The antiseptic movement of LAM was appraised against Streptococcus (spherical Gram-positive bacteria belonging to the phylum Firmicutes). The results designated that the improved LAM isolates from intestine of Mango tilapia and Cyprinus carpio were 16 (32%) and 6 (12%), separately. LAM are at its essential Lactobacillus, Leuconostoc, Pediococcus, Lactococcus, and Streptococcus, as well as the more exterior Aerococcus, Carnobacterium, Enterococcus, Oenococcus, Sporolactobacillus, Tetragenococcus, Vagococcus, and Weissella.

  • Genetic Resources for Aquaculture: Status and Trends
    109 Genetic resources for aquaculture: status and trends Roger S.V. Pullin 7A Legaspi Park View, 134 Legaspi Street, Consultant, Philippines 1. SUMMARY Aquaculture, the farming of aquatic plants and animals, has grown consistently since 1970, when it provided only 3.9 percent of world fish supply. In 2004, global production of farmed fish (mainly crustaceans, molluscs and finfish) was over 45 million tonnes, comprising about 32 percent of total world fish supply, while the total production of farmed seaweeds for food and extraction of chemicals, was about 13.9 million t. Aquaculture also provides increasing proportions of the world’s supply of ornamental aquatic organisms. Over 90 percent of aquaculture takes place in developing countries, where it has high importance for poor people in terms of nutrition and livelihoods and where further responsible development of aquaculture, integrated with other natural resource use, has high potential for future growth. Based upon statistics submitted to FAO by its member States, about 84 percent of farmed fish production comes from Asia, with 67 percent coming from the Peoples’ Republic of China. However, aquaculture is increasing in importance in all developing regions and is expected to provide about 50 percent of world food fish supply within the next 20 years. The future of aquaculture will depend in large measure upon the effective management of the genetic resources for farmed aquatic plants (PGR) and farmed fish (FiGR), as well as those for the organisms that provide their food and ecosystem services. Fish farms are agroecosystems and aquatic genetic resources for aquaculture on farms are part of agrobiodiversity.

To optimise crop yield, the cocoa trees require spraying with neonicotinoid insecticides (Imidacloprid, Thiacloprid Acetamiprid and Thiamethoxam). It is proposed that rainwater runoff from the treated area may pollute the Owena River and that these pesticides may thereby enter the human food chain via six species of fish (Clarias gariepinus, Clarias anguillaris, Sarotherodon galilaeus, Parachanna obscura, Oreochromis niloticus and Gymnarchus niloticus) which are cultured in the river mostly for local consumption.

DOI: 10.1002/aqc.699 The effects of introduced tilapias on native biodiversity GABRIELLE C. CANONICOa,*, ANGELA ARTHINGTONb, JEFFREY K. MCCRARYc,d and MICHELE L. THIEMEe a Sustainable Development and Conservation Biology Program, University of Maryland, College Park, Maryland, USA b Centre for Riverine Landscapes, Faculty of Environmental Sciences, Griffith University, Australia c University of Central America, Managua, Nicaragua d Conservation Management Institute, College of Natural Resources, Virginia Tech, Blacksburg, Virginia, USA e Conservation Science Program, World Wildlife Fund, Washington, DC, USA ABSTRACT 1. The common name ‘tilapia’ refers to a group of tropical freshwater fish in the family Cichlidae (Oreochromis, Tilapia, and Sarotherodon spp.) that are indigenous to Africa and the southwestern Middle East. Since the 1930s, tilapias have been intentionally dispersed worldwide for the biological control of aquatic weeds and insects, as baitfish for certain capture fisheries, for aquaria, and as a food fish. They have most recently been promoted as an important source of protein that could provide food security for developing countries without the environmental problems associated with terrestrial agriculture. In addition, market demand for tilapia in developed countries such as the United States is growing rapidly. 2. Tilapias are well-suited to aquaculture because they are highly prolific and tolerant to a range of environmental conditions. They have come to be known as the ‘aquatic chicken’ because of their potential as an affordable, high-yield source of protein that can be easily raised in a range of environments } from subsistence or ‘backyard’ units to intensive fish hatcheries.

  • Lagoon Tilapia: Bioprofile and Prospects for Coastal Fisheries Development
    LAGOON TILAPIA: BIOPROFILE AND PROSPECTS FOR COASTAL FISHERIES DEVELOPMENT John Blay (Ph.D.) DEPARTMENT OF FISHERIES AND AQUATIC SCIENCES An Inaugural Lecture Delivered at the University of Cape Coast on Thursday May14, 2009 ABSTRACT Lagoon tilapia Sarotherodon melanotheron also known as the black-chinned tilapia or the black-cheeked tilapia is a common fish in lagoons in Ghana, constituting over 90% of the ichthyomass in these habitats. Unfortunately its potential in the coastal fishery production has largely been overlooked although it supports important local subsistence and commercial fisheries. This lecture presents a review of the biology of populations of the species in Ghana highlighting my contributions in this regard. It will show how characteristics as tolerance range of brackish conditions, food habits, growth, reproductive habits, and ability to survive under harsh environmental conditions influence the production of natural populations. Recommendations are made for managing the natural lagoon and reservoir stocks, and aquaculture of the species. 1.0 INTRODUCTION I am greatly honored for the opportunity to share with you aspects of my academic career in my field of specialization that is Zoology, particularly in the area of fisheries biology. Although this academic requirement has delayed three years, it is unique for me as I happen to be the first Professor in Ghana to have a female Vice Chancellor presiding over his Inaugural Lecture. Furthermore it is the first inaugural lecture coming out of the Department of Fisheries and Aquatic Sciences, and the School of Biological Sciences, and the fourth in Zoology. As my lecture deals with an issue in the aquatic sciences, it is imperative that I acknowledge the presentations by my predecessors because what they spoke about largely influenced my choice of today’s topic.

(2018): “Status: Established or possibly established in ten states. Established in parts of Arizona, California, Florida, Nevada, North Carolina, and Texas. Possibly established in Colorado, Idaho, Oklahoma, and Pennsylvania. Reported from Alabama, Georgia, and Kansas. For more than a decade it has been considered the most widespread foreign fish in Florida (Hale et al. 1995).” “Nonindigenous Occurrences: This species (often identified as Tilapia nilotica) was stocked annually by the Alabama Department of Conservation and Auburn University in lakes and farm ponds in Alabama during the late 1950s, 1960s, and 1970s (Rogers 1961; Smith-Vaniz 1968; Habel 1975). There are a few records of populations surviving mild winters, such as an account for Crenshaw County Public Lake, a southern Alabama public fishing lake, between 1971 and 1972 (Habel 1975). One recent record is of 25 specimens taken from Saugahatchee Creek in the Tallapoosa drainage, Mobile Basin, near Loachapoka, Lee County, on 2 October 1980 (museum specimens).

  • Tilapia Feed Management Practices in Sub-Saharan Africa
    377 Tilapia feed management practices in sub-Saharan Africa Abdel-Fattah M. El-Sayed Oceanography Department Alexandria University Alexandria, Egypt El-Sayed, A.-F.M. 2013. Tilapia feed management practices in sub-Saharan Africa. In M.R. Hasan and M.B. New, eds. On-farm feeding and feed management in aquaculture. FAO Fisheries and Aquaculture Technical Paper No. 583. Rome, FAO. pp. 377–405. ABSTRACT Tilapia is a traditional source of nutrition for the general population in many countries in sub-Saharan Africa (SSA). However, farmed tilapia production in SSA is relatively low, representing only about 2.5 percent of global tilapia production in 2010. At the continental level, the Arab Republic of Egypt was the largest contributor to African tilapia culture (86.3 percent) in 2010, while SSA contributed only 13.7 percent. This review considers only those SSA countries whose tilapia production exceeds 500 tonnes per year: the Republic of Côte d’Ivoire, the Democratic Republic of Congo, the Republic of Ghana, the Republic of Kenya, the Republic of Malawi, the Federal Republic of Nigeria, the Republic of the Sudan, the Republic of Uganda, the Republic of Zambia and the Republic of Zimbabwe. Tilapia culture in SSA has recently been growing at an outstanding rate, increasing during the period 2006 to 2010 from 39 883 tonnes to 88 238 tonnes/year. Tilapia culture in SSA is mainly a small-scale, semi-intensive activity, practiced mainly by non-commercial farmers in freshwater earthen ponds. Medium and large-scale, intensive cage culture is also practiced in a few countries (e.g.

We discuss geographical distribution and phylogeny of Dactylogyridea (Monogenea) parasitizing Cichlidae to elucidate their hosts’ history. Although mesoparasitic Monogenea (Enterogyrus spp.) show typical vicariant distribution, ectoparasitic representatives from different continents are not considered sister taxa, hence their distribution cannot result from vicariance alone.
