Freshwater aquaculture is an important source of greenhouse gas (GHG) emissions. GHG emissions are expected to lead global warming and climate change. A reduction in urgently required for the sustainable development freshwater aquaculture. In this study, a laboratory-scale experiment was conducted analyze effects vegetable–fish co-culture on CH4 N2O from pond. The results show that co-culturing...
Abstract The North American channel catfish Ictalurus punctatus has been introduced to several locations in Europe but received little or no scientific study despite its invasive attributes, including prolific reproduction, tolerance a wide range of conditions, opportunistic feeding, at least partial ‘predator release’, and some evidence environmental impacts (e.g. disease transmission). To ass...
Edwardsiella ictaluri is a Gram-negative facultative intracellular pathogen causing enteric septicemia of channel catfish (ESC). The disease causes considerable economic losses in the commercial catfish industry in the United States. Although antibiotics are used as feed additive, vaccination is a better alternative for prevention of the disease. Here we report the development and characterizat...
— American White Pelicans ( Pelecanus erythrorhynchos ) are reported to consume large quantities of commercial catfish in Alabama, Arkansas, Louisiana and Mississippi, negatively impacting aquaculture production. If pelicans consume a single item diet, such as catfish, nutritional deficiencies may result. Therefore, effects of monoand multi-species diets were examined to determine nutritional i...
Two experiments were conducted in 200-m earthen ponds at Asian Institute of Technology, Thailand, for 87 days to test the feasibility of an integrated pen-cum-pond system, which utilizes wastes from intensive culture of hybrid catfish (Clarias macrocephalus C. gariepinus) as nutrients for semi-intensive culture of Nile tilapia (Oreochromis niloticus). This integrated pen-cum-pond system enhance...
PETRINEC, Z., S. NEJEDLI, S. KUŽIR, A. OPAČAK: Mucosubstances of the digestive tract mucosa in northern pike (Esox lucius L.) and european catfish (Silurus glanis L.). Vet. arhiv 75, 317-327, 2005. ABSTRACT The distribution and quality of mucosubstances in the digestive tract of pike (Esox lucius) and catfish (Silurus glanis) is described. The digestive tract of pike and catfish is short, in ac...
Catfish represent 12% of teleost or 6.3% of all vertebrate species, and are of enormous economic value. Here we report a high-quality reference genome sequence of channel catfish (Ictalurus punctatus), the major aquaculture species in the US. The reference genome sequence was validated by genetic mapping of 54,000 SNPs, and annotated with 26,661 predicted protein-coding genes. Through comparati...
, 5000 six-page surveys (Appendix 1) were sent to a stratified-random sample of Nebraska anglers drawn from the 2001 Licensed Anglers database. The database included all anglers who purchased a license in 2001 as well as all lifetime fishing permit holders who purchased their license before or during 2001. The database did not include those possessing a free permit, such as veteran's or senior ...
The carbamate pesticide, aldicarb, demonstrates significant acute toxicity in mammals, birds, and fish through the inhibition of acetylcholinesterase (AChE), and may present high potential for exposure of aquatic organisms during periods of runoff. Toxicity studies have shown that channel catfish are less sensitive to the acute toxic effects of aldicarb than are rainbow trout or bluegill. An ea...
The Vietnamese fisheries sector, including both marine and aquaculture, has made spectacular progress in recent years, becoming one of the top seafood producing exporting countries world. Looking forward, development goals this sector must address challenges associated with climate change, changing distribution commercially important species such as tuna disruptions to land-based aquaculture pr...
