PE Pond Liner for Fish Farm Project in Malaysia
PE Pond Liner is a new polymer material, which is made of polyethylene. It is the most used plastic drainage film at present and can be used in many industries. Because of its lightweight, low cost, and convenient installation, it has been used in fishery and agriculture. PE Pond Liner is used for seepage prevention and leakage prevention of fish ponds; It is also used for seepage prevention, ...

A functional hydrolysate adds value to feeds for omnivorous fish species
Omnivorous fish species are known to be less demanding in terms of nutritional and palatability requirements and yet dietary hydrolysate supplementation greatly improved production yields and margins. Several biological benefits are associated with protein hydrolysates and they have been used in finfish larval and juvenile diets for several decades now, mainly due to their high palatability and ...

Determining the Effects of Bioaugmentation in Yield and Feed Consumption in Freshwater Shrimp - Aquaculture
Based on qualitative studies performed in Taiwan that demonstrated increased yield by weight of Tiger prawns grown in commercial shrimp ponds to which a bioaugmentation product had been added, a quantitative study was undertaken to determine statistically the improved yield, if any, on Macrobrachium rosenbergii. Feed was also monitored to determine biomass conversion efficiencies. Earlier ...

Underwater Unmanned Aerial Vehicle-Future of Marine Fisheries
First of all, there is huge market space for underwater drone. In terms of Fisheries and aquaculture, China's aquaculture area is 8465,000 hectares, of which 27.38% is mariculture area and 72.62% is freshwater aquaculture area. There are 32,000 aquaculture farms in China, covering an area of 10 million hectares. It is necessary to check the temperature, salinity, PH value, dissolved oxygen of ...

Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries
The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...

Hexabromocyclododecane in consumer fish from South China: Implications for human exposure via dietary intake
Levels of hexabromocyclododecane (HBCD) were determined in 12 consumer fish species from South China. The concentrations of the sum of HBCD diastereoisomers (ΣHBCD) ranged from nondetectable to 194 pg/g wet weight, with a detectable frequency of 70%. This was at the low end of the concentration range globally observed. Carnivorous fish species contained higher HBCD concentrations than herbivorous ...

Pacific fisheries need tech to track climate impact
Climate change could benefit some Pacific fisheries, but tracking the success of adaptation needs effective monitoring, says Johann Bell. Climate change could derail plans by Pacific Island countries and territories (PICTs) to use fisheries and aquaculture to foster economic development and food security. Bottom-dwelling coastal fish are expected to be hardest hit. Under continued high ...

Massive freshwater gains from producing food at sea
Water scarcity may be the most limiting factor to increasing world food production. Irrigation water is already overdrawn beyond sustainable levels and to increase reliance on rainfed agriculture is risky, even more so with climate change. However, to promote deliberate food production at sea, both fished and farmed, and both plant and animal, requires no freshwater or land. The thousands of ...
