Abstract

The samples of flatfishes were collected along the Mon State from July to December 2017 including Mawlamyine, Kyaikkhami, Setse, Zee-Phyu-Thaung Belugyun island, Paung and Thaton. The total 21 species of flatfishes were recorded in Mon State. Moreover, the relative abundance, diversity and similarity were conducted using Simpson Index, Shannon index and Jacquard’s index etc. According to the present study, the Cynoglossidae was the most dominant family and the most dominant species was Cynoglossusarelfor the present study. The relative abundance of Mawlamyine and November was relatively the highest. Furthermore, Mawlamyine was the highest diversity and Thaton was the lowest diversity. The JI value between Mawlamyine and Paung is the highest while it is the lowest between Setse and Thaton. Likewise, the JI value between August and September and the value between September and November are the same as well as the highest while it is the lowest for the comparison between July and August. The present study also expects to become a basic informational providing data for further observing (in Academic) on Order Pleuronectiformes (flatfishes) along the Mon State.

Highlights

Pleuronectiformes were first named in 1758 by Linnaeus; pleuro meaning "on side" and necto meaning "swim"
A total of 5 families, including 21 species of flatfishes were recorded in Mon State
Cynoglossidae was found in every station abundantly but Soleidae was found in Mawlamyine, Paung and Thaton

Summary

Introduction

Pleuronectiformes were first named in 1758 by Linnaeus; pleuro meaning "on side" and necto meaning "swim". Flatfishes are easy to recognize since this is the only group of fishes that is not bilaterally symmetrical. The ventral side of the body is eyeless and white, while the dorsal is dark and has both eyes. They swim by the undulation of the body, and usually remain close to the bottom on the continental shelf. Flatfishes are one of the important components in several demersal communities around the world. Flatfishes are important predators in many demersal communities. They may serve as an important link between demersal production and human consumption[9]
