It is best to feed the fish each morning hours and afternoon. Keep in mind that you don’t permit any uneaten food items to stay during the fish pond For most several hours. It's because it can become toxic. You will find many alternative supplementary foods obtainable for the several fish species.

Decrease stocking densities developed bigger fish, but expansion in just stocking densities was similar among Manage and Biofloc treatments.
Biofloc technology is an affordable and very affordable alternative that converts squander and toxic products into beneficial products and solutions whilst lowering servicing costs.
Additionally it is easier to convey to if a recirculating aquaculture system is just not Doing the job correctly as the color with the drinking water will transform.
In fish aquaculture production, better productivity is achieved with bigger volumes of feed, causing an increase in squander generation, which incurs environmental and economic costs. A total of twenty–30% of the full nitrogen coming into aquaculture ponds remains in the fish biomass, with the rest getting a drinking water pollutant, creating high levels of harmful substances like ammonia and nitrite [eight]. Biofloc technology (BFT) is a far more environmentally sustainable technology that works by using helpful microorganisms to soak up the ammonia and nitrite made by feed waste, feces, and urine, that happen to be naturally produced from the metabolic technique of aquatic solutions [nine]. This facilitates a self-nitrification process in aquaculture systems without the Trade of inventory h2o and is particularly attained by stimulating The expansion of advantageous microorganisms that will then be utilized for a feed supply for aquaculture species and may take in nitrogenous squander [10].
बता दें कि अन्य तकनीकों के मुकाबले बायोफ्लॉक तकनीक से मछली पालन click here करना बेहद सस्ता है. इसके अलावा मुनाफा भी अन्य के मुकाबले बेहतर है.
Biofloc technology helps minimize drinking water air pollution and the potential risk of introducing and spreading pathogens.
बायोफ्लॉक सिस्टम में पानी की गुणवत्ता कैसे बनाए रखी जा सकती है?
Biofloc fish farming is a relatively new, progressive strategy of fish farming which has gained recognition among farmers in recent years. This system consists of the cultivation of microorganisms during the h2o, which assist to break down organic and natural make a difference, including uneaten fish feed, into protein-rich biofloc that serves to be a source of foodstuff with the fish.
In addition to these variables, producers must actively deal with biofloc ponds to prevent nitrite accumulation and to keep alkalinity amounts remaining in just a wholesome array.
What's even better, the rules of Biofloc have to have hardly any financial commitment to put into practice – as only daylight, a carbohydrate resource, and ample air are essential. Biofloc systems bank photosynthesis to convert undigested feeds, squander, and surplus nutrients to the food.
Considering the fact that algae to begin with develop rapidly, as being the bacterial colony starts to dominate, the pond will switch eco-friendly another 7 days and brown the following. Because the inventory raises and the dose raises, a tipping stage will be arrived at at which the drinking water will remain brown.
