Aquaculture & Fisheries Articles
Non Nutritive Feed Additives
Feed formulation is essentially applied nutrition. A number of terms and expressions are introduced that will be put to practical use as information is presented on the nature and qualities of various feedstuffs and the information presented on the nutrient requirements of fish. Precise understanding of these terms is essential to their correct application. One must recognize that some of these terms have a built-in error that cannot be escaped. Read the full

Photoperiodism In Fishes
For most animals the seasonally changing pattern of day length provides
the most accurate year-on-year index of time and many fish use the
increasing and decreasing components of this light cycle to coordinate
development. In order to use light in this way, however, firstly the
light must be perceived, secondly, day length change must in some way
be measured and lastly, this information must be transduced into a
suitable 'message' for integration by the newoendocrine cascade
which initiates and then modulates development. Photoperiod is the
ability of organisms to and use the body length as an anticipatory
cue to time seasonal events in their life histories. Read the full

Biological water treatment in aquaculture by means of "Mutag BioChip™ RAS Process"
Aquaculture or fish farming means the artificial breeding and raising of aquatic creatures. They include fish as well as
crustaceans and shellfish, which are raised and stocked under controlled conditions by using techniques and
technologies offering an increased level of productivity which cannot be realized under natural conditions. Due to the
increased demand for freshly caught fish and considering the imminent overfishing of the oceans, aquacultures attach
growing importance while there are different types of aquaculture installations. Read the full

Non Viral Gene Delivery Approaches In Fish
Gene delivery using nonviral approaches has been extensively studied as a
basic tool for intracellular gene transfer and gene therapy. Since
its development, gene therapy has held great promise in the field of
medicine. The ability to introduce functional genes into mammalian
cells containing otherwise defective copies offers many new
possibilities for the treatment of commonly acquired and inherited
fish diseases such as autoimmune disorders and monogenic diseases.
The development of efficient gene therapy depends on an efficient
transfer of therapeutic genes into a cell to replace or silence
defective ones associated with fish disease. Read the full

Seaweed Mariculture: Scope and Potential
Marine algae, commonly known as seaweeds are one of the major
potential living as well renewable resources of the oceans. Seaweed
resources available around the world include more than 1000 species,
from which only a hundred species are being commercially used.
Seaweeds are mainly utilized in phycocolloid industries, but many
edible types of seaweed are rich in proteins, vitamins, minerals and
trace metals. In the past few decades, the research in the marine
areas has yielded vast knowledge on seaweed utilization. Read the full

HOW TO SECURE YOUR PREPAYMENT
When you need to make an advance payment to a new supplier, it is always sensible to secure the return of the money in case the goods are not shipped. Read the full
