The experiment was carried out to determine the suitable level of dietary protein and fat in feed for optimal growth of Tor tambroides. FCR was being used to determine suitable protein dietary level while SGR was used to determine fat dietary level for optimum growth of the fish. There were signi ficant difference (P<O.O I) in feed consumption at different feed types. There were also significant different (P<O.O I) in the final length and final weight of the fish. The higher length increment was observed in fish fed with feed type C (1.49±0.00 cm) and the lowest was feed type B (0.45±O.00 cm). The higher weight increment was tish fed with feed type C (3 .23±0.00 g) and the lowest was type B (0.8612±0.00 g). The fish feed with feed type A showed the lowest FCR (4.28, 64.69%) followed by feed type B (5.94, 46.79%) and type C (9.38, 34.81%). Fish fed with feed type C (3.55%) showed the higher value ofSGR while the lowest value was feed type B (0.94%). ANOYA test showed that there were significant difference (P<O.OI) among the different type of feeds. In conclusion, the experiment showed that the optimum level of protein and fat jor the higher growth rate ofthe tish were 32% and 13% respectively.

This sh is part of an important group of freshwater cyprinids collectively known as mahseers that inhabit mountainous rivers and lakes of the Himalayan belt from Afghanistan to Indonesina and Myanmar. Mahseers form a signicant stock of indigenous sh in India, Nepal, Bangladesh and Pakistan with potential for the freshwater aquaculture industry. Malaysia’s three species of mahseer – T. tambroides, T. douronensis and T. tambra – live in headwaters and the fast- owing, cool and clear water of upland rivers. As with mahseers in other countries, the natural stock of Malaysian mahseers has rapidly declined in recent years due to environmental changes, human disturbance of aquatic ecosystems and overshing. Following the decline in populations of this species in the wild, its market prices rose as high as $80 and $240/kg when sold as food or ornamental sh, respectively.

  • Resolving Cypriniformes Relationships Using an Anchored Enrichment Approach Carla C
    Stout et al. BMC Evolutionary Biology (2016) 16:244 DOI 10.1186/s12862-016-0819-5 RESEARCH ARTICLE Open Access Resolving Cypriniformes relationships using an anchored enrichment approach Carla C. Stout1*†, Milton Tan1†, Alan R. Lemmon2, Emily Moriarty Lemmon3 and Jonathan W. Armbruster1 Abstract Background: Cypriniformes (minnows, carps, loaches, and suckers) is the largest group of freshwater fishes in the world (~4300 described species). Despite much attention, previous attempts to elucidate relationships using molecular and morphological characters have been incongruent. In this study we present the first phylogenomic analysis using anchored hybrid enrichment for 172 taxa to represent the order (plus three out-group taxa), which is the largest dataset for the order to date (219 loci, 315,288 bp, average locus length of 1011 bp). Results: Concatenation analysis establishes a robust tree with 97 % of nodes at 100 % bootstrap support. Species tree analysis was highly congruent with the concatenation analysis with only two major differences: monophyly of Cobitoidei and placement of Danionidae. Conclusions: Most major clades obtained in prior molecular studies were validated as monophyletic, and we provide robust resolution for the relationships among these clades for the first time. These relationships can be used as a framework for addressing a variety of evolutionary questions (e.g. phylogeography, polyploidization, diversification, trait evolution, comparative genomics) for which Cypriniformes is ideally suited.

They are the popular freshwater fish for food, ornamental and recreational fishing. However, their wild populations are now ecologically threatened as their numbers decline drastically over the years due to over-exploitation, natural habitat degradation and water pollution. With successful hatchery production, readily accepted artificial feed and fetched high market value, Malaysian mahseer is now considered a perspective for aquaculture. Stocks were collected from various sources for broodstock development to establish an appropriate base population with desirable characteristics that harbour adequate genetic diversity.

There are local fishes in the Banyu Biru called sengkaring and tambra. Biological studies on these fishes are not so much known. This study aims to identify the relationship of sengkaring and tambra compared with the related species (Tor spp.: Cyprinidae) from Indonesia. Morphometric analysis can be used to clustering and understanding the relationship of taxa. Each species represents 17 specimens (Tambra and Sengkaring) and measured 22 characters (in mm) by using digital caliper and the additional characters (21 characters). The canonical, clustering, similarity and distances were used. Based on morphometric measurements, sengkaring and tambra had similarity with the four species found in Indonesia. Currently, we are analyzing the deep relationship and identify the taxonomic of the two specimens using DNA Barcode COI and 16S

For this purpose, 40 specimens were obtained between December and March (2013). Muscle samples (without skin) taken from each fish were homogenized. Fat-soluble vitamins (A, D, E and K) and cholesterol were analysed simultaneously using HPLC (High-performance liquid chromatography) system. The fatty acids, grouped as saturated fatty acid (SFA), mono unsaturated fatty acid (MUFA) and polyenoic fatty acids (PUFA), were analysed by gas chromatography as the methyl esters. The results of present study showed that MUFA was the highest followed by SFA and PUFA. The highest fatty acid levels found in Shabut throughout all months (December – March) were 16:0, 18:1, 22:6 n-3 (DHA) and 20:5 n-3 (EPA). Shabut had low cholesterol level.

A total of 197 bands were generated by 16 RAPD primers with 87.73% polymorphic and 43.75% unique bands. Swat River’s population exhibited the highest level of polymorphism and held the highest genetic diversity (73%) followed by population of Mangla reservoir (57%), River Indus (54.31%), River Jhelum (44.67%), River Poonch (37.06%) and River Hingol (2.03%). Heterogeneity (Ht, 0.19), genetic diversity within population (Hs, 0.13), between populations (Dst, 0.05) and genetic differentiation constant (Gst, 0.022) were low. Gene flow between populations (3.22) was high. Analysis of Molecular Variance (AMOVA) ascribed higher variability (79%) within population factors. UPGMA dendrogram based on Nei’s genetic similarities and distances separated two main clusters of populations; cluster one subdivided into two; 1) were identified the populations of Poonch River, Jhelum River and Mangla Reservoir, and 2) swat River and Indus River.

These countries have a high diversity of freshwater fishes, especially described and undescribed species of Cypriniformes; together these species and other flora and fauna represent an extraordinary opportunity for worldwide collaboration to investigate the biodiversity, conservation, management and evolution of Borneo’s wildlife. Much of the fauna and flora of Borneo is under significant threat, warranting an immediate and swift international collaboration to rapidly inventory, describe, and conserve the diversity. The Sunda drainage appears to have been an important evolutionary centre for many fish groups, including cypriniforms (Cyprinidae, Balitoridae and Gyrinocheilidae); however, Northwestern Borneo (Brunei, Sabah and Sarawak) is not connected to Sundaland, and this disjunction likely explains the non-homogeneity of Bornean ichthyofauna. A previous study confirmed that northern Borneo, eastern Borneo and Sarawak shared a similar ichthyofauna, findings that support the general hypothesis for freshwater connections at one time between western Borneo and central Sumatra, and south Borneo and Java island.
