biofloc fish farming ppt for Dummies
फीड (चारा) लागत में कमी: बायोफ्लॉक में मछलियों को सूक्ष्मजीवों द्वारा पोषण मिलता है, जिससे फ़ीड की लागत घटती है।BFT has a lot of benefits that distinguish it from all kinds of other Superior fish farming systems, such as an ecofriendly lifestyle system with zero drain water immediately after culture. BFT is dominated about other systems due to its better capacity for reduction of environmental effect, advancement of successful usage of land and h2o, upkeep with the acceptable top quality of drinking water with negligible water utilization and Trade throughout the rearing ponds, and production of protein-loaded biofloc like a supplementary feed for aquatic organisms (Reddy 2019). Also, Arias-Moscoso et al. (2018) said that biofloc could make certain thoroughly clean water and better biosecurity by reduction of wastewater pollution together with lowering the chance of introduction and spread of disorders and pathogens.
Decreased stocking densities generated much larger fish, but expansion in stocking densities was related amongst Management and Biofloc therapies.
The authors counsel that producers undertake a closed administration system for biofloc ponds. A compartmental design – exactly where fish production and microbial proliferation manifest in independent Areas – could make managing biofloc systems much easier.
Blood from the circulatory system serves quite a few features from the survival of fish, and hematological parameters are essential indicators for assessing their physiological state, strain, immune responses, and disease resistance, in addition to reflecting the nutritional and environmental ailments, therefore detecting abnormalities linked to fish overall health position [38]. Biofloc can add to the improvement of the health and fitness of fish resulting from both equally its digestive enzyme action and physiological activity, as well as evaluation of hematological parameters needs to be a superb indicator to confirm its efficacy [eighteen]. Hematological and biochemical parameters of fish species elevated in biofloc are shown in Table three. Erythrocytes are by far the most plentiful mobile parts while in the circulatory system of fish, taking part in vital roles in fuel exchange as well as respiration of cells, along with undertaking numerous capabilities more info connected with immunity, like antiviral responses, phagocytosis or cytokine-mediated signaling [forty six].
Improved food stuff security: Sustainable biofloc fish farming can also help to boost food security by delivering a dependable source of superior-high-quality fish protein.
Stage four: Optimization of Carbon and Nitrogen: Ammonia peaks can occur as a result of nitrogen written content, so optimizing carbon sources and feed mixtures using a carbon-to-nitrogen (C/N) ratio higher than ten.
This decreases the necessity for highly-priced feed and minimizes waste whilst solving the challenge of h2o air pollution.
The greatest source of air pollution is definitely the accumulation of fish squander which might degrade the quality of the surrounding h2o.
Having said that, BFT was developed to protected fish rearing ponds from health conditions because of the pathogens available in incoming water (Hargreaves 2013). It had been reported that Jaggery-centered BFT enhanced the immunity of Nile tilapia against the pathogenic Aeromonas hydrophila
So, Later on, the event of cultivation final results applying biofloc strategies will be willing to access a broader market place.
समस्याएँ: शुरुआती दिनों में पानी के पीएच स्तर में असंतुलन के कारण मछलियों की वृद्धि धीमी हो गई थी।
Considering the fact that algae at first mature quickly, since the bacterial colony starts to dominate, the pond will flip eco-friendly the following 7 days and brown another. As the inventory increases plus the dose raises, a tipping place will likely be arrived at at which the water will continue being brown.
In 2023, Yoyon stated that they might keep on to strive to deliver guidance to help fish farming business people using the biofloc system in Banjar Town, making certain their ongoing involvement from the fisheries market.
