Estimating Daily Growth Of Age-0 Channel Catfish In A Free-Flowing, Commercially Exploited Midwestern River, Kaleb B. Wood
Estimating Daily Growth Of Age-0 Channel Catfish In A Free-Flowing, Commercially Exploited Midwestern River, Kaleb B. Wood
Masters Theses
The larval stage in fishes is an important stage in the life history, as their survival dictates the ability of the population to sustain itself as an adult population. While there is a plethora of information available for juvenile and adult life stages of Channel Catfish (Ictalurus punctatus), very little is understood about their larval life stage. This study sought to determine overall density, growth rates, and size structure of cohorts of age-0 Channel Catfish during a study year on the Wabash River. In 2018, I sampled age-0 Channel Catfish using a benthic trawl from May to September. …
Effects Of Microcystin-Lr On Channel Catfish (Ictalurus Punctatus) Susceptibility To Microbial Pathogens (Aeromonas Hydrophila And Edwardsiella Piscicida), Alison Marchant
Theses and Dissertations
Microcystin-LR is a hepatotoxin produced by cyanobacteria. Aeromonas hydrophila and Edwardsiella piscicida infections are leading causes of losses in market-sized channel catfish (Ictalurus punctatus). These older fish should have natural immunity in place and a predisposing factor is likely a prerequisite for these disease outbreaks. While microcystin-LR rarely causes mortality in warm-water aquaculture, we believe it may be a predisposing factor that leads to bacterial disease outbreaks during the summer months due to its ability to damage the liver. Our study investigated microcystin-LR’s effects on channel catfish susceptibility to these pathogens. We found that a sublethal dose of microcystin-LR induced …
Comparison Of Unused Water And Year-Old Used Water For Production Of Channel Catfish In The Biofloc Technology System, Bartholomew W. Green, Kevin K. Schrader, Steven D. Rawles, Carl D. Webster, Matthew E. Mcentire
Comparison Of Unused Water And Year-Old Used Water For Production Of Channel Catfish In The Biofloc Technology System, Bartholomew W. Green, Kevin K. Schrader, Steven D. Rawles, Carl D. Webster, Matthew E. Mcentire
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Since excreted feed nitrogen is bio-transformed efficiently in a fully functional mixotrophic biofloc technology production system, re-using this biofloc water over multiple production cycles should be beneficial. The present study, conducted in an outdoor biofloc technology production system, evaluated impacts on fish production characteristics and mineral status, common microbial off-flavors, and water quality dynamics for channel catfish (Ictalurus punctatus) reared in one-year-old waters with low or high total suspended solids used previously for two consecutive catfish biofloc studies or in unused (new) water. Total suspended solids were maintained at 300 to 400 mg/L in the unused and low …
Effects Of Solids Removal On Water Quality And Channel Catfish Production In A Biofloc Technology Production System, Bartholomew W. Green, Kevin K. Schrader, Matthew Mcentire
Effects Of Solids Removal On Water Quality And Channel Catfish Production In A Biofloc Technology Production System, Bartholomew W. Green, Kevin K. Schrader, Matthew Mcentire
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Total suspended solids control was evaluated in a channel catfish (Ictalurus punctatus) biofloc technology production system. Settling chamber flow rates were 0.9 (LO) or 2.9 (HI) L/min to reduce total suspended solids to 300 mg/L; solids were not removed from control tanks. Channel catfish yields (7.6–8.7 kg/m3) were not affected significantly, but control fish were skewed toward smaller size classes. Control treatment channel catfish tolerated 1,410 mg/L total suspended solids without adverse effects. LO- and HI-treatment fillet geosmin concentrations were high enough to be designated as off-flavor. Water quality results suggested that nitrification was affected by solids removal.
Comparative Water Quality And Channel Catfish Production In Earthen Ponds And A Biofloc Technology Production System, Bartholomew W. Green, Matthew E. Mcentire
Comparative Water Quality And Channel Catfish Production In Earthen Ponds And A Biofloc Technology Production System, Bartholomew W. Green, Matthew E. Mcentire
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
This 210-day study compared variation in water quality and fish growth for channel catfish (Ictalurus punctatus; 47 g/fish) stocked in earthen ponds (1.5 fish/m2, 14,820/ha) and in a biofloc technology (BFT) production system with high-density polyethylene-lined rectangular tanks (12.6 fish/m2, 126,000/ha). Feed input and culture environment affected water-quality dynamics. In ponds, phytoplankton uptake predominated and little nitrification occurred, whereas in the BFT system phytoplankton uptake and nitrification maintained low ammonia-nitrogen concentrations. Size classes of fish were skewed toward the larger market sizes in ponds and toward smaller market sizes in the BFT system. Mean …
Performance Of A Temperate-Zone Channel Catfish Biofloc Technology Production System During Winter, Bartholomew W. Green
Performance Of A Temperate-Zone Channel Catfish Biofloc Technology Production System During Winter, Bartholomew W. Green
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Channel catfish (Ictalurus punctatus) have been grown successfully in an outdoor biofloc technology production system. Outdoor biofloc production systems in the tropic sare operated year-round, whereas the channel catfish studies were conducted only during the growing season and biofloc production tanks were harvested and idled for the winter. If an outdoor biofloc production system is to be adopted by farmers at temperate latitudes, then data gaps related to system and fish performance over the winter must be addressed. The present study was conducted to address these data gaps for channel catfish culture. Waters from a recently completed biofloc …
Exploitation Of Channel Catfish In Nebraska Flood-Control Reservoirs, Christopher Lee Wiley
Exploitation Of Channel Catfish In Nebraska Flood-Control Reservoirs, Christopher Lee Wiley
School of Natural Resources: Dissertations, Theses, and Student Research
Channel catfish Ictalurus punctatus, is a popular sportfish in North America, and is the third most-sought fish species in Nebraska. Exploitation rates of channel catfish populations have been estimated to be substantial in states neighboring Nebraska. Despite the popularity of channel catfish, little is known about the exploitation of channel catfish populations in Nebraska. The objectives of this study were to estimate the exploitation rates of channel catfish populations, identify the length bias of angling for channel catfish, and identify the self-imposed length limits for channel catfish at flood-control reservoirs of Nebraska. The software package Program Mark was used to …

Plankton community structure and chlorophyll a concentration were compared in 12 0.1-ha earthen ponds co-stocked with channel catfish (Ictalurus punctatus Rafinesque, 1818) in multiple-batch culture (initial biomass = 5,458 kg ha-1) and a planktivore, threadfin shad (Dorosoma petenense Güther, 1867; initial biomass = 449 kg ha-1), during the April-November growing season. We used a completely randomized design in 2 x 2 factorial arrangement to test planktivore level (presence or absence of threadfin shad) and channel catfish feeding frequency (daily or every 3rd d). Channel catfish were fed a 32% protein feed to apparent …

Effect Of Using Threadfin Shad As Forage For Channel Catfish Fed Daily Or Every Third Day, Bartholomew W. Green, Peter Perschbacher, Gerald Ludwig
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
We evaluated whether stocking threadfin shad Dorosoma petenense as a forage fish in multiple-batch production ponds for channel catfish Ictalurus punctatus could substitute for formulated feed when channel catfish were fed daily or every 3 d. A completely randomized design in a 232 factorial arrangement was used for the experiment, which was conducted in twelve 0.1-ha earthen ponds. Prespawn adult threadfin shad were stocked at 404 kg/ha in six of the ponds, whereas the remaining ponds received no threadfin shad. Channel catfish stockers (0.35 kg/fish) were stocked at 5,040 kg/ha, and fingerlings (28.2 g/fish) were stocked at 14,820 fish/ha. Channel …

Texture Profile Analysis And Composition Of A Minced Catfish Product, J. Lee Wiles, Bartholomew W. Green, R. Bryant
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Texture Profile Analysis of minced catfish products indicated that minced proteins from the belly flap meat have excellent functional properties to form gels or restructured products. Belly flap meat is considered a low-value trimming, with about 16.9% protein and 11.2% total lipid. Washing of minced catfish trimmings increased the moisture content from 71.5% to 77.9% while reducing mechanical hardness (19.1 N to 11.9 N), chewiness index (14.2 N to 8.83 N) and shear energy (0.82 J to 0.51 J). No significant changes were found in cohesiveness, resilience, and springiness of the minced fish after washing or the addition of 3.3% …

Comparison Of Three Methods Of Size Grading Channel Catfish Stockers, Bartholomew W. Green, David L. Heikes, Andrew E. Goodwin
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The stocking of size-graded catfish into production ponds should increase production efficiency, but grading large numbers of fish with existing technology is laborious. We evaluated the effectiveness of a mechanical grader recently developed at the University of Arkansas at Pine Bluff (UAPB) relative to that of box and sock graders and assessed injuries sustained by stocker channel catfish Ictalurus punctatus during grading. Three 0.25-acre ponds were stocked at 11,777 lb/acre. Initial total length (TL) ranged from 6.3 to 15.7 in, and initial weight of individuals ranged from 0.04 to 1.10 lb. The fish population in each pond was divided into …

Observations On The Life History Of Channel Catfish, Ictalurus Punctatus (Rafinesque) In Utah Lake, Utah, Robert E. Lawler
Observations On The Life History Of Channel Catfish, Ictalurus Punctatus (Rafinesque) In Utah Lake, Utah, Robert E. Lawler
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The channel catfish, Ictalurus punctatus (Rafinesque), was first introduced into Utah Lake in the summer of 1911, and has since been stocked in the lake on numerous occasions. It has only been in the last few years that the channel catfish has become an important game fish in Utah. As the value of the channel catfish, as a game fish, increased, it has become increasingly important to the state to maintain this species for present and future generations. This study was initiated in 1958 and completed in 1960, and was financed by the Utah State Department of Fish and Game. …
