Available in PDF, EPUB and Kindle. Book excerpt: Seventy-two pairs of channel catfish Ictalurus punctatus were induced to spawn in glass aquaria by injecting fish pituitary into the females. Control of peritoneal lesions, infections, and adhesions, was anticipated by including 10,000 unites of crystalline penicillin-G with each injection. Spawning was induced by injecting acetone-dried pituitaries from carp, buffalofish, flathead and channel catfish, and gar. Pituitaries from these various species differed little, regardless of time of collection. The amount of pituitary material required to induce spawning varied from 3 to 32 milligrams per pound of fish weight, given in from 1 to 28 injections, with an average of 3. Most females required 3 injections at 2 milligrams per pound of body weight every 24 hours. The period of time from the last injection to spawning varied from 2 1/2 hours to 72 hours, but averaged 16 to 24 hours.

This book was released on 2018-02-05 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Spawning Behavior of the Channel Catfish Ictalurus Punctatus Fish for spawning were selected during the breeding season, from the middle of April to the last week in July when water temperatures ranged from 70 to 85 F According to oral reports from the Federal fish-culturists of the southwestern United States, the largest or old est fish spawn first, while the smallest fish are usually the last to spawn. Each selected female was placed with a male in an aquarium The condition of the females for spawning was rated excellent, al though it was always difficult to evaluate the exact physiological condition. Each female was well-rounded, and the roundness of the abdomen extended past the pelvics tothe genital orifice. The belly was flaccid, and the genitals were raised and reddish. The females ranged from l4'to 17 inches in length. They received pituitary injections to induce spawning.

Available in PDF, EPUB and Kindle. Book excerpt: Although catfish have been farmed for about 30 years and catfish farm ing is the most successful aquacultural enterprise in the United States, there are those who contend that catfish farming is still as much of an "art" as it is a science. This position is difficult to refute completely, particularly considering that some practices used in catfish farming ap pear to have little scientific basis. Skill coupled with a small dose of mysticism certainly playa role in the culture of catfish, and the catfish producer is faced with the unenviable task of rearing an animal in an environment that requires considerable management. Certain aspects may still be an "art" because research and technical information needed to support the industry have lagged behind industry growth; however, the basic principles underlying catfish farming are based on sound scientific evidence whose foundation was laid in the 1950s by work conducted at state and federal fish hatcheries in the southeastern and midwestern United States. Since that time, several university and government laboratories have expanded the scientific base for catfish farming. As a result, considerable information is available, but it is gen erally fragmented and exists in a multitude of diverse scientific and trade journals. The material is often too technical or abstract to be com prehensible to fish culturists and personnel in allied industries. This book fits the definition of the term handbook in the sense that it is intended as a book of instruction or guidance as well as a reference.

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
