Abstract:

The big-oui hybrid catfish (female C. macrocephalus x male C. gariepinus) was successfully achieved using artificial hybridization. This hybrid combines the superior taste of the C. macrocephalus with the faster growth rate and higher resistance to environmental conditions of the C. gariepinus and is now the biggest fresh-water aquaculture product in Thailand. In this thesis the results of experiments involving hybridization and genetic manipulation were used to investigate the nature of the hybridization event. This information was used to develop broodstock for Clarias catfish breeding progr

Abstract:

Chiloglanis pretoriae is a rock catlet, indigenous to southern Africa. The aim of the study was to develop a technique to culture C. pretoriae as an alternative to harvesting and selling wild caught fish on the international aquarium trade. As nothing was known about the culture of African rock catlets an investigation into the biology and ecology of the species was necessary to develop the culture protocol. Chiloglanis pretoriae inhabits fast flowing rapids (current speeds over 0.6 metres per second). It is a serial interstitial gravel spawner, that spawns during the summer months. Chiloglani

Fermented silage was prepared from a mixture of minced tiiapias (Oreochromis spp. ), different carbohydrate substrates (molasses, corn flour, tapioca flour) and Lactobacillus plantarum as inoculum, incubated anaerobically for 30 days at 5°-35°C. The pH and protein solubilization were temperature-dependent, and the source of carbohydrate substrate did not affect non-protein nitrogen (NPN) content or proximate composition of tilapla silage. During storage at 30°C for 180 days, NPN content increased and there was 8-11% loss of tryptophan. Moist diets containing tilapla silage (stored up to 60 day

Abstract:

In Southeast Asia, the family Pangasiidae is important for commercial fisheries and aquaculture. Pangasianodon hypophthalmus (striped catfish) is the most economically important species farmed in Vietnam, with a total export value of 1.7 billion USD in 2012. Intensive aquaculture can lead to problems with major outbreaks of disease and Edwardsiella ictaluri and Aeromonas hydrophila represent two important bacterial pathogens in P. hypophthalmus aquaculture. Immunostimulants have proven to be a very useful food additive for the aquaculture industry, since they can be easily fed to fish to enhan

Electrofishing captured twice as many channel as flathead catfish, and hoop nets captured twice as many flatheads as channel catfish. Growth rates of channel catfish were fast as compared to documented growth in other rivers in the United States, with ages ranging from 1-8. Flathead catfish growth was average whe

Inadequate seed production has historically been a factor limiting the commercial culture of Clarias gariepinus.

The effects of key environmental factors on the growth, survival and aspects of the behaviour of C. gariepinus larvae and juveniles were investigated under controlled conditions. A strong emphasis was placed on the interpretation of the observed responses in terms of the natural history of the animal. Larvae were obtained by artificially

Abstract:

The blue catfish, Ictalurus furcatus, is an invasive species introduced to Virginia in 1974 and is the largest catfish in the United States. Like other Ictalurids, they are capable of producing disturbance calls via stridulation of the pectoral spine. These sounds can be made in air and water, and catfish can be preyed upon by both aerial and underwater predators. I characterized these putative distress calls by recording them in air and in the fish’s natural habitat. Sounds exhibited a wide variation in acoustic parameters relative to fish ontogeny: larger fish produced higher amplitude sound

Abstract:

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>In aquaculture, eugenol have been used and recommended as anesthetics for several fish species. Moreover, this product has attracted the attention of researchers because of its chemopreventive, anti-inflammatory and antioxidant properties, as well as, its antimicrobial potential. The aim of this study was to evaluate the activity of eugenol against the fish pathogen Aeromonas hydrophila and eugenol s effect on hematological and natural immune parameters in silver catfish (Rhamdia quelen). In vitro, eugenol showed weak activity agai

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>The aim of this study was to evaluate the effect of the essential oil of Lippia alba (EOLA) as a feed additive on ionoregulatory and metabolic parameters, and pituitary hormones expression in silver catfish, Rhamdia quelen. Fish were fed for 20 days with different concentrations of EOLA (0.0 control, 0.25 and 0.50 mL kg-1 food). Plasma Na+, Cl- , K+ and cortisol, and metabolic parameters were not affected by the diet, with the exception of ALT (alanine aminotransferase), which was higher in the liver of fish fed 0.50 mL EOLA kg-1
