Aquaculture cultivation

In this study we present a method to synthesize new heterogenous photocatalytic materials based on ternary nanocomposite ZnO/MgO/TiO2 to activate persulphate (K2S2O8) for degradation of methylen blue dye (MB) and pesticide acetamiprid that used in aquaculture and agricultural cultivation under simulated sunlight.

To the best of our knowledge, no study has investigated replacing chemical fertilizers with fish effluents in marjorana production in a combined aquaculture agriculture system. The main objective of this study was to investigate the effect of Nile tilapia (Oreochromis niloticus) fish effluent water on the growth parameters, herbage yield, and essential oil composition of sweet marjoram.

In the current study, five Lactobacillus gasseri MA strains from human breast milk were investigated for their usage potentials in aquaculture and seafood products as probiotic and bio-protective. The strains were tested for their susceptibilities to various clinical antibiotics used in fish cultivation, antimicrobial activities against seven fish pathogens, alpha-amylase enzyme activities, and susceptibilities to sodium benzoate which used as a food preservative.

In this study Physico- Chemical parameters of the untreated effluent and treated effluents of M/s ITC Ltd., Paperboards Specialty Papers Division, Bhadrachalam, was taken up. On analysis of the samples, it is observed that the Physico- chemical parameters which are in higher levels initially get reduced on the biological and chemical treatment at the effluent treatment plant of the unit.

The foremost vital purpose of victimization of smartphones is for its applications which might be downloaded from the Play store. These mobile applications empower each capture fisheries and aquaculture. Using Mobile Application, Fishermen will ready to build the duty of fishing in a more pleasant way and, on the other side; a lot of profit may be taken from cultivation by diagnosing fish health diseases in time.

Nghe An is the largest province area in Viet Nam with many favorable conditions for developing farm economy. Researching on the farm economy in Nghe An is approached in the direction of sustainable development theory and from the farm owners. Base on principle of sustainable development to survey 150 farms, which were selected by two criteria group: distribution such as mountains, midland, coast plain and types of farms such as cultivation, animal husbandry, forestry, aquaculture.

Water is the most important component of agriculture production, especially during the dry seasons when all water sources are scarce yet water needs are very high. The Mekong river delta in Vietnam is the largest agricultural and aquacultural region in the country where about half of the Delta’s land area is used for rice and upland crop cultivation.

Scirpus littoralis Schrab and Typha orientalis C. Presl are cultivated in the paddy field and in the shrimp pond in the Mekong Delta of Viet Nam for human food and providing habitat for shrimp, respectively. They are recognized as phytoremediator in brackish shrimp aquaculture wastewater treatment system. However, information on effects of NaCl on plant growth and mineral concentrations of the two species is limited. Therefore, the present study was carried out to identify salt-tolerance between the two species.

The biofouling issue is a tenacious issue throughout the history of aquaculture farming in the world, however it has elevated in priority as labour and electricity costs have arisen in recent years. Besides, fouling development is frequently fast on the grounds that the waters encompassing aquaculture activities are enhanced by natural and inorganic squanders (uneaten food, fecal and excretory material) created by high-density fish populations.

The studies on fatty acids of some strains of microalgae have been implemented (Ronquillo et al., 2012, Liang et al., 2004, Hoa et al., 2010). Still, not much studies on the nutrient content included fatty acid composition of microalgae have been carried out in mangrove area of Vietnam. Thus, present study aims to identify nutrient content of microalgae from mangroves of Xuan Thuy NP in order to contribute in improving quality of alga-based food source cultivated for coastal aquaculture.

This aquatic ecosystem is the interface between upstream freshwater flow and saltwater tidal flow, creating unique aquatic habitats with significant socio-economic importance. The area is densely populated, with many people highly reliant on aquatic ecosystem productivity and related aquaculture cultivation. This study examines changes to water resources in the Hau River mouth based on hydrological variation analysis.

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants.[1][2] Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.[3] Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.

Spirulina is a Microalgae that can be consumed by humans and animals. It is usually taken by humans as a nutritional supplement and is made primarily from two species of cyanobacteria: Arthrospira platensis and Arthrospira maxima. Arthrospira is cultivated worldwide; used as a dietary supplement as well as a whole food; and is available in tablet, flake and powder form. It is also used as a feed supplement in the aquaculture, aquarium and poultry industries.
