During this study six new records of fishes were observed under one order, three families, and four genera. According to the ichthyofauna checklist of Andaman & Nicobar Islands by Rao (2009), Ramakrishna et al. (2010) and Rajan et al. (2013), the fish species (Cheilodipterus isostigmus (Schultz, 1940), Cheilodipterus intermedius Gon, 1993, Ostorhinchus nigrofasciatus Lachner, 1953, Chlorurus capistratoides (Bleeker, 1847), Halichoeres richmondi Fowler & Bean, 1928, and Halichoeres cosmetus Randall & Smith, 1982 were added to the list of ichthyofauna of these islands.
Occurrence and distribution of tetraodontiform fishes of the Andaman and Nicobar Islands, India
Check List, 2018
Some fish groups are common on coral reefs, but we still lack fundamental information about how fish assemblages vary across seascapes. The order Tetraodontiformes, which includes pufferfish, triggerfish, shingles, porcupinefish, burrfish, leatherjacketfish, filefish, and trunkfish, is one such group. We systematically surveyed 75 sites around 52 islands of the Andaman and Nicobar archipelago to evaluate the occurrence and distribution of tetraodontiform fishes. We recorded 25 species from 16 genera and 6 families. We found the distribution of fishes to vary between sites and geographical regions, with the southern Nicobar region having higher species richness than other geographical regions in the island group. Possible reasons for the observed patterns of the occurrence and distribution of tetraodontiform fishes are discussed.
New records of rare marine fishes from the Gulf of Mannar India
The Gulf of Mannar is a haven for rare species, which along with their pristine reef habitats are under constant threat from natural phenomena and anthropogenic activities. Therefore, the presently reported study aimed at documenting and inventorying rare benthic epi-faunal taxa from the region. We undertook 23 bottom trawl hauls at depths between 14 and 153 m in the Gulf of Mannar. Additionally, we collected rare fishes from the Tuticorin fisheries jetty. Our findings revealed that Parapterois heterura (Bleeker, 1856) is a new record for the Indian waters. Additionally, four species namely Ebosia falcata Eschmeyer et Rama-Rao, 1977, Pseudanthias marcia Randall et Hoover, 1993, Apogon queketti Gilchrist, 1903, and Roa jayakari (Norman, 1939) are new records for the east coast of India outside their known geographical range, whereas five other teleosts (Ostichthys acanthorhinus Randall, Shimizu et Yamakawa, 1982, Apogon semiornatus Peters, 1876, Histiopterus typus Temminck et Schlegel, 1844,Macropharyngodon ornatus Randall, 1978, and Scolopsis xenochroa Günther, 1872) are new records for the east coast of India. The present paper supplements the existing knowledge of benthic invertebrate taxa from this region, which is mandatory to understand the role of these species in ecosystem functioning.
New records of marine fishes from the coral reefs and deep waters of Gulf of Mannar, India
Acta Ichthyologica et Piscatoria
Background. The coral reefs and deep water ecosystems of Gulf of Mannar support diverse assemblages of marine fishes vulnerable to indiscriminate mechanized fishing. However, lack of comprehensive information on the fish diversity of these ecosystems is aggravated by the habitat complexity of the fishing grounds, inadequate faunistic surveys and insufficient taxonomic expertise. In view of this, the present paper aims to document rare fishes and supplement the existing species inventory from this region. Materials and methods. Sampling surveys included 23 hauls on-board commercial single-day otter trawlers operating bottom trawls at 15-100 m depths, and mid-water trawls at 100-153 m depths in the Gulf of Mannar. In addition, by-catch landings of commercial trawlers were surveyed at Tuticorin fishing harbour. Specimens were subjected to morphometric and meristic examination and deposited at the Central Marine Fisheries Research Institute, Kochi. Results. The presently reported survey of rare fishes revealed one elasmobranch, Hypogaleus hyugaensis (Miyosi, 1939). In addition, 12 species of teleosts belonging to four orders, 10 families, and 11 genera were identified as
