This book was released on 1970 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The experiment was conducted at the Soap Creek farm ponds near Corvallis, Oregon. Oregon Moist Pellet and Purina Trout Chow at three different rates of feeding for each diet were used to feed fingerling channel catfish stocked at the rate of 1,000 per acre. A complete random design and Fisher's least significant differences tests of the means were employed to compare the growths of fish from six treatments which were sampled at three separate times. The growth rates of fish from all treatments were quite similar and the differences of the mean length and weight of fish from each period of rearing were not consistent, which suggests that their growth rate was not dependent upon the diets or the feeding rate but rather upon some factor such as temperature. The standard deviations of the mean weights of fish were extremely high, which indicates that not all fish relied on the supplemental foods. Positive values of the amount of skewness in the weight frequency distributions indicates that the majority of fish were small. The mean conversion factors for both diets at any feeding level were quite similar, which suggests that the fish did not respond well to an increase in the amount of food available. And since the fish in this experiment did not rely completely on the artificial diets, the conversion factors are of little value from a nutritional standpoint. The production of fish in this experiment was in the neighborhood of 66 kg. per surface acre over a period of 151 days. This figures indicates that rearing channel catfish with supplementary feeding in the Willamette Valley might hold promise.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Symptoms were identified in channel catfish fed diets deficient in the water-soluble vitamins pyridoxine, pantothenic acid. riboflavin, thiamine, folic acid, nicotinic acid, B-12, or Choline. Fat-soluble vitamin A and vitamin K deficiency systems were observed after feeding diets which contained beta-carotene and 4.0 milligrams of menadione (synthetic vitamin K) per 100 grams of food (dry weight). These deficiencies were eliminated by substituting vitamin A palmitate for beta-carotene and doubling the content of menadione. No dietary need was observed for the water-soluble vitamins biotin, inositol, ascorbic acid, and para-aminobenzoic acid.

Download or read book Biology and Culture of Channel Catfish written by C.S. Tucker and published by Elsevier. This book was released on 2004-09-30 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of channel catfish farming in the United States serves as a model for the development of pond-based aquaculture industries worldwide. Channel catfish farming is the largest and economically most important aquaculture industry in the United States. In 2003, over 300,000 metric tons (662 million pounds) of channel catfish were processed, representing about half the total United States aquaculture production. Demand for farm-raised catfish is strong, with record processing years in 2002 and 2003. In 22 chapters written by active scientists in the field, Biology and Culture of Channel Catfish comprehensively synthesizes over 30 years of research on this American icon. Throughout the book, fundamental biological aspects of channel catfish are linked to practical culture techniques. Topics include: • Latest information on reproductive physiology, genetics, and breeding • Comprehensive treatment of catfish nutrition, feeds, and feeding practices • Water quality management and pond dynamics • In-depth review of immunology in channel catfish • Practical information on diseases and health management • Techniques for commercial culture, including innovative techniques such as raceways, recirculating systems, and partitioned aquaculture systems • Catfish economics and marketing • Exploration of environmental concerns, including recommended Best Management Practices

Available in PDF, EPUB and Kindle. Book excerpt: In 2000, the Iowa Department of Natural Resources began using 10 0.4-ha and six 0.04-ha plastic-lined ponds at the Rathbun Fish Hatchery and Research Facility (Moravia, Iowa) to culture game fish that are subsequently stocked into public waters. During the first 3 years of use, inconsistent growth and survival of channel catfish (Ictalurus punctatus) were evident. Two separate studies were composed to better understand the culture of channel catfish in these ponds. The effects of stocking density was investigated in the 0.4-ha production ponds. In 2003, stocking densities were 75,000 and 112,000 fish/ha. No significant differences were seen in catfish production; although fish in the lower treatment were slightly larger. The only significant difference with regard to water quality was that the ponds stocked with 112,000 fish/ha had higher concentrations of total phosphorus. In 2004, the same ponds were stocked at rates of 38,000 and 75,000 fish/ha. The fish in the lower treatment exhibited significantly higher specific growth and normalized biomass. These fish were also significantly longer and heavier at harvest. Ponds stocked at a rate of 75,000 fish/ha had significantly higher concentrations of on ammonia, total phosphorus and chlorophyll a. In 2004, the six 0.04-ha plastic-lined ponds were used in conjunction with six 0.08-ha earthen ponds located at the Iowa State University Horticulture Station (Ames, Iowa), to assess the effects of dietary protein percent on the production of channel catfish. Plastic-lined ponds that received the 28% protein feed exhibited significantly higher levels of total phosphorus and turbidity. Earthen ponds that received the 36% protein feed displayed significantly higher concentrations of ammonia and chlorophyll a. Fish fed the 36% protein diet in the plastic-lined ponds had significantly higher relative weights (W[Subscript r]) then fish fed the 28% protein diet. There was a significant difference in harvest lengths and weights in the earthen, with the fish fed the 36% protein feed being longer. A stocking density between 38,000 and 75,000 fish/ha should be used to culture channel catfish fingerlings in plastic-lined ponds in Iowa, with fish being fed a feed that contains over 28% protein.
