Probiotics have been commonly practiced in commercial shrimp farms to increase pond production. However, these possibilities were based on the results of in vitro studies or laboratory in vivo trials. Here are the results of research that traced the composition and abundance of commercial probiotic species applied to commercial shrimp farms in an intensive aquaculture system using high-throughput sequencing. Probiotics...
by Amy Stone* As expenses increase and the markets get even more volatile, everyone is looking to cut costs. While there are many ways to reduce expenses, this article will focus on improving efficiency of existing pump systems. Variable frequency drives are a great tool for optimizing hydraulic systems. Variable frequency/speed drives, or VFDs/VSDs, are often coupled with water pumps...
By: Kalia Williams * Pond liners are used in ponds to keep water from seeping into the soil. They work by forming an impermeable layer between the water and the soil which prevents water loss. Pond liners also provide a base for plants to root themselves in, and provide a comfortable environment for fish to explore. Greenhouse coverings, although they...
Algae can be used as a replacement for fish oil and fishmeal, which aquaculture relies heavily on as a source of protein and fatty acids in formulated fish foods. In fact, microalgae are the primary producers of highly unsaturated fatty acids (HUFA) for the entire global food chain, marine and terrestrial segments combined. Because algae cultivation can make up 30-40%...
Based on a recently published study developed by an international research community from over 20 renown universities and institutions, this summarized article explores plausible aquaculture futures and their role in nutrition security using a qualitative scenario approach. Two dimensions of economic development – the degree of globalization and the predominant economic development philosophy – bound four scenarios representing systems that...
