Dissolved oxygen (DO) is the primary determinant of fish survival in intensive production. Maintaining stable DO levels throughout the day minimizes stress, preserves feed intake, and supports robust health in high-density systems.Why Dissolved Oxygen Matters in Fish FarmingFish rely on gills for oxygen uptake. When DO is insufficient, physiologic functions falter, leading to reduced feeding, ...
Introduction: A Subtle Shift with Lasting Consequences Salinity is often associated with oceans and coastal environments, but it can also emerge in places where it’s far less expected: soils, aquifers, and freshwater ecosystems. When chloride levels increase, whether from brine spills, industrial activity, or road salts, it can elevate salinity in the subsurface. Unlike many contaminants, ...

Maintaining dissolved oxygen is essential in aquaculture. Surface aerators, which float on ponds and create large splashes, are effective for small ponds but less suitable for larger water bodies. Bubble tank aeration uses thin-film bubble technology injected directly into the water column, delivering higher oxygen transfer and more uniform distribution.Oxygen needs in aquacultureFish respire ...
Yellowtail Kingfish Production facility Atacama Yellowtail (AYT) RAS facility for production of 900 tons of Yellowtail Kingfish (Seriola lalandi) in Coquimbo Region in north Chile. Supporting the diversification efforts of the Chilean aquaculture industry, the project will offer a premium sashimi-grade fish, known in the Japanese market as Hiramasa. The project will be located in Tongoy Bay, with ...
Part of an agricultural complex, this facility produces 1000 tons of catfish annually, at a fish density of up to 400kg per 1m³. Slovakia Catfish Operational View the case study ...

At the AquaMaof R&D Center we have been conducting technology and engineering trials on new aquaculture technology developments and a variety of fish species, including Shrimp. Israel Shrimp Operational ...
A 500-ton travel lift is a powerful piece of marine handling equipment, widely used in shipyards, marinas, and industrial waterfront facilities for lifting large yachts, commercial barges, fishing vessels, and offshore support craft. At the heart of its lifting system are the slings—critical components that directly contact the vessel’s hull and carry the entire load during lifting and ...
Large areas of lakes, fjords, and coastal waters are increasingly affected by low oxygen levels. Fish kills in shallow lakes during warm, windless summer days are becoming more common, and “dead zones” continue to expand in marine environments worldwide. FrykenSpa™, a Norwegian patented innovation (Patent No. 349212, PCT pending), introduces a new way to enjoy recreational ...
Boat travel lifts are essential equipment in marinas, shipyards, and boat maintenance facilities. They are designed to lift, transport, and launch vessels ranging from small fishing boats to large yachts and commercial ships. These machines are engineered with carefully calculated lifting capacities to ensure safe and stable operation under defined working conditions.However, one of the most ...
When it comes to wastewater treatment, traditional aeration techniques do a good job at degrading all sorts of organic contaminants in wastewater. However, there’s an even better, more advanced aeration technology that takes wastewater treatment to the next level. It’s called the Nano-Bubbler. Unlike traditional aeration technologies that inject air to the water in an ineffective way ...
Maintaining an optimal dissolved oxygen balance is critical for high-performance water treatment operations. On busy days, treatment tanks exhibit active aeration as microbial processes require sufficient oxygen to function predictably. A well-managed dissolved oxygen profile supports steady, energy-efficient operation and consistent treatment outcomes.What Happens Inside a Treatment TankMost ...
Boat maintenance and repair are essential services in the marine industry. Whether for recreational yachts, fishing vessels, patrol boats, or commercial workboats, routine inspection and repair ensure safety, efficiency, and longevity. One of the most important pieces of equipment that supports these services is the boat travel lift. A boat travel lift—also known as a marine travel lift, ...

Plastics recycling The role of plastic recycling companies in reducing ocean pollution Understanding the problem: What is ocean pollution and why it matters Oceans are essential for life on Earth and play a vital role in regulating the global climate. Almost one million known species inhabit them. Oceanic phytoplankton, the foundation of the marine food chain, performs photosynthesis, producing ...
Other materials recycling Challenges and solutions in the polystyrene recycling industry From solving waste collection issues to implementing emerging technologies, the recycling industry is facing interesting challenges in tackling polystyrene (PS) recovery. Innovative solutions are essential for an industry committed to driving the circular economy.What is polystyrene and why is it so widely ...
Introduction A bloom doesn’t always arrive with a neat, predictable timeline. One week the water looks normal, the next you get green streaks along the downwind shore, then the surface turns into a patchwork. If that shift continues on to become large scale algal blooms, it’s no longer just a cosmetic issue, it’s an operational issue that requires careful management. For ...
In 1912 the city of Boerne bought the land for the Riverside Park for $1.00. In 1962 a massive flood caused extensive damage to the area, and so in 1978 the Second Cibolo Creek dam was built, thus creating the Boerne City Lake in the process. Since then incremental changes and improvements were made to the park, but never a complete overhaul. In 2023 a complete renovation and restructured of the ...
