Book Description
Bachelor Thesis from the year 2020 in the subject Biology - Miscellaneous, , language: English, abstract: Carp polyculture is the most common, popular, and successful aquaculture system in Nepal. Including mono-sex Nile tilapia in carp polyculture could enhance fish productivity. This present LEE work was conducted at the Fish hatchery complex of Fisheries Program, Agriculture and Forestry University, Rampur, Chitwan, in a cemented tank of area 25 m2 for 26 days to study the carp and mono-sex Nile tilapia in a polyculture system. The pond was fertilized using urea and DAP at the rate of 4,7 g/m2/week and 3.5 g/m2/week respectively. Fishes except Grass carp were fed twice daily with the pellet made from mustard oil cake and rice bran mixed at a 1:1 ratio at the rate of 5% BW. Grass carp were fed with duckweed at a rate of 50% BW twice a day from 7:30 am to 8 am and 1:30 pm to 2 pm. Water quality parameters i.e., water temperature, transparency, water depth, dissolved oxygen, and pH and were monitored daily while total alkalinity was monitored weekly. Sampling of fish was done fortnightly to check fish growth and adjust feed quantity. All the water quality parameters were within the optimal range of fish production except for DO which was very high during the afternoon. The extrapolated GFY and NFY were 14.5 t/ha/yr and 9.6 t/ha/yr, respectively. The overall survival of fish was 87% and AFCR was 1.4. The total variable cost and the production cost was NRs. 220/kg. Fishes were transferred to the Aquaculture farm, assuming the selling rate NRs. 300/kg. This makes the total gross return was of NRs. 875, making a total net profit of NRs. 327. The B: C ratio was 1.59. From this LEE work, it was concluded that carp and mono-sex Nile tilapia polyculture is a reliable and profitable venture to carry out.

Book Description
Intensive tilapia co-culture is the commercial production of various species of tilapia in conjunction with one or more other marketable species. Tilapia are attractive as a co-cultured fish because of their potential to improve water quality, especially in penaeid shrimp ponds, by consuming plankton and detritus and by altering pathogenic bacterial populations while increasing marketable production. Following introductory chapters covering ecological aspects of co-culture, tilapia feeding habits, historical use, and new models, Tilapia in Intensive Co-Culture is divided into co-culture in freshwater and marine environments. Co-culture core information is presented on Vibrio control, high-rate aquaculture processes, aquaponics, tilapia nutrient profile, and tilapia niche economics and marketing in the U.S, and with carp, catfish, freshwater and marine shrimp in the Americas, the Middle East, and Asia. Tilapia in Intensive Co-Culture is the latest book in the prestigious World Aquaculture Society (WAS) Series, published for WAS by Wiley Blackwell. It will be of great use and interest to researchers, producers, investors and policy makers considering tilapia co-culture in terms of environmental and economic sustainability.

Book Description
Ponds are a primary production system to a wide variety of freshwater fish species. Each species have specific and unique nutrient needs and successful pond fertilization is critical to a successful aquaculture enterprise. Aquaculture Pond Fertilization: Impacts of Nutrient Input on Production provides state-of-the-art information for successful fertilization strategies for a broad range of pond-raised species. Aquaculture Pond Fertilization attempts to rectify the seemingly contradictory nutrient recommendations by clearly defining the goals of specific types of aquaculture. Chapters are divided into three sections: The first reviews basic concepts in fertilization applicable to all pond-based production. The second looks at specific nutrient management approaches. The third and final section of chapters looks specifically at key freshwater pond species ranging from tilapia to perch and discusses specific fertilization needs for the successful rearing of these in-demand fish. Looking across species with chapters contributed by leaders in the field Aquaculture Pond Fertilization provides succinct single-volume coverage of an oft-neglected, but vitally important topic in aquaculture production.

Book Description
Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.

Book Description
Academic Paper from the year 2021 in the subject Agrarian Studies, grade: 3.84, , language: English, abstract: This paper is a retrospective review of Carp Polyculture in Nepal. Polyculture is an art and science of growing two or more compatible fish species in a pond to maximize production by taking advantage of different spatial distribution and feeding habits. Polyculture concepts rely on the complete utilization of various spatial niches and trophic of a pond to acquire a maximum production per unit area. Carp polyculture is the most common, popular, and successful aquaculture system in Nepal. Carp polyculture is the major aquaculture system contributing to more than 90% of total aquaculture production in Nepal. In 2018/19, total fish production, aquaculture, and productivity were 91,832 t, 70,832 t, and 4.92 t/ha, respectively, which is insufficient to fulfill the growing demand for fish in Nepal. Therefore, it is essential to increase production and productivity.

Book Description
This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.
