Water Quality Concerns for Ponds - Penn State Extension

2015-8-27 · Fish kills due to low oxygen are most common during hot, dry spells when algae grow and then die quickly. The organisms that decompose the dead algae may use so much oxygen that what remains is insufficient for fish. In very deep ponds, the deepest portions of the pond may have very low dissolved oxygen concentrations due to poor aeration.

In former process hot and dry gas, usually air, is used both to supply the heat necessary for evaporation and to remove the water vapor from the surface of the food, whereas, in latter process the moist food is brought into contact with a hot surface (or, in a particular appliion, with superheated steam) and the water in the food is boiled-off.

Fish Processing - an overview | ScienceDirect Topics

Fish processing generates valuable by-products that are high in proteins and lipids, such as viscera, skin, tails, heads, and frames. The disposal of these nutrient-rich byproducts can often increase costs. By using enzymes to valorize byproducts, processors can potentially obtain additional revenue from nutritional supplements, ingredients for pet food, biodiesels, fertilizers, agricultural

Food processing and nutrition - Better Health Channel

Almost all food is processed in some way before it is eaten. Commercially, the main reasons to process food are to eliminate micro-organisms (which may cause disease) and to extend shelf life. Simply cooking or coining a food with other foodstuffs to create a recipe is also considered a form of food processing. Whatever the case, the nutrient
