Section 4 deals with the results of was from Asia in 2001. In this region, there are the producer survey conducted by the WorldFish more than 20 main native carp species, Center and its partner institutions. This includes a contributing about 80 per cent of the total description of the profile of carp producers freshwater fish production.

Date: December 2020 Copyright © 2020 Stellenbosch University All Rights Reserved i Stellenbosch University https://scholar.sun.ac.za Abstract: Labeo spp. are large freshwater fish found throughout southern Asia, the Middle East and Africa. The genus is characterised by specialised structures around the mouth and lips making it adapted to herbivorous feeding (algae and detritus). Clanwilliam sandfish (Labeo seeberi) was once widespread throughout its natural habitat (Olifants-Doring River system), but significant decreases in population size have seen them become absent in the Olifants River and retreat to the headwaters in the tributaries of the Doring River. Currently sandfish are confined to three populations namely the Oorlogskloof Nature Reserve (OKNR), Rietkuil (Riet) and Bos, with OKNR being the largest of the three and deemed the species sanctuary.

  • Carp Dominate Fish Communities Managing the Impacts of Carp Throughout Many Waterways in South- Eastern Australia
    Managing the Impacts of Introduced carp dominate fish communities the Impacts of Carp Managing throughout many waterways in south- eastern Australia. They also occur in Carp Western Australia and Tasmania and have the potential to spread through many more of Australia’s water systems. Carp could eventually become widespread throughout the country. Carp are known to damage aquatic plants and increase water turbidity but their impacts on native fish species are not yet clear. Carp are also a commercial and recreational fishing resource. Managing the Impacts of Carp provides a comprehensive review of the history of carp in Australia, their biology, the damage they cause and community attitudes to these problems and their solutions. Key strategies for successful carp manage- ment are recommended by the authors who are scientific experts in carp manage- ment. These strategies are illustrated by case studies. Managing the Impacts of Carp is an essential guide for policy makers, land and water managers, carp fishers and all others interested in carp management.

  • The Role of Species and Systems in the Development and Growth of Aquaculture in Asia: Needs and Prospects Mahfuzuddin Ahmed, Madan Mohan Dey, and Yolanda T
    Species & System Selection: For Sustainable Aquaculture Edited by PingSun Leung, Cheng-Sheng Lee, Patricia J. O’Bryen Copyright © 2007 by Blackwell Publishing Part 2 Practices Species & System Selection: For Sustainable Aquaculture Edited by PingSun Leung, Cheng-Sheng Lee, Patricia J. O’Bryen Copyright © 2007 by Blackwell Publishing Chapter 7 The Role of Species and Systems in the Development and Growth of Aquaculture in Asia: Needs and Prospects Mahfuzuddin Ahmed, Madan Mohan Dey, and Yolanda T. Garcia Abstract During the previous three decades aquaculture development in Asia was characterized by a broad spec- trum of users, systems, practices, and species through a continuum ranging from backyard household operations to industry-scale commercial systems. These systems produced the largest quantities of affordable food fish for domestic markets and home consumption in the world, making aquaculture one of the fastest growing food-producing subsectors in the region. With a steady growth of 9–11% per annum, Asia’s aquaculture constitutes 90% of the global farmed fish output. Urbanization, a rising middle class, and growth of export trade have had a major impact on the choice of species and systems, including postharvest technologies. This paper reviews the current practices in Asian aquaculture and emerging trends in species and sys- tems against a backdrop of changing structure of demand, supply, and trade. It examines key issues con- cerning the role of aquaculture as an engine for economic growth in rural areas of developing Asia. Taking examples from South and Southeast Asia, the paper also analyzes the prospects and needs of the sector by identifying key technological, socioeconomic, and policy factors that will enhance its role in providing animal protein, employment, income, and foreign exchange to the economy and its population.

  • 1. Introduction
    1 1. INTRODUCTION Catla catla is endemic to the riverine system in northern India, Indus plain and adjoining hills of Pakistan, Bangladesh, Nepal and Myanmar has been introduced later into almost all riverine systems, reservoirs and tanks all over India. As the species breeds in the riverine ecosystem, its ready seed availability has helped in establishing its aquaculture in the peripheral region of the riverine system in these countries. The natural distribution of catla seems to be governed by temperature dependency rather than latitude and longitude. The minimum tolerance temperature limit is 14 °C. The use of catla as a component in pond culture was a traditional practice in the eastern Indian states, spreading to all other Indian states only during the second half of the 20th century. Its higher growth rate and compatibility with other major carps, specific surface feeding habit, and consumer preference have increased its popularity in carp polyculture systems among the fish farmers in India, Bangladesh, Myanmar, Laos, Pakistan and Thailand. The collection of riverine seed was the only source for culture until the 1950s. Success in the induced breeding of the species in 1957 assured subsequent seed supply, thus revolutionising this form of polyculture in India and other south-east Asian countries. The species has also been introduced elsewhere, including Sri Lanka, Israel, Japan, and Mauritius. At present, catla forms an integral component species, both in three-species polyculture with rohu (Labeo rohita) and mrigal (Cirrhinus mrigala), and six-species composite carp culture, which adds common carp (Cyprinus carpio), grass carp (Ctenopharyngodon idellus) and silver carp (Hypophthalmichthys molitrix) (Lamarra, 1975; Cooper, 1987; Koehn et al.,2000).

First records of scale deformities in seven freshwater fi sh species (Actinopterygii: Percidae and Cyprinidae) collected from three ponds in the Czech Republic. Acta Ichthyol. Piscat. 46 (3): 225–238. Background. A wide range of morphological anomalies, including abnormalities in scale shape and structure, have been described from a large number of fi sh species worldwide. Quite often, such reports linked the observed abnormalities to the quality of aquatic environment. The presently reported study was initiated to explore and categorize the abnormalities found in the scales of seven freshwater fi sh species of Czech Republic: Ctenopharyngodon idella (Valenciennes, 1844); Gymnocephalus cernua (Linnaeus, 1758); Hypophthalmichthys molitrix (Valenciennes, 1844); Hypophthalmichthys nobilis (Richardson, 1845); Leuciscus idus (Linnaeus, 1758); Perca fl uviatilis Linnaeus, 1758; and Sander lucioperca (Linnaeus, 1758). The observed abnormalities are discussed in the context of contaminated aquatic environments with the intention to understand the aetiology of the abnormalities Materials and methods.
