A bstract The genetic characterization of catfishes by means of phenotypic markers, karyotyping, protein and DNA polymorphisms contributes to or forms an integral part of the disciplines of systematics, population genetics, quantitative genetics, biochemistry, molecular biology and aquaculture. Judged from the literature, the general approach to research is pragmatic; the Siluroidei do not include model species for fundamental genetic research. The Clariidae and the Ictaluridae represent the best studied families. The’ systematic status of a number of species and families has been either elucidated or confirmed by genetic approaches. Duplication of ancestral genes occurred in catfishes just as in other vertebrates. The genetic structure of and gene flow among natural populations have been documented in relatively few cases, while the evaluation of strains for aquaculture (especially Ictaluridae and Clariidae) is in progress. The mapping of genetic markers has started in Ictalurus. It appears that a more detailed knowledge of catfish populations is required from two perspectives. First, natural populations which are threatened by habitat loss and interfluvial or intercontinental transfers are poorly characterized at the genetic level. -

Walukow1, I Nyoman Sukarta2* 1 Physics Education Study Program, Departement of Mathematics and Natural Sciences, Faculty of Teacher and Education, University of Cenderawasih, Indonesia 2 Department of Chemistry, Faculty of Mathematic and Natural Sciences. Universitas Pendidikan Ganesha, Indonesia * Corresponding author’s email: [email protected] ABSTRACT The Simporo Strait is located in the Hendo River Basin. The erosion rate in the Hendo river basin is 12,434,881 m3/year, causing sediment discharge in the Hendo river by 0.00039 m3/year. The high rate of erosion and sediment discharge in the watershed resulted in siltation in the Simporo Strait. In addition to the silting problems, in the Simporo Strait there has also been pollution of the TSS, BOD and COD parameters. This research was conducted in the Simporo Strait with the aim of analyzing the carrying capacity of the Simporo Strait waters for drinking water, recreation, freshwater fish farming, animal husbandry, and water for irrigating crops. The research method uses the water carrying capacity analysis based on water pollution index. The results of the study concluded that the waters in the Simporo Strait have been polluted by TSS, BOD, COD and PO4, so they are not suitable for use as a source of drinking water (Class I) and for the purpose of recreation / tourism (Class II). -

EDITOR: Mrs Ajetomobi School of Agricultural Sciences Lagos State Polytechnic Ikorodu, Lagos 2 BIO 313 COURSE GUIDE Introduction Animal Ecology (313) is a first semester course. It is a two credit unit elective course which all students offering Bachelor of Science (BSc) in Biology can take. Animal ecology is an important area of study for scientists. It is the study of animals and how they related to each other as well as their environment. It can also be defined as the scientific study of interactions that determine the distribution and abundance of organisms. Since this is a course in animal ecology, we will focus on animals, which we will define fairly generally as organisms that can move around during some stages of their life and that must feed on other organisms or their products. There are various forms of animal ecology. This includes: • Behavioral ecology, the study of the behavior of the animals with relation to their environment and others • Population ecology, the study of the effects on the population of these animals • Marine ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment). -

Food and Feeding Habit of the Critically Endangered Catfish Rita Rita (Hamilton) from the Padda River in the North-Western Region of Bangladesh
International Journal of Advancements in Research & Technology, Volume 2, Issue 1, January-2013 ISSN 2278-7763 Food and feeding habit of the critically endangered catfish Rita rita (Hamilton) from the Padda river in the north-western region of Bangladesh Syeda Mushahida-Al-Noor1*, Md. Abdus Samad1 and N.I.M. Abdus Salam Bhuiyan2 1Department of Fisheries, Faculty of Agriculture, University of Rajshahi, Rajshahi 6205, Bangladesh. 2Department of Zoology, Faculty of Life and Earth, University of Rajshahi, Rajshahi 6205, Bangladesh. *E-mail: [email protected] ABSTRACT Food and feeding habits of Rita rita collected from the Padda river in the north-western region of Bangladesh were investigated by examining the gastro-intestine contents of 744 specimens collected from May, 2010 to April, 2011. Their diet consisted of a broad spectrum of food types but crustaceans were dominant, with copepodes constituting 20.73%, other non-copepode crustaceans constituted 12.01%. The next major food group was insect (15.97%), followed by mollusks (14.76%), teleosts (12.98%) and fish eggs (8.608%). Food items like Teleosts, mollusks, insects and shrimps tended to occur in the stomachs in higher frequencies with an increase in R. rita size (up to 30.5 - 40.5cm), while fish eggs, copepods and non-copepode crustaceans tended to increase in stomachs at sizes between 10.5-20.5cm. Analysis of monthly variations in stomach fullness indicated that feeding intensity fluctuated throughout the year with a low during June and August corresponding to the spawning period. Keywords: Rithe, food items, feeding frequency, Ganges, Rajshahi. 1 INTRODUCTION mollusks, fishes and rotifers in adult stage (Bhuiyan, 1964 and Rita rita (Hamilton) is a freshwater fish and commonly known Rahman, 2005) but takes insects and aquatic plants in earlier as catfish. -

Review of Inland Fisheries in Netherlands New Guinea
RESTRICTED SPC/FTM/Tech. 9 1 February 1962 SOUTH PACIFIC COMMISSION FISHERIES TECHNICAL MEETING (Noumea, 5-13 February 1962) REVIEW OF INLAND FISHERIES IN NETHERLANDS NEW GUINEA Paper prepared by Mr. J. de VRIES, Chief Inland Fisheries Officer, Department of Economic Affairs, Hollandia, Netherlands New- Guinea. I. INTRODUCTION A. GENERAL As in many other countries, the government of Netherlands New Guinea has undertaken the comprehensive task of promoting and developing the territorial fisheries in co-operation with the Food and Agricultural Organization of the United Nations and the South Pacific Commission. So far as the Inland Fisheries Section is concerned, this task comprises in the main the operation of fisheries in open waters (lakes, swamps, rivers) and pisciculture in ponds and other suitable inland waters. The fundamental problems in this field were: a) knowledge of the indigenous fish varieties that may have economic value; b) knowledge of the fish stocks; c) research into the ecological conditions in which the fish stocks occur. B. INDIGENOUS FISH VARIETIES The first-mentioned problem - fish varieties - has been the subject of intensive studies of BLEEKER, DE BEAUFORT, MAX VffiBER, MUNRO, BOESEMAN, and others. Their researches revealed that among the locally found ATHERINIDAE, MUGILIDAE, LUTJANIDAE, APOGONIDAE, ARRIDAE, GOBIIDAE, ELECTRIDAE, PLEURONECTOIDES, and ELASMOBRANCHIDAE, there were few varieties of actual economic value. Only MUGILIDAE, which species was hot being fished for with the primitive equipment used, and LUTJANIDAE, could be regarded as species of possible economic signific ance. Catches of LUTJANUS JOHNII on Lake Sentani alone total 6£ metric tons annually. Improved fishing methods may raise this production to 12 metric tons. -
