Fishing - Raising / Fishing - Production

FISH🐠 - Production is a rich and inexpensive source of fish protein in our diet.  Fish production includes fish as well as shellfish such as shrimps and mussels.
There are two sources of fish:
(1) A natural resource called fishing.  And
(2) another source of fisheries is called fish breeding
The water sources of fish are seawater and salt water.  Alkaline water is found in rivers and lakes.  That is why fishing and fish breeding can be done in sea and freshwater habitats. 

( i ) Marine Fisheries
India's marine or marine fisheries resource area up to a depth of 7500 km of coastline and beyond Is.  The most prevalent marine fish are pomfret, mackerel, tuna, sardines and Bombay duck.  Different types of nets are used to catch marine or marine fish from fishing boats.  Satellites and echo-sounders can detect large groups of fish in the open sea and increase fish production using these instructions.  Some economically important marine fish are also bred in seawater.  These include mullet, bhetki and povspot  shellfish, such as shrimp mussels and esters (pearl oysters) as well as marine weeds that are also used to breed pearl oysters to obtain pearls.  In the future, in case of scarcity of marine fish stocks, these fish can be supplemented by breeding.  This system is called marine culture. 

(ii)Inland fisheries: 
Inland fisheries are freshwater sources, canals, lakes, water museums and rivers.  Saline water resources, where seawater and freshwater are mixed such as estuaries, lakes are also important fish reservoirs.  When fish are harvested at endoplasmic reticulum, production does not increase.  Most of the fish production from these sources is done through water conservation.  Fish-breeding is sometimes done with paddy crop as well.  More fish culture can be done with mixed fish culture system.  Domestic and imported fish are used in this operation.  Such systems use 5 or 6 species of fish in a single pond.  It selects fish that cannot compete for food or have different diets.  The result of this The food in each part of the lake is used.  Such as how many fish feed on the surface of the water.  The Rohu fish feed from the middle of the lake.  Miguel and Common Kape get food from the bottom of the lake.  Grass carp eat weeds.  This type of fish, despite living together, feeds on its own without competition.  This increases the fish production in the lake.

One of the problems in mixed fish culture is that some of these fish breed only in the rainy season.  Even if the mashed egg is taken for the native species, it can be mixed with the eggs of other species.  Hence the lack of availability of good quality dibho for fish breeding is a serious problem.  Methods are being explored to solve this problem so that these fish can be bred in the pond through the use of endocrine glands.  This results in a voluntary supply of pure fish denim.
