The morphology and phylogeny of the diatom genera Rhizosolenia, Proboscia, Pseudosolenia and Neocalyptrella from Gulf of Thailand and the Andaman Sea, with description of Rhizosolenia loanicola sp. nov., Proboscia siamensis sp. nov. and Probosciales ord. nov.

Idiosepius biserialis and Idiosepius thailandicus have been previously described as separate species although the difference in morphological characters is only the arrangement of pegs in tentacular-club suckers. The former species inhabits sea grass beds in the Andaman Sea of Thailand. The latter species inhabits mangroves in the eastern Gulf of Thailand. The present study of reproductive behaviour, mating, and spawning of the two species in captivity demonstrated that they are closely related. Copulation was performed using tentacles by the male for fixation of spermatophores at the buccal region of the female. Behavioural patterns were distinguished based on the hovering and adhering positions of each sex. Cross-mating between two species was initiated and observed, yielding fertilized eggs which developed to the organogenesis stage. Reproductive behaviour of crossed pairs was similar to those of individual species. This study revealed that the two ‘species’ are not reproductively isolated.

A New Species

Four species of Thinolestris Grootaert & Meuffels are known so far, including T. nigra sp. nov., which is described here from Singapore, Malaysia and Brunei. New morphological data on the genus are given. At the moment, Thinolestris is only known from Andaman Sea, Strait of Singapore, South China Sea, Celebes Sea, Bismarck Sea and the Coral Sea. It is not yet known from North Australia nor from the Gulf of Thailand, or farther north. Thinolestris adults are active on beaches with small pebbles mixed with sandy patches. It is not found on rocks, pure sandy beaches nor mangroves.

Abstract We examined the diversity and host use of sponge-associated barnacles of Thailand (Andaman Sea and the Gulf of Thailand) using a combined morphological and molecular approach. Eight barnacle species (including two new species) were collected from 12 host sponges. Host-specific barnacle species includes Acasta lappasp. nov., which exclusively inhabits the sponge Mycale sp. Acasta milkaesp. nov. was only collected from the sponge Callyspongia cf. diffusa (Ridley, 1884). Multatria filigranus (Broch, 1916) were found in the encrusting soft sponges Monanchora unguiculata (Dendy, 1922) and Clathria sp. Pyrgospongia stellula (Rosell, 1975) inhabits the sponges Spheciospongia vagabunda (Ridley, 1884). Generalist barnacle species includes Euacsta ctenodentia (Rosell, 1972), E. porata (Nilsson-Cantell, 1921), E. zuiho (Hiro, 1936), and Acasta cyathus Darwin, 1854, which inhabit a wide range of sponges with various textures.

Ornate threadfin bream (Nemipterus hexodon) is an economically important fishery species in Southeast Asia. In Thailand, N. hexodon decreased dramatically due to overexploitation for commercial purposes. To construct an effective sustainable management plan, genetic information is necessary. Thus, in our study, the population genetic structure and demographic history of N. hexodon were investigated using 419 bp of the mitochondrial DNA sequence in cytochrome oxidase subunit I gene (mtDNA COI). A total of 142 samples was collected from nine localities in the Gulf of Thailand (Chonburi, Samut Songkhram, Surat Thani, Nakhon Si Thammarat, Songkhla), and the Andaman Sea (Satun, Trang, Krabi, Phang Nga). Fourteen polymorphic sites defined 18 haplotypes, revealing a high haplotype diversity and low nucleotide diversity among nine localities. The Analysis of molecular variance (AMOVA) analysis, pairwise FST, and minimum spanning network result revealed that the genetic structure of N. hexodon was separated into two populations: the Gulf of Thailand and the Andaman Sea population. The genetic structure of N. hexodon can be explained by a disruption of gene flow from the geographic barrier and the Pleistocene isolation of the marine basin hypothesis. Neutrality tests, Bayesian skyline analysis, mismatch distribution, and the estimated values of population growth suggested that N. hexodon had experienced a population expansion. The genetic information would certainly help us gain insight into the population genetic structure of N. hexodon living on the coast of Thailand.

The Thai commercial fleet can carry about 10% of the volume of imports and exports. History of Thai maritime trade is divided into 1) Sukhothai period era 2) Ayutthaya and Thonburi period 3) Rattanakosin period 4) The first of the national fleet period. .Sukhothai period era trade with various foreign countries. In the King Ramkhamhaeng era is a prosperous.. 1) The Gulf of Thailand trade with China 2) Trade on the Andaman sea is a merchant ship from India. Ayutthaya and Thonburi period. Traders of various nationalities come to trade. The Gulf of Thailand (South China Sea) and the Indian Ocean. Trading in Ayutthaya is a monopoly trade, operated by monarchs and noblemen.Rattanakosin period Thailand entered into a Treaty of Burney, the outcome of the agreement was that the country had to cancel its monopoly trade and the end of trade by the government. The growth of the trade has increased. The production structure from the old to be self-transformed into production for export. The first of the national fleet period 1918 - 1925 After the First World War I King Rama VI established a Thai merchant fleet in April 1918, the name of Siam Commercial Maritime Company Limited. It was terminated in 1925. On June 22, 1940, the cabinet approved the establishment of Thai Maritime Navigation Company Limited for international maritime shipping. The The cabinet was terminated in 2011 .The role of Thai National Maritime Navigation.The merchant fleet were not growing. Because lack of and thai merchant fleet too small, there was a lack of negotiating power with the foreign merchant fleet. The government must set up a policy to promote the merchant fleet.
