Fortunately, all the above datum also tell that there are big profits for Nigerian fishery, fish farmers, fish feed manufacturers and suppliers if they can use scientific methods to develop aquaculture, adjusting measures to local conditions and importing the reasonable-priced fish feed machines with good quality to...
The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a peak of metals appears. For some years, the focus of attention on metal toxicity and the explanation of mortalities was...
Pond Deicing Can Help Prevent Fish Kill
Keeping the pond open will help keep oxygen in the water, attract water fowl and help prevent fish kills in the spring.
The most common cause of fish kills is suffocation due to lack of dissolved oxygen. Most dissolved oxygen is produced by algae and aquatic plants through photosynthesis. A lesser but also important source of oxygen in water is diffusion from the atmosphere, which is enhanced by wind-induced surface water turbulence. (Sallenave NMSU.edu)

PRF has been in the prawn business since 1994 and was granted approval in 2016 to expand their farm by 259 hectares. PRF depended on consistent, low maintenance aeration to ensure the healthy growth of...
Inland fish play critical roles in North American ecosystems and economics: In the U.S. alone in 2011, freshwater anglers spent more than $30 billion on their hobby, generating $73 billion in economic output. And fish help keep nature in balance as they feed on aquatic plants and animals and in turn provide sustenance to iconic species such as eagles, bears and osprey.
It’s no surprise, then, that as climate changes, 30 experts gathered last year in Bozeman, Montana, to explore implications for the well-bein...
