Abstract

The feeding habits of the endemic cyprinid fish, Hypselobarbus thomassi (Day, 1874) was studied based on the monthly sampling in the Kallada River, Kerala, India from April 2010 to March 2011. Gut contents of 183 fish specimens were analysed and quantified using occurrence and volumetric methods. Analysis of the gut contents showed that semi-digested plant matter (22.11%) was the most preferred food item of the fish followed by Bacillariophyceae (19.80%), Chlorophyceae (19.38%), semi-digested animal matter (11.21%), soil particles (9.20%), seeds of plants (6.70%), Cyanophyceae (5.51%) and miscellaneous items (6.08%). The results indicated that H. thomassi is an omnivorous-stenophagic-column feeder. The gastrosomatic index (GaSI) ranged from 3.28-7.33 with an increment from August to November coincides with the spawning season and energy preservation for gonadal development. The information on feeding ecology of H. thomassi , a critically endangered fresh water fish from Western Ghats biodiversity hotspot would be useful towards formulating proper conservation plan for the species in its natural range.

印度喀拉拉邦Kallada河的特有鱼Hypselobarbus thomassi (Day, 1874)的食物和摄食习性
根据2010年4月至2011年3月在印度喀拉拉邦卡拉达河的月度采样,研究了特有的塞浦路斯鱼类Hypselobarbus thomassi(Day,1874)的食性。采用产状和体积法对183个鱼类标本的肠道内容物进行了分析和定量。对肠道内容物的分析表明,半消化的植物物质(22.11%)是鱼类最喜欢的食物,其次是硅藻科(19.80%)、吊兰科(19.38%)、半消化的动物物质(11.21%)、土壤颗粒(9.20%)、植物种子(6.70%),蓝藻科(5.51%)和杂项(6.08%)。胃体细胞指数(GaSI)在3.28-7.33之间,从8月到11月增加,恰逢产卵季节和性腺发育的能量保存。来自西高止山脉生物多样性热点的极度濒危淡水鱼H.thomassi的觅食生态学信息将有助于为其自然范围内的物种制定适当的保护计划。

期刊介绍: Iranian Journal of Ichthyology (IJI) is a peer-reviewed journal for publication of high quality papers on any aspect of ichthyology and will be published 4 times a year by the Iranian Society of Ichthyology (http://www.isi-org.ir). The journal welcomes the submission of manuscripts that meets the general criteria of significance and scientific excellence, and will publish original scientific articles in the fields of ichthyology. The editors welcome the submission of original manuscripts including Research Articles, Short communications, and Views & News. Review papers by distinguished authors and Special Issues will also be considered. It is our aim to provide the international scientific community with an efficiently published journal, meeting high scientific and technical standards. Scopes of Iranian Journal of Ichthyology includes: Systematics, taxonomy, morphology, anatomy, biogeography, biodiversity, conservation, ecology and general biology of fishes (reproduction, food and feeding habits, age and growth, population dynamics, etc.). Papers on freshwater, brackish, marine and fossil fishes will be considered.
