Biocides are chemical substances that can deter or kill the microorganisms responsible for biofouling. The rapid expansion of the aquaculture industry is having a significant impact on the marine ecosystems. As the industry expands, it requires the use of more drugs, disinfectants and antifoulant compounds (biocides) to eliminate the microorganisms in the aquaculture facilities. The use of bioc...

The haemolymph parameters for Octopus vulgaris and the condition index at molecular level were analysed using RNA/DNA and RNA/protein ratios on animals reared in floating cage systems and naturally infected by the coccidian Aggregata octopiana. Statistical analysis showed that as A. octopiana infection increased, there was a decrease in most inorganic elements and/or in haemocyte concentrations...

Coastal aquaculture in Bangladesh consists mainly of two shrimp species (Penaeus monodon and Macrobrachium rosenbergii). Currently, there are about 16,237 marine shrimp (P. monodon) farms covering 148,093 ha and 36,109 fresh water shrimp (M. rosenbergii) farms covering 17,638 ha coastal area. More than 0.7 million people are employed in the farmed shrimp sector and in 2005-2006 the export value...

Offshore aquaculture is increasingly viewed as a mechanism to meet growing protein demand for seafood, while minimizing adverse consequences on the environment and other uses in the oceans. However, despite growing interest in offshore aquaculture, there appears to be no consensus as to what measures commonly define an offshore site or how effects of offshore aquaculture—relative to more nearsh...

Abstract The increasing growth of the bivalve‐culture industry necessitates a scientific assessment carrying capacity (CC) this aquaculture system, in order to ensure sustainability. Here, using marine plankton ecological model and food balance, bivalve CCs were estimated for zones Jiaozhou Bay (JZB), an important center China. results indicated that mainly depended on filtration rates, which t...

Recently, tilapia have become increasingly important in aquaculture and fisheries worldwide. They are one of the major protein sources in many African countries and are helping to combat malnutrition. Therefore, maintenance and conservation genetics of wild populations of tilapia are of great significance. In this study, we report the population genetic structure and genetic diversity of the re...

Protecting the remaining wild salmon stock in Norway is of utmost importance and requires that farmed cannot escape from aquaculture sites. As holes net-cages are responsible for a large fraction escaped industry has to perform frequent inspections fish cage integrity. In this paper we propose an image processing computer vision based attention mechanism towards more automated fish-cage inspect...

Aquaculture is projected to be a major supplier of marine proteins large parts the global population. This includes bivalves, which have high potential offset protein deficits, as they are highly adaptable varying water temperature, salinity, desiccation, and oxygen conditions. work part two-piece contribution on novel aquaculture technology details physical laboratory tests new cultivation sys...

The continuing decline of ocean fisheries and rise of global fish consumption has driven aquaculture growth by 10% annually over the last decade. The association of fish farms with disease emergence in sympatric wild fish stocks remains one of the most controversial and unresolved threats aquaculture poses to coastal ecosystems and fisheries. We report a comprehensive analysis of the spread and...
