Modeling fish production for Southern California's petroleum platforms
California's oil platforms are nearing the end of their productive lives, and therefore will be decommissioned in the near future. These structures have been shown to be important habitat for both settlement and growth for reef fishes. Important information on the biological effects (i.e. loss of biomass and production) of different decommissioning options has not yet been explored in detail. ...

The effects of surface water abstraction for rice irrigation on floodplain fish production in Bangladesh
Abstraction of surface water for irrigation poses a serious threat to the sustainability of floodplain fisheries in Bangladesh. Previous fisheries research has accorded a central role to dry-season (Rabi) water maintenance in safeguarding the health of the fishery, but rice irrigation water abstraction dries up water bodies at a rapid rate. Having reviewed various aspects of this water ...

Improving fish farmers’ climate change adaptation strategies through information utilisation in Akinyele local government area of Oyo State, Nigeria: implication for sustainable fish production
This paper assesses the information utilisation by fish farmers on climate change adaptation strategies with the view of improving their adaptation to climate change and as well increasing fish production in Nigeria. A survey was carried out to obtain data from the farmers. The data collected were analysed by using frequency count, mean and percentage. Information that could have improved ...

Assessing the roles of environmental factors in coastal fish production in the northern Baltic Sea: A Bayesian network application
Environmental conditions play a crucial role in the distribution and abundance of fish species in any area. Much research has been attributed to the requirements and tolerance limits of commercially exploited fish species. It is rare, however, that studies have been able to address the relative importance of potentially restrictive environmental factors; extensive enough to allow for estimation ...

Haven or Hazard: The Ecology and Future of the Salton Sea
The Salton Sea, the largest inland body of water in the state of California, lies 35 miles north of the U.S.-Mexico border in one of the most arid regions in North America. With a surface elevation approximately 227 feet below that of the ocean, the Salton Sea is a study in contrasts: it is an agricultural drainage repository that provides vital habitat for more than 380 species of birds, a ...

About use of "fish meal processing machinery"
Fishmeal processing machinery mainly uses fish with low economic value, fish production and processing waste or some crustaceans and cephalopods as raw materials to produce and process into fishmeal machinery and equipment. In addition to being used for the production of fish meal for feed, if the raw materials are fresh and the facilities meet hygienic conditions, it can also be used for the ...

What is lime and what type should I use? / Aquaculture
Agricultural limestone refers to calcite (calcium carbonate) and dolomite (calcium magnesium carbonate). Liming is an effective tool in fish production and pond management. The lime used in fish ponds include: Agricultural lime, CaCO3 Hydrated lime, Ca(OH)2 Quicklime, CaO You should always choose agricultural limestone (CaCO3) for application in your fishpond. You can also use Hydrated ...

Pilot scale testing of advanced oxidation processes for degradation of geosmin and MIB in recirculated aquaculture
The presence of geosmin and 2-methylisoborneol (MIB) in recirculated aquaculture systems has a significant negative impact on the fish production due to poor flavour quality of produced fish and increased risk of rejection by fish processers. Advanced Oxidation Processes has a high potential for removal of geosmin and MIB in water and in this study UV/H2O2 and UV/O3 has been tested in pilot scale ...

Modern Project on Establishment of Fish Feed Production Plant
Fish Feed Plant Background & Necessity Along with the development of aquaculture, aquafeed industry has also made a quite fast progress, especially in virtue of continue advancement of breeding technology, the culturing mode has turned into intensive cultivation from extensive fish farming, which provides vast space for fish feed production. In line with the FAO (Food and Agriculture ...

Why Lime your fishpond? / Aquaculture
Overview: When ponds are built, the top soil is alkaline and fertile. However this soil is removed and the soil left to build dykes is less alkaline and in some cases very acidic. Ponds built in areas which have acid soils and soft water may not always perform well for fish production. Such ponds may benefit from liming if the water has a total alkalinity of less than 20 mg/l. Why Lime your ...

Ghana Fish Farming and Fish Feed Production
There are two main ways to obtain feed for fish farming in Ghana: locally produced feed and imported feed. However, fish feeds locally produced are in bad quality as most of them are not extruded. Imported feed is appropriately 30% more expensive than locally produced. So importation is not a quick fix. On average the costs for Tilapia farming in Ghana consist of 70% of the feed cost. Therefore, ...

Probiotics in Aquaculture
Aquaculture is an essential and emerging food-producing sector in the world. The fishery yearbook 2017 states that 153 million tons of total fish production used for human consumption. But the production is always hindered by disease and environmental situations. These conditions result in severe financial losses for the companies. However, the use of antibiotics in aquaculture causes the ...

Fish Feed Pellet Machine Can Produce All Kinds Of Fish Feed Pellets
Nowadays, the fish feed pellets, although specially produced for fish production, it is also a very good bait. As long as the rubber band is put on the feed pellet to fish. At present, fishing gear stores also sell rubber-coated pellets, which are very convenient to carry and use, and the effect is not bad. Full-price compound pellet feed refers to a feed mixed with various substances for the ...

Decreasing degasser aeration to increase buffer capacity
Fish and bacteria produce CO2 into the production water of RAS farms. If 100 kg of CO2 is produced in a single day, 100 kg of CO2 should be removed. Otherwise CO2 will accumulate in the system. If pH is low the accumulation of CO2 in the system is seen as elevated levels of free CO2. If the pH is higher, the free CO2 will bind in the water as bicarbonate. Accumulation of CO2 can have detrimental ...

Ghana Fish Feed Production Machine And Fish Farming Market
The growing global and national demand for fish and the dwindling supply of the Ghanaian economy is another reason for the development of aquaculture. In Ghana, more and more people are shunning red meat as a source of protein and turning to fish because of the health effects. Fish feed pellet machine can make fish feed pellets, Zhengzhou Fusmar Machinery is a professional fish feed extruder ...

What is working principle of cooking machine in fish meal machinery
I believe everyone knows that the cooking machine is the key production equipment for processing fishmeal plant. It is indirectly heated by steam or heat transfer oil to ensure that the raw fish is cooked evenly; let's take a look at how the cooking machine works. The performance characteristics of cooking machine: Equipped with an automatically controlled feeding hopper, through the automatic ...

Mummichog (Fundulus heteroclitus) continue to successfully produce eggs after exposure to high levels of 17Α‐ethinylestradiol
17α‐Ethinylestradiol (EE2) is a potent estrogen used in birth‐control pills. Previous laboratory and field studies have shown negative impacts in a variety of fish species after exposure to low levels of EE2, most notably a nearly complete shutdown of egg production. The present study demonstrates that mummichog (Fundulus heteroclitus), a small‐bodied estuarine species, is able to continue to ...
