Press Release on Fish Farming Research: September-2018

Moving fish farms enables seagrass meadows to thrive, study shows

Commercial fish farms ought to be affected off from seaweed meadows so as for each to thrive within the future, consistent with new analysis.

The meadows boost human well-being and therefore the economies of coastal communities, however, waste from finfish cultivation is understood to possess broken seaweed populations worldwide. [1]

Use of Spirulina platensis in the treatment of fish farming wastewater

Each year, the quantity of fish made around the world will increase, that contributes to many surroundings impacts akin to the disposal of effluents while not treatment within the environment. This scientific work had as main objective the event of Spirulina platensis in fish effluents, an occasional price medium for the assembly of biomass, so as to cut back the degree of some inorganic nutrients to succeed in the allowed parameters by the Brazilian environmental standards for effluent disposal and to alter utilize of the water. river Tilapia (Oreochromis niloticus) fingerlings were made in H2O. The effluent generated by the culture was transferred to a pool wherever H2O was additional until the salinity often ‰ was reached. [2]

Impact of intensive fish farming on methane emission in a tropical hydropower reservoir

Fisheries and cultivation area unit necessary sources of food for many legion folks around the world. World fish production is projected to extend by V-J Day within the next ten years, reaching around two hundred million tonnes p.a.. the most driver of this increase is going to be supported fish farming management in developing countries. In Brazil, fish farming is increasing because of the climate conditions and huge offer of water resources, with the assembly system supported Nile genus Tilapia (Oreochromis niloticus) farming in reservoirs. upcountry waters like reservoirs area unit a natural supply of gas (CH4) to the atmosphere.

Suitability of Ground Water Quality in Kala Khatae District Sheikhupura for Fish Farming

The economically profitable production of fish and different aquatic organism in cultivation depends on an appropriate surrounding during which they will reproduce and grow. as a result of these organism sleep in water, the main environmental concern inside the culture system is water quality. The physio-chemical and biological characteristic within the fish lake offers the foremost favorable conditions for the existence of fish also as different aggregation that represents essential elements of the organic phenomenon. The survival and optimum growth of cultural fish basically rely upon the nice water quality. The aim of the study to supply a summary of quality for work by analysis of well water. Water samples from twelve sites in triplicate were collected every which way from totally different villages of Kala Khatai District Sheikhupura in March-April 2016. [4]

Present Status of Pond Fish Farming: Evaluation from Small Scale Fish Farmer under Saidpur Upazila, Nilphamari, Bangladesh

The present study was conducted underneathstand|to grasp} the standing of lake fish farming in Saidpur Upazila under Nilphamari district of the Asian country. The survey analysis was conducted on forty fish farmers throughout Oct 2016 to March 2017). Farmers were haphazardly elite from elite areas. Primary knowledge was collected through a survey questioner; secondary knowledge was collected from the relevant literature. The average size of lakes was 8-30 decimals and containing 3-6 month water holding capability with sixty-fifth seasonal pond. Average stocking density was found 1500-2000 fry/ha. [5]
