Omni-Akuatika, 13 (1): 54–59, 2017 ISSN: 1858-3873 print / 2476-9347 online Research Article Model of Profit Maximization of the Giant Gourami (Osphronemus goramy) Culture Dian Wijayanto1*), Faik Kurohman1, Ristiawan Agung Nugroho1 1Fakultas Perikanan dan Ilmu Kelautan Universitas Diponegoro *Corresponding author: [email protected] Received 7 November 2016; Accepted 16 April 2017; Available online 31 May 2017 ABSTRACT This research’ objective is to develop a model of profit maximization that can be applied to the giant gourami culture. The development of fish growth model uses polynomial growth function. Profit maximization process uses the first derivative of profit equation to culture time equal to zero. This research develop the equations to estimate the culture time to reach the size target of cultured fish. This research model can be applied in the giant gouramy culture. The giant gouramy culture can produce the maximum profit at 324 days with profit of IDR. 7.847.700 per culture cycle. To achieve size target of 500 g per fish, it needs 135 days of culture time.

Aliens; a Catastrophe for Native Fresh Water Fish Diversity in Pakistan
The Journal of Animal and Plant Sciences, 21(2 Suppl.): 2011, Page: 435-440 ISSN: 1018-7081 ALIENS; A CATASTROPHE FOR NATIVE FRESH WATER FISH DIVERSITY IN PAKISTAN A. M. Khan, Z. Ali, S. Y. Shelly* Z. Ahmad** and M. R. Mirza** Department of Zoology, University of the Punjab, Lahore *Department of Fisheries, Government of Punjab, Munawan, Lahore. Department of Zoology, Government College University, Lahore Corresponding author e-mail: [email protected] ABSTRACT Pakistan has introduced several alien exotic fish species e.g. grass carp (Ctenopharyngodon idella), bighead carp, (Hypophthalmichthys nobilis), silver carp, (Hypophthalmichthys molitrix), common carp (Cyprinus carpio), gold fish (Carassius auratus), and three species of tilapia (Oreochromis aureus, Oreochromis mossambicus, Oreochromis niloticus) in warm waters along with two trout species: the rainbow trout (Onchorynchus mykiss) and the brown trout (Salmo trutta fario) in colder regions for specific purposes like sport fishing, yield enhancement and biological control of aquatic weeds and mosquitoes. The exotic species are becoming invasive in the freshwater biomes of the Punjab and other provinces of Pakistan by reason of their potent reproductive potential and feeding competitions with the native freshwater fish fauna. Resultantly the native fish species viz; Channa marulius, Wallago attu, Rita rita, Sperata sarwari, Gibelion catla, Cirrhinus mrigala and Labeo rohita, which are of economic value are under threat. Key words: Exotic, invasions, freshwater, fish fauna, Pakistan. wild, 421 (35 %) are reported as not established and 177 INTRODUCTION (15 %) with unknown establishment (Fish base, 2003).

FLOODPLAIN RIVER FOOD WEBS IN THE LOWER MEKONG BASIN A Dissertation by CHOULY OU Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Kirk O. Winemiller Committee Members, Masami Fujiwara Thomas D. Olszewski Daniel L. Roelke Head of Department, Michael Masser December 2013 Major Subject: Wildlife and Fisheries Sciences Copyright 2013 Chouly Ou ABSTRACT The Mekong River is one of the world’s most important rivers in terms of its size, economic importance, cultural significance, productivity, and biodiversity. The Mekong River’s fisheries and biodiversity are threatened by major hydropower development and over-exploitation. Knowledge of river food web ecology is essential for management of the impacts created by anthropogenic activities on plant and animal populations and ecosystems. In the present study, I surveyed four tropical rivers in Cambodia within the Mekong River Basin. I examined the basal production sources supporting fish biomass in the four rivers during the dry and wet seasons and explored the relationship between trophic position and body size of fish at various taxonomic levels, among local species assemblages, and across trophic guilds. I used stable isotopes of carbon and nitrogen to estimate fish trophic levels and the principal primary production sources supporting fishes. My study provides evidence that food web dynamics in tropical rivers undergo significant seasonal shifts and emphasizes that river food webs are altered by dams and flow regulation. Seston and benthic algae were the most important production sources supporting fish biomass during the dry season, and riparian macrophytes appeared to be the most important production source supporting fishes during the wet season. -
Growth Performance and Survival Rate of Giant Gourami Fingerlings (Osphronemus Goramy Lacepede, 1801) with Potassium Diformate Addition
Available online at www.worldscientificnews.com WSN 143 (2020) 103-114 EISSN 2392-2192 Growth performance and survival rate of giant gourami fingerlings (Osphronemus goramy Lacepede, 1801) with potassium diformate addition Algi Azmi Nugraha*, Ayi Yustiati, Ibnu Bangkit, Yuli Andriani Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Bandung – Sumedang KM.21 Jatinangor 45363, Indonesia *E-mail address: [email protected] ABSTRACT This research aims to determine the method of adding potassium diformate to commercial feed to increase survival and growth in gourami juvenile. The method used in this research is an experimental method using a Completely Randomized Design (CRD), consists of four treatments and four replications. The treatments used are (A) Without giving Potassium diformate (control), (B) giving potassium diformate by 0.3%, (C) giving potassium diformate by 0.5% and (D) giving potassium diformate by 0.8%. The test fish used was 300 giant gourami with a length of 4-6 cm. The containers used in this research were aquariums with a size of 40 × 30 × 40 cm3 that reared in 16 aquariums. The density of giant gourami fingerlings during the research was 10 fish per aquarium. The rearing period was 40 days. The feed given was 3% of body mass. Water quality parameters (temperature, pH and dissolved oxygen) were observed every 10 days. Other parameters are the daily growth rate, feed efficiency, the survival rate and the acidity of intestinal and stomach which were observed every 10 days. The results showed that the addition of potassium diformate by 0.3% gives the best results of daily growth rate of 1.31%, feeding efficiency of 37.18%, survival rate of 100% and decreased acidity in the intestine and stomach which helps in the process of protein absorption. -

SCIENCE CHINA Phylogenetic Relationships and Estimation Of
SCIENCE CHINA Life Sciences • RESEARCH PAPER • April 2012 Vol.55 No.4: 312–320 doi: 10.1007/s11427-012-4305-z Phylogenetic relationships and estimation of divergence times among Sisoridae catfishes YU MeiLing1,2* & HE ShunPing1* 1Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 400732, China; 2Graduate University of Chinese Academy of Sciences, Beijing 100049, China Received December 10, 2011; accepted March 9, 2012 Nineteen taxa representing 10 genera of Sisoridae were subjected to phylogenetic analyses of sequence data for the nuclear genes Plagl2 and ADNP and the mitochondrial gene cytochrome b. The three data sets were analyzed separately and combined into a single data set to reconstruct phylogenetic relationships among Chinese sisorids. Both Chinese Sisoridae as a whole and the glyptosternoid taxa formed monophyletic groups. The genus Pseudecheneis is likely to be the earliest diverging extant ge- nus among the Chinese Sisoridae. The four Pareuchiloglanis species included in the study formed a monophyletic group. Glaridoglanis was indicated to be earliest diverging glyptosternoid, followed by Glyptosternon maculatum and Exostoma labi- atum. Our data supported the conclusion that Oreoglanis and Pseudexostoma both formed a monophyletic group. On the basis of the fossil record and the results of a molecular dating analysis, we estimated that the Sisoridae diverged in the late Miocene about 12.2 Mya. The glyptosternoid clade was indicated to have diverged, also in the late Miocene, about 10.7 Mya, and the more specialized glyptosternoid genera, such as Pareuchiloglanis, originated in the Pleistocene (within 1.9 Mya). The specia- tion of glyptosternoid fishes is hypothesized to be closely related with the uplift of the Qinghai-Tibet Plateau. -

Small ornamental species are mostly preferable in aquarium industry. BK Mahapatra Gourami is one of the most valuable and popular in small ornamental fish world. In India presently 8 ICAR-Central Institute of indigenous Gourami species are very common and highly demanding. Ctenops nobilis is one of the Fisheries Education, Salt Lake highly demanding and important among the 8 indigenous Gourami species. It is the only known species City, Kolkata, India in its genus. The fish is mainly cold water species. The species is widely distributed but it is a naturally scarce species. As per IUCN Red list, 2010 status the species is assessed as Near Threatened for its J Maity Vidyasagar University, population declines in the wild. Very little data available of the fish resulting problems occur during Midnapore, West Bengal, India maintenance of the fish in aquarium. So the proper study on the fish, captive breeding and rearing procedure of the fish is very important to meet the increasing demand of the fish among aquarium hobbyist.
