Available in PDF, EPUB and Kindle. Book excerpt: Culture of Nonsalmonid Freshwater Fishes, 2nd Edition presents an expanded, updated description of important techniques and practices for the culture of some of the most widely cultured nonsalmonid species used for human consumption (channel catfish, tilapia, carp) for stocking freshwater bodies for recreational fishing (bass, walleye, striped bass), and for bait (minnows). This new edition features the latest information on spawning, nutritional requirements, special culture requirements, tolerance to various water quality parameters, and types of diseases that can occur. It is an essential book for all aquaculturalists, agency fishery biologists, and students interested in freshwater aquaculture.

Available in PDF, EPUB and Kindle. Book excerpt: A state-of-the-art assessment of research, demonstration, and commercial projects that involve the use of power plant condenser cooling water for agricultural and aquacultural purposes was conducted. Information was obtained from published literature, site visits, and communications with knowledgeable individuals. Thermal effluent uses were discussed for controlled environment greenhouses, biological recycling of nutrients from livestock manures, soil heating and irrigation, environmental control for livestock housing, grain drying, food processing, as well as the culture of numerous aquatic organisms. A large number of research and feasibility studies have been conducted, but few commercial enterprises are utilizing thermal effluent. Interfacing problems, environmental and legal restrictions, along with insufficient technology, have not allowed widespread commercial application. Specific research needs were discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Provides the basic concepts and techniques required to rear warmwater animals in both fresh and marine environments and under controlled or semi-controlled conditions. Utilizes examples from various species to demonstrate how specific general principles can be applied throughout the field. Focuses on commercially important species that are being or can be reared in the United States. The concepts can also be applied to animals reared for laboratory use. Includes a comprehensive bibliography to the literature.
Download or read book Rearing of Channel Catfish Ictalurus Punctatus Rafinesque and Brown Bullheads I Nebulosus Lesuer in Floating Cages in a Pond Near Corvallis Oregon written by James Robert Nielsen and published by . This book was released on 1972 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study designed to evaluate the use of floating cages for rearing fingerling and subadult channel catfish (Ictalurus punctatus) and fingerling brown bullheads (I. nebulosus) on a commercial basis in Oregon's Willamette Valley was conducted at a pond seven miles north of Corvallis, Oregon, from May 23 to October 17, 1970. Fish were stocked in 1.4 m3 floating cages at the rate of 150 fish/cage (110 fish/m3) and fed either a dry, floating feed (Purina Trout Chow) or a moist, sinking feed (Oregon Moist Pellet). Channel catfish were fed 3.0% of body weight/day. Brown bullheads were fed either 3.0 or 4.5% of body weight/day. Water temperature in the experimental pond was above 21 C for approximately 90 days in 1970. A season of 160-210 days of water temperatures over 21 C is usually required to grow catfish from fingerlings to a commercially-usable size of 340-570 g in one season. The fingerling channel catfish had an average weight of 96.4 g and an average fork. length of 195.3 mm at the termination of the experiment. Yield at the end of the experiment averaged 11.8 kg/cage and food conversion ratios averaged 1.9:1. There were no differences among the cages of fingerlings in yield, conversion ratio, or average weight and fork length. There were more small fish in cages where the fingerlings were fed the sinking diet than in the cages where the floating diet was fed. This was probably due to the restricted feeding area required for the sinking diet (a metal tray with a surface area of 0.4 m2), which caused more competition among the fish fed the sinking diet than probably occurred among the fish fed the floating diet. Losses among the fingerling channel catfish averaged 17% of the fish in each cage. Handling was considered to be the chief factor of mortality. Twenty percent of the subadult channel catfish were grown to a commercially-usable size (340 g or more) by the end of their second growing season in Oregon. Yields for the subadults were 31.4 kg for the fish fed the sinking diet and 35.8 kg for the fish fed the floating diet. Conversion ratios were 1.5:1 for the floating diet and 1.8:l for the sinking diet. Losses averaged 4% of the fish in each cage, all of which were attributed to poisoning from tarichatoxin exuded from the skin of the rough-skinned newt (Taricha granulosa granulosa) that was common in the pond. Apparently, the catfish were poisoned when they attacked the newts and bit them. Ninety-five percent of the brown bullhead fingerlings died as a result of severe columnariasis outbreaks in May and June, following handling. Growth data obtained from brown bullheads collected from lakes and reservoirs in central and western Oregon showed that growth under natural conditions in these areas may be sufficient to enable this species of catfish to be used in low-intensity cultural operations. Yields resulting from the use of floating cages for rearing fingerling channel catfish were greater than those observed in previous experiments at the same ponds in which fingerling channel catfish were raised free in the ponds, both with and without artificial feeding. High-intensity culture of channel catfish in ponds in Oregon's Willamette Valley does not appear to be economically feasible. The factor limiting the growth of catfish in this area appears to be low water temperatures.
