Species Compositiom and Distribution of Seaweeds at Thi Nai Lagoon, Binh Dinh Province

Abstract

This paper presents results on species composition and distribution of seaweeds at Nai lagoon, Ninh Thua province from 2013 until 2014 at 12 sites was showed that, at Nai lagoon area we was recording
 43 species of marine seaweeds, they are belonging to four divisions, as: Cyanophytes, Rhodophytes, Phaeophytes and Chlorophytes. Among them, eight species are classified in Cyanophytes (comprising 18.6% of total species); eleven species in Rhodophytes (25.6%); four species in Phaeophytes (9.3%) and twenty two species in Chlorophytes (46,5%). The species composition of marine seaweeds from Thi Nai lagoon show significant differences in the species composition as follows: 8 species (side number 4, 13 and 18) to 21 (side number 10) and average value is 12.2 species per side. The number species at dry season is 40 and rainy season is 30 (there are 30 species in of boots dry and rainy seasons) Coefficient homogeneous is oscillating from 0.10 (side number 4 and 5) to 0.66 (5 and 7). The current investigations show that 39 species of 43 species were collected in the littoral zone and 35 species in sub-littoral zone (31 species are distributing in both the tide and the sub tide). Marine algal flora in Thi Nai lagoon is represented by tropical elements as defined by Cheney.

Examining morphological measurement relationships to differentiate between sexes in slender mudskipper Periophthalmus gracilis (Eggert, 1935)

“…Periophthalmus gracilis is a member of the Oxudercidae family, comprising 32 genera and 58 species [1]. These fish are found in the Indo-Pacific and Western Pacific regions [2], including the coastal mudflats of Singapore, Indonesia, Malaysia, Thailand, and Vietnam in Southeast Asia [3][4][5][6][7][8]. This species is highly valued for food and has significant economic importance in Taiwan and Japan [9], as well as being sought after as an ornamental fish.…”

Phylogenics of the genus Glossogobius in the Mekong Delta based on the mitochondrial cytochrome b (cytb) gene

“…The area's coastline is more than 700 km, with about 360,000 km 2 within the exclusive economic zone bordering the East Sea and the Gulf of Thailand, creating favorable conditions for agriculture and fisheries development [ 1 ]. These natural conditions have developed the fish system of this area, in which the goby species of the family Gobiidae are pretty diverse [ [2] , [3] , [4] , [5] ].…”

“…This order is one of the most significant species compositions in the bony fish class, in which the number of families and genera of this order has not yet been unified [ 7 ]. Among the exploited gobiids, the species of the Gobiidae family play an important role because some species have a higher economic value than others, contributing to the ecosystem's biodiversity due to a large number of fish species [ 3 , 7 , 8 ].…”
