Arrangement for a plankton net, for collecting plankton-containing water from arbitrary ocean depths.
Plankton Extract is an extract obtained from marine plankton
The inventive device is embodied as a mobile or fixed plankton video recorder for counting and identifying plankton in marine waters.
Oil obtained from cooked and pressed marine planktonic krill followed by centrifugation to remove water.
The device includes a casing, a plankton net and a collector.
An internal container (4) containing a stock of plancton has an outlet connected to the fish breeding basin with at least one supply line (13).
The feeding with this plankton remarkably enhances the survival rate of fry and larva as compared with the prior-art method.
The invention belongs to bioengineering, namely, to a method of processing chlorella planktonic strain suspension.
The present invention relates to an apparatus and a method for measuring the metabolic rate of motile organisms, such as sperm cells or some forms of plankton.
With regard to the monitoring of plankton, the samples are to be representative of the water column and to provide information on the presence of toxic species as well as on population trends.
Plankton and suspended substances, which are water contaminants, are preyed upon by fish or adsorbed by seaweed growing in a multi-void breaker.
As a result, plankton and floating contaminants in the water are eaten or adsorbed by fish, shellfish, and seaweed in the air gaps, thereby removing the contaminants from the water.
For this purpose a food portion in particular plancton is taken from a stock of deep-frozen food and defrozen and then fed with a water current into the fish breeding basin.
The mobility of the pen (30) provides the benefit of avoidance of localized hazards, like toxic plankton blooms, and the capability to move the pen (30) to a more convenient harvesting location, if necessary.
The present invention relates to methods for preventing and/or reducing biofilm formation and/or planktonic proliferation with one or more selected bacteria strains or bacterial blends.
The carp receives the above described supplementary feed in the ponds with a lower stocking density, where the half of the total increase of carp is formed by the natural food of plankton and benthos.
The darkness prevents algae, seaweed, and other types of sea life, such as plankton, from growing and developing by depriving them of the light needed for their existence.
The collector, which is used to collect the filtered plankton, is secured to the external surface of the lower fixed cover and comprises side windows for discharging the filtered water.
