Abrief review of recent ichthyological research and compiled results on the records of fishes from the Andaman Sea coast of Thailand are presented. A total of 1,746 species in 198 families of fishes are currently known from the area. The 10 most speciose families are the Gobiidae (227 species), Labridae (78), Pomacentridae (71), Serranidae (61), Apogonidae (60), Blenniidae (52), Carangidae (52), Scorpaenidae (49), Lutjanidae (39) and Chaetodontidae (37), and these together account for 42% of the total fish fauna. The ichthyofauna is dominated by reef-associated fishes (983 species) and pelagic/benthic fishes inhabiting offshore habitats (971 species).Azoogeographic analysis reveals a peculiarity of the fauna of this marginal-sea region, viz., being one of the areas of sympatry of Indian and Pacific Ocean fishes, as well as harbouring regional endemics. The PMBC Reference Collection currently contains examples of only about 63% of the fishes known from the area, indicating a need for further local sampling campaigns and/or international collaborative exploratory research programs in theAndaman Sea to build up the Reference Collection.

The trophic response of the scleractinian coral Pocillopora meandrina (Dana, 1846) to large amplitude internal waves (LAIW) was investigated in the Andaman Sea. Corals living on the western sides of the Similan Islands (Thailand) exposed to LAIW showed significantly higher biomass and protein content than sheltered corals on the eastern sides. LAIW-exposed corals were also more heterotrophic, displaying lower δ13C ratios in their tissues and higher rates of survival in artificial darkness compared to sheltered counterparts. Heterotrophic nutrition in concert with photosynthesis leads to higher energy reserves in corals from LAIW-exposed reefs, making them more resilient to disturbance. As these differences in trophic status are due to LAIW-enhanced fluxes of organic matter, LAIW may play an important role in supporting coral metabolism and survival in these monsoon beaten reefs. © Inter-Research 2010, www.int-res.com.

A new worm eel, Neenchelys andamanensis, is described based on a single specimen collected from a depth of 520-531 m, Andaman Sea, eastern Indian Ocean. The new species is similar to N. daedalus, N. nudiceps, and N. similis in its total vertebral count and slender body, however, it differs from the latter three in having a shorter tail (60% TL vs. 70-76%), more numerous preanal vertebrae (77 vs. 59-71), and shorter pectoral fins (2.4% HL vs. 21-27%). Although the new species resembles N. mccoskeri in some proportional characters, the former species is distinguishable from the latter by its higher total vertebral count (221 vs. 172-184), position of the dorsal-fin origin (horizontal distance from the origin to a vertical through mid-anus 65% of trunk length vs. 46-59%) and width of the interorbital region (4.5% of head length vs. 8.2-16%). A revised key to the species of Neenchelys is provided. © 2015 Magnolia Press.

Sea temperature is one of the most important parameters influencing marine organisms in the tropics. There is high inter-annual variation in sea surface temperature (SST) in the Bay of Bengal with two maxima each year. High SSTs normally occur in April and October which are the transition monsoon periods with the highest temperatures being recorded in April. During the last decade, high SSTs occurred in 2003-2005 with particularly high values (around 32°C) in 2010. Coral bleaching was noted during these high SST years especially in 2010 which was the most severe mass coral bleaching ever recorded on the Andaman Sea coast of Thailand. Observations of SST in coastal waters and in the Central of Bay of Bengal appear to match each other quite well. The inter-annual variation of SST in the Bay of Bengal could be influenced by large scale oceanographic processes in the Indian Ocean such as the Indian Ocean Dipole (IOD) and El Nino.

The 2004 tsunami left a discontinuous pattern of destruction in the reefs along Andaman Sea coast of Thailand. Here, a comparative assessment of coral recruitment was carried out to assess differences in recovery between damaged and undamaged sites in near-shore fringing reefs 1 and 3 years after the tsunami. Settlement plates showed high frequencies of coral spat after 4 months (<17 spat tile-1) in both, damaged and undamaged locations. Field surveys carried out 3 years after the tsunami on natural substrate confirmed that tsunami damage did not suppress recruitment in damaged sites relative to no impacted controls. New and stable settlement space along with unabated larval supply supported post-tsunami recruit densities up to 7.2 m-2year-1. Mean recruit densities were found at the level of post-storm situations with rapid recovery success, suggesting that the duration of disturbance, degree of sorting and, hence, stability of coral rubble is a key determinant of recruitment success. Low regeneration success of some species e.g. branching acroporids and rebounding tourism industry at sites like Patong and partly around the Phi Phi Islands (dense carpets of filamentous algae) led to the assumption of selectivity and eventually to an alternation of the coral community even though live coral cover might be recovered soon. © 2010 Springer-Verlag and AWI.
