Pond types included traditional levee ponds, split- ponds, water. Ponds were located in major catfish producing areas of west Alabama, east Arkansas, and Mississippi. Water samples were collected from 20 catfish ponds in 2015 to obtain data useful in predicting copper toxicity and chemical behavior. In either production system, hybrids.Ī survey of catfish pond water chemistry parameters for copper toxicity modelling Due to that, and their faster growth, hybrids are typically produced in “single-batch” production systems, either in intensively-aerated commercial ponds or in split- pond systems. Hybrid catfish are more efficiently harvested by seining than are Channel Catfish. Ponds (0.04 ha) w.Ĭannibalism in single-batch hybrid catfish production ponds furcatus) reared in nursery ponds and then stocked were compared between fish fed immediately after stocking (standard industry practice) and fish forwhich feedingwas postponed after stocking. Production variables of hybrid catfish (Channel Catfish Ictalurus punctatusÃ-Blue Catfish I. Postponed feeding does not substantially reduce production expense during pond rearing of hybrid catfish fry Under certain conditions, organic fertilizers may be beneficial to provide forage for z. This paper reviews the assumed advantages and disadvantages of organic fertilizers and presents the case that the risks outweigh the benefits for channel catfish, Ictalurus punctatus, nursery pond fertilization. The Case Against Using Organic Fertilizers in Channel Catfish Ictalurus punctatus Nursery Ponds

Many fish culturists are interested in applying copper sulfate pentahydrate (CSP) to channel catfish, Ictalurus punctatus, nursery ponds as a prophylactic treatment for trematode infection and proliferative gill disease by killing snails and Dero sp., respectively, before stocking fry.
