Abstract The economic potential of outdoor microalgal bacterial floc (MaB-floc) raceway ponds as wastewater treatment technology and bioresource of biomass for fertilizer, shrimp feed, phycobiliproteins and biogas in Northwest Europe is assessed. This assessment is base...

The main purpose of this research is to analyze economic feasibility of biodegradable sonw crab gill netmodel project. The results of benefit/cost analysis show that use of the biodegradable gear is economicallyfeasible. Assuming that the rate of gill net lost is 5 perc...

The best documented method to decrease predation of breeding seabirds by gulls are culling regimes; however, studies on the effectiveness of this method show ambiguous results. Here we tested an alternative method, using bamboo canes erected in four breeding sites of Ar...

A major challenge in aquaculture is finding nutrient resources that do not compete with human demand and do not threaten ecological sustainability. Single cell proteins, such as filamentous fungi and yeasts, have similar nutrient profiles to fish meal, grow fast under o...

Upon colonizing new habitats, invasive species face a series of new selection pressures as a result of changing abiotic conditions and novel biotic interactions with native species. These new selection pressures can be accommodated by different mechanisms that act on di...

Commercial yields of perch, Perca fluviatilis (L.), from Upper Lake Constance changed markedly during the 20th century. The perch boom in the 1950s and 1960s is attributed to higher fishing intensity and lake eutrophication. Decreasing yields in recent decades are mainl...
