Efficacy studies show that a wide variety of the bacterial pathogens that lead to mortality in warmwater fish are susceptible to florfenicol (Table 1), says Gaunt, associate professor of the fish lab at the university’s Department of Pathobiology and Population Medicine.
Wenger Manufacturing, Inc. recently introduced an aquatic feed extrusion system thatsurpasses the capabilities of other small diameter aquatic feed processes, and redefines allprevious shrimp feed production technology.
Intensive aquaculture can’t be conceived without a good aeration system. Maintaining dissolved oxygen at high levels enables us, among others things, to increase stocking densities, maintaining an optimal growth, and decreasing stress on fish, all of which generate a high resistance to diseases and also, better water quality.
Process Technology is pleased to announce the introduction of our SmartOne® line of PTC (positive temperature coefficient) electric immersion heaters. With this technology, thermal over-temperature protectors are no longer required to ensure safe operation. PTC aquaculture heaters are more dependable with extended service life and will not burn out in air like traditional resistance heaters. Unlike resistance heaters, these heaters continue working in high solids applications.
You will have your shrimps in 100 days!!! Have you heard of shrimps growing in about 100 days to the harvestable size of 30 counts? Yes, it is possible. Or fish fry, growing faster than normal? That too is possible.
At the same time protein fractionation (skimming) will lower the amount of bacteria and pathogens and increase the amount of oxygen. Traditional aquaculture filters, such as pressurized sand filters or cartridge filters remove particulates but do not remove protein waste and can actually increase the amount of bacteria and pathogens.
In the first installment of the RTI addition to this magazine, we introduced a number of products manufactured or distributed by Reed Mariculture, Inc. In this issue, we’ll show you just how easy it is to use these products.
With the constant evolution in feed regulation, the emergence of new environmental constraints and the global reduction of crucial raw materials such as fish meal, it is becoming more challenging to combine high productivity with sustainable practices. Many studies have already shown that the growth performance of feeds subjected to high replacement levels of fish meal are not adequate in terms of palatability and nutritional efficiency.
