IFF installation at a Lobster farm, Selsey UK - Case Study
We achieved several firsts thanks to the installation of the IFF System in Selsey. Not only was it the first commercial installation in the UK, but it was also our first collaborative project with Oxysystems Ltd. The complete system had been configured and tested ex-works before shipping, just as in any other situation. There were numerous walls to drill upon our arrival on site, and the ...

Is The Anti-Seepage Geomembrane In Fish Ponds Harmful To Fish And Shrimp?
Fish pond anti-seepage geomembrane is one of the used geotechnical materials for small family fish farming, ornamental fish ponds, and large fish pond liners. The reasons for using this material are as follows: First, the cost of the anti-seepage geomembrane material is much lower than that of concrete; the second is that the construction of the anti-seepage geomembrane material is more ...

Project - Artificial Reefs
In collaboration with local fishermen, we are installing a network of simple, low cost artificial reefs to act as alternative fishing grounds, relieving pressure of over-fished reefs Our first artificial reef project was launched in October 2016 in the Bay of Ranobe. We install simple, affordable, and replicable artificial reefs on degraded patch reefs across the Bay of Ranobe to act as ...

Shrimp Farming Guide For Beginners
Shrimp is a common food on the table. There are many varieties of shrimp. Each type of shrimp has its own characteristics. The freshwater shrimp and sea shrimp are rich in nutrients and taste slightly different. Nowadays, the scale and quantity of farmed shrimps are rising, and the technology of raising shrimps is also very mature. However, for some beginners, there is still much knowledge to ...

Sustainability requires that we learn to embrace change, not fight it
Instead of engineering nature into standardized systems of production, we should look for ways to integrate our lifestyles within the cycles of the world around us. Limits to growth are a fundamental and widely accepted principle of sustainability. You might even call them the first law of sustainability. Nevertheless, as ecological economist Richard Norgaard first noted, limits make a terrible ...

Climate resilience (with oysters)
Earth’s rising temperatures mean more glacier melt, sea-level rise and severe weather, and this translates to heightened threats for coastline communities. In response, SCAPE Landscape Architecture — powered by President Obama’s Rebuild by Design Initiative — has proposed an innovative way to protect coastlines that also promotes biodiversity, environmental education and ...

Nets That Save Fish - Ocean bycatch isn’t inevitable — it’s a design challenge.
Six years ago, the Norwegian coast guard filmed a Scottish fishing vessel riding gray swells, dumping 5 metric tons of dead fish back into the North Sea. Over the European Union catch quota, and so unable to keep all the fish they’d caught, the fishermen had to ditch some. To the Norwegians, who aren’t part of the EU and hold a strict discards ban, the waste was shocking. When this ...

Development of new methods to assess invertebrate immunology and immunotoxicology in aquaculture: oysters and lobsters as examples
In order to support healthy aquaculture, we developed assays to assess immune functions and their susceptibility to environmental conditions or toxicants. Flow cytometry allowed the rapid and quantitative analysis of oyster and lobster cell subpopulations and their functions (phagocytosis, peroxide production, natural killer cell-like activity and apoptosis). We demonstrated experimentally that ...

Mapping the risky decision space of commercial rock lobster fishermen
This article explores how commercial rock lobster fishermen from a small fishing town in South Eastern Australia make decisions about two important issues: whether to fish on a particular day and when to wear a life jacket. The analysis of the decisions integrates personal, social and cultural factors into a display of the fishermen's 'decision-space'. The outcome of these decisions has the ...

Mitochondrial DNA variation in the European lobster ( Homarus gammarus) throughout the range
The genetic differentiation of the European lobster (Homarus gammarus) was investigated in 3,283 individuals from 44 population samples throughout its geographical distribution (Norway to Greece) by means of polymerase chain reaction restriction fragment length polymorphism analysis of a 3-kb mitochondrial DNA segment. Ninety composite haplotypes were revealed with the number of haplotypes in ...
