nio's ocean finder predictions to enhance fish catch | visakhapatnam news - times of india - transparent plastic sheet
VISAKHAPATNAM: In the past, fishermen used to go to sea by boat, and the days of throwing nets aimlessly have passed.
If they catch a good ball they will thank them for their luck and if not they will wait or try again on another day.
But now, science has made it possible to predict ocean thermal front or temperature contrast zones through satellite imagery, which are considered good catches.
The remote sensing satellites of the National Institute of oceans are one step ahead of Incois (NIO)
A unique experiment to accurately predict the time required for plankton (fish feed)
This contrast temperature zone on the Indian coast grows and predicts the maximum concentration date of marine supplies and fish.
The availability of fish and other marine species in the ocean is not evenly distributed, but they are concentrated in high chlorophyll areas or temperature contrast areas (
A joint place where warm water and cold water are vertically mixed to encourage the growth of more plankton and plankton, which in turn act as fish feed to attract marine life into the area).
Neo's Marine discoverer project is using an enclosure tank as a simulator to study the changing biology and response time of plankton and marine organisms in these thermal front.
Experiments and accurate predictions were carried out in order to increase catches and save time and fuel costs.
"After Gujarat and Goa, the experiment was recently completed 40 kilometres from the coast of Visakhapatnam, where the research vessel RV Sindhusankalp was used.
This experiment will be done at Kochi by the end of this year, and then we can finish Rs 70-
Crore project funded by CSIR (
Council for Scientific and Industrial Research)
2017, "says scientist VSN Murty. in-
Head of the Neo Regional Center.
VVSS Sarma, chief scientist and project leader of ocean Finder, explained the technology used in the experiment, saying, "the thermal front constantly moves its position and changes with the flow of water and tide.
They may maintain a strong and stable front in a few hours to about a week, which can continue to extend in the ocean, such as 10 kilometers to 50 kilometers.
In our experiments, we tried to identify these stable frontiers of plankton growth and marine migration.
Next, we have deployed 10,000 liters of containment tanks, which will power the sea surface.
Water in the front area.
The tank is rusty.
Waterproof marine steel metal frame as boundary and transparent plastic sheet, stored in water.
The buoy has been installed to allow the tank to float in the middle.
Another similar tank was also deployed, where normal sea water from non-oceans
Fill in the front area as a reference.
Now, the two are monitored to understand the growth rate of plankton, plankton, bacteria and other microorganisms
Creatures from a few days to a week.
The growth reaction varies depending on the background of water (
Salinity, pH, presence of nutrients, etc).
Therefore, the response time was calculated, and then the fishermen were predicted on the catch.
"In the water tank, nutrients --
Rich deep water mixed with seawater in different proportions
10: 90, 20: 80, 30: 70.
It was found that the strong mixing of the ratio of 20: 80 gave the best and fastest reaction in terms of plankton growth.
This is the first time that India has used this enclosure technology, which is usually used in Germany and Sweden.
"This successful experiment with precise predictions will certainly bring great benefits to fishermen," Sarma added . ".
