ABSTRACT Arunachal Pradesh once described as the “Hidden Land” by virtue of its geographical position, climatic conditions and altitudinal variations is a biodiversity rich region in the top of the North-Eastern part of India. The entire state is almost wholly a rugged mountainous terrain, with beautiful green valleys drained by innumerable streams, rivulets descending down from high elevation to the plains of Assam to meet the mighty river Brahmputra. There are 28 different identified fish species of Microphis (pipefish and sea horses) under family Sygnathidae, both freshwater and marine which are reported from various geographical corners of the world. Out of which five species are reported in freshwater system in Asian continent and only one species Microphis deocatus was reported previously from India. The finding of Doryichthys Martensii or Microphis ignoratus from Arunachal Pradesh, India is a new record not only from India but also from Indian sub-continent.

Animal-based traditional medicine not only plays a signifcant role in therapeutic practices worldwide but also provides a potential compound library for drug discovery. However, persistent hunting and illegal trade markedly threaten numerous medicinal animal species, and increasing demand further provokes the emergence of various adulterants. As the conventional methods are difcult and time-consuming to detect processed products or identify animal species with similar morphology, developing novel authentication methods for animal-based traditional medicine represents an urgent need.

  • Sound Signatures and Production Mechanisms of Three Species of Pipefishes (Family: Syngnathidae)
    Sound signatures and production mechanisms of three species of pipefishes (Family: Syngnathidae) Adam Chee Ooi Lim1, Ving Ching Chong1, Chiow San Wong2 and Sithi Vinayakam Muniandy2 1 Institute of Biological Sciences, Faculty of Science, Universiti Malaya, Kuala Lumpur, Wilayah Persekutuan, Malaysia 2 Department of Physics, Faculty of Science, Universiti Malaya, Kuala Lumpur, Wilayah Persekutuan, Malaysia ABSTRACT Background. Syngnathid fishes produce three kinds of sounds, named click, growl and purr. These sounds are generated by diVerent mechanisms to give a consistent signal pattern or signature which is believed to play a role in intraspecific and interspecific communication. Commonly known sounds are produced when the fish feeds (click, purr) or is under duress (growl). While there are more acoustic studies on seahorses, pipefishes have not received much attention. Here we document the diVerences in feeding click signals between three species of pipefishes and relate them to cranial morphology and kinesis, or the sound-producing mechanism. Methods. The feeding clicks of two species of freshwater pipefishes, Doryichthys martensii and Doryichthys deokhathoides and one species of estuarine pipefish, Syngnathoides biaculeatus, were recorded by a hydrophone in acoustic dampened tanks. The acoustic signals were analysed using time-scale distribution (or scalogram) based on wavelet transform. A detailed time-varying analysis of the spectral contents of the localized acoustic signal was obtained by jointly interpreting the oscillogram, scalogram and power spectrum. The heads of both Doryichthys species were prepared for microtomographical scans which were analysed using a 3D Submitted 12 September 2015 imaging software. Additionally, the cranial bones of all three species were examined Accepted 12 November 2015 using a clearing and double-staining method for histological studies.

Sulawesi is the largest island of the Wallacea. Here, we present an annotated checklist of fish species record- ed in Sulawesi’s inland waters. We recognize a total of 226 species from 112 genera and 56 families. Gobiidae (41 species), Adrianichthyidae (20 species) and Telmatherinidae (19 species) are most species-rich, making up a total of 43% of the total species diversity. 65 species are endemic to Sulawesi’s freshwaters, including 19 Tematherinidae, 17 Adrianichthyi- dae, and 17 Zenarchopteridae. 44% of the inland fish fauna are obligate freshwater fishes, followed by euryhaline (38%) and amphi-, ana- or diadromous (29%) taxa. 65 species have been recorded from lacustrine environments. However, we stress that the data available are not representative for the island’s freshwater habitats. The fish species diversity of the spectacular lakes is largely explored, but the riverine ichthyofaunas are in clear need of further systematic exploration.

Sampled individuals were evaluated for weight, seven meristic Lentic environment, Lotic environments, characters, and 16 morphometric characters. Multivariate methods viz., permutational Meristic characters, multivariate ANOVA, principal component analysis and linear discriminant function Morphometric characters, analysis were applied for stock discrimination. The length-weight relationship and Multivariate methods condition factor were also examined. Results: The sample of D. boaha comprised 297 individuals from Songkhla Lake and 110 from Bangpakong River. Permutational multivariate ANOVA revealed significant differences by sex and environment (p < 0.05). Except for tail length, morphometric and meristic characters all showed high loadings to the principal component axes. The linear discriminant function analysis predicted high accuracy in separating the two stocks. However, low success in prediction was found when using the meristic characters to distinguish the samples in combination of sex and environment.

In fish-based studies, the failure to recognize fishes as distinct biological units can lead to wrong diagnosis. Hence, this review paper attempts to clarify and discuss the latest schools of thought pertaining to fish taxonomy and the techniques for species identification. It is hoped that the contents and illustrations in this paper will assist researchers in laying a good foundation to inform their studies.

Diagnoses of a new genus and 64 new species of fishes from Laos (Teleostei: Cyprinidae, Balitoridae, Bagridae, Syngnathidae, Chaudhuriidae and Tetraodontidae) Maurice Kottelat * * Route de la Baroche 12, Case postale 57, CH-2952 Cornol, Switzerland address for correspondence); and Department of Biological Sciences, National University of Singapore, Kent Ridge, Singapore 119260. Email: [email protected] Abstract A new genus (Laocypris) and 64 new species of fishes are described from Laos. The new species belong to the genera Acrossocheilus (1), Crossocheilus (1), Danio (3), Garra (1), Laocypris (1), Mystacoleucus (1), Poropuntius (4), Puntius (1), Rasbora (2) (Cyprinidae), Hemimyzon (2), Homaloptera (1), Schistura (39), Sectoria (1), Vanmanenia (2) (Balitoridae), Pseudomystus (1) (Bagridae), Doryichthys (1) (Syngnathidae), Chauduria (1) (Chaudhuriidae) and M onotrete (1) (Tetraodontidae). Introduction Fish surveys conducted in Laos between 1996 and 1999 It could be argued that this approach to taxonomy have increased the number of species known in the is no longer acceptable, arguably being reminiscent country from some 210 recorded in the literature as at of work done in the 1930s or even in the 19th century. 1996 to 481 (15 of them not native to the country) However, our knowledge of the fish fauna of Laos is recognized in a just-completed field guide (Kottelat, far inferior to what was known of most tropical faunas 2000a). Several of the species discovered during these in the 1930s.
