Fish farming is a highly profitable business in India. There are many ways to make money from fish, fish farming is amongst the best. If you’re just starting out with a small farm, it’s important to keep these mistakes in mind so that your business succeeds.
1. High density fish stocking
The term “stocking density” refers to the quantity of fish being kept in a particular portion of the area. The density of stocking is an important environmental aspect that has a major influence on rearing fish. Numerous studies have shown that the high density of rearing increases stress and in turn, causes inhibition of growth in fish.
2. Improper feeding schedule
Much more regular everyday feeding is most likely to boost the development prices of varieties with small bellies and also continuous foraging behavior (e.g., usual carp, tilapia, and also shrimp) than for species that are hostile feeders.
Farmed fish usually are fed 1-5 percent of their body weight daily. Fish can be fed by hand, by automatic feeders, and also by need feeders. Many fish farmers like to hand-feed their fish daily to guarantee that the fish are healthy and balanced, feeding vigorously, and also displaying not a problem. Please see the feeding schedule chart on the product packaging.
3. Fish seed selection
India produces a lot of Rohu, Katla and Mirgal. This fish is very sought-after in India.
You can have 10000 fingerlings that are smaller than 50mm in size, and 5000 that are larger than 50mm in size.
Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia.
Fish seed manufacturing includes egg to spawn making for 3 days, spawn to fry nursing for 15-20 days, fry to fingerling rearing for 60-90 days and fingerling to yearling rearing for 8-9 months.
4. Wrong Mixed culture
The basic principles of polyculture involve the suggestion that when compatible coinhabiting varieties of various feeding behaviors are cultured in the same pond, all the food specific niches are made use of without detriment to one another. Ecological criteria apply an enormous influence on the maintenance of a healthy marine setting and also the production of enough fish food organisms. The water top quality parameters determined in different therapies throughout the experimental period were found to be essentially comparable and all of them were within the acceptable ranges for fish society. Some fish species are not compatible with each other and can result in various undesirable issues.
5. Improper pond management
The primary requisite of fish culture is the accessibility of land for fish ponds and quality fish seeds. Although manufacturing of seeds, might be sufficient, but rearing of those tender infant fishes in well-handled Nurseries, Rearing as well as stocking fish ponds should be thoroughly understood.
The above types of fish ponds are mostly found in Federal government-handled fish farms as well as in progressive farmers. Whereas, the major purpose is for fish seeds production or table fish production with farms. Generally, in clinical fish farming number of numerous sizes of fish ponds (as mentioned above) are required for rearing of different phases of fishes specifically:-.
(1) Nursery pond – rearing of Spawn to Fry stage (approx. Dimension 4- 15 mm) for about.
15 days.
(2) Rearing pond– rearing of fry to fingerling phase (approx. Dimension: 16-40 mm) for.
regarding 2-3 months.
(3) Stocking pond- rearing of fingerling (approx. Size 41- 150 mm) to valuable.
sizes/ grown-up fishes.

6. Water management
Achieving and keeping excellent water quality with all phases of production plays a significant duty in overall fish wellness as well as efficiency.
Water quality is the most essential aspect influencing fish health and wellness and performance in aquaculture production systems. Good water high quality describes what the fish wants as well as not what we assume the fish desires. This implies that we should comprehend the water top quality needs of the fish under culture effectively.
Different fish varieties have different requirements of water quality elements (temperature, pH, oxygen focus, salinity, solidity, etc) within which they can make it through, grow as well as reproduce.
Within these tolerance limitations, each types has its own maximum range, that is, the variety within which it grows. It is therefore extremely crucial for fish producers to guarantee that the physical and also chemical conditions of the water stay, as much as feasible, within the optimal range.
Outside these optimal arrays, fish will show inadequate growth, erratic behavior, as well as disease symptoms or parasite problems. Under extreme cases, or where the poor problems continue to be for long term time periods, fish death may take place. Fish pond water includes two significant groups of substances:
Suspended particles made from non-living bits and also extremely little plants as well as pets, the plankton.
Dissolved substances made of gases, minerals as well as organic substances.
The composition of pond water changes continually, depending upon weather and seasonal adjustments, and also on how a fish pond is used. It is the aim of good management to manage the make-up to generate the very best conditions for the fish. For producers to be able to keep optimal fish pond water high quality problems, they have to understand the physical and chemical components contributing to excellent or bad water high quality.
7. Failing to have pH and total alkalinity tested
This applies just to pond owners whose ponds get on acid soils. Low pH as well as alkalinity will certainly hamper fish production no matter just how much your fish pond price to construct or how much you invested in your fish. Have a water example tested as well as use agricultural limestone if needed.
8. Using poor genetics
Tilapia are extremely simple to fish to breed and also tilapia farmers are subsequently most to blame here. The lure to grab the very first fish you discover when your infrastructure is ready to obtain fish is excellent because you want to start farming. Nonetheless, the most available fish are often inbred and also of minimal economic worth. These fish typically have a slower development rate and also poorer return (ratio of the fillet to body) than industrial strains.
Compare the amount of fish you can generate from your fish ponds in 5 years if you use a strain that takes 5 months to get to market mass vs a strain that takes 7 months.
9. Not managing the livestock
All frequently we discover newbies plan to place fish in their systems in Month 1, leave them there till harvest dimension and then collect them for the very first time. This approach is inefficient for numerous factors, consisting of, stopping working to provide a chance to eliminate slow-growing fish, underutilises infrastructure in the early months, fish might not feed well originally as low-density cause vulnerability stress and anxiety, and it does not team fish according to dimension so the harvest consists of a series of sizes which produces advertising concerns.
It is far much better to equip the fingerlings into a small container for a minimal period– generally 1 or 2 months. They are then gathered, sorted according to size, the slow growers are thrown out et cetera are replenished into a larger fish pond at a minimized number per cubic meter, and also provided a further period of 1 or 2 months prior to repeating– harvest, kind and restock.
10. Feeding incorrectly
The feed is the fuel that enables the fish to grow. Feed too little and the fish may have fantastic genetics and excellent water quality, but they will lack the fuel that drives their growth. Equally, if you feed too much the fish cannot eat all that is provided, resulting in waste, dirtying of the water and compromising of growth. It is therefore vital to feed the correct amount of feed.
Feed quality is also vital. We have seen in our hatchery that good quality feed results in less size differentiation, much larger fish, greater survival and better water quality than in adjacent tanks being feed poorer quality feed.
