific nucleotide, Tridacna, Wakatobi National Park

Crassostrea Oyster

Oysters belong to the Crassostrea, which is a type of shellfish that lives as benthos in waters under the same substrate and environmental conditions will exhibit similar morphological changes in response. There are many types of oysters that have a similar shape are often an obstacle to differentiate of Crassostrea species through morphological identification. The purpose of this research was to identify the types of oysters found in the waters of Delta Cimanuk through analysis of the morphology and nucleotide diversity of Cytochrome Oxidase subunit I (COI) gene, as basic information on proper management and conservation. The morphological identification results show that there were two species of the Crassostrea. Identification of species through the Barcoding DNA technique shows that there is one type of oyster: Crassostrea iredalei with an accuracy of 99.5%.

DNA barcoding has been proposed as a means of quick species identification using a short standardized segment of DNA. Two species (Eleotris fusca and Glossogobius giuris) from the family Gobiidae and Eleotridae were selected for DNA barcoding using samples collected from different regions of Bangladesh. Cytochrome Oxidase Subunit I (COI) gene was sequenced from two different gobi fishes and compared with two previously published similar sequences from the genera Eleotris and Glossogobius. Multiple sequence alignment and the molecular systematic study were performed. The DNA barcode technique identified the two species. The study provides a good example of how DNA barcoding can build upon its primary mission of species identification and use available data to integrate genetic variation investigated at the local scale into a global framework.Bangladesh J.
