Chitosan Film Functionalized with Grape Seed Oil—Preliminary Evaluation of Antimicrobial Activity
Although the fishing and wine industries undoubtedly contribute significantly to the economy, they also generate large waste streams with considerable repercussions on both economic and environmental levels. Scientific literature has shown products can be extracted from these streams which have properties of interest to the cosmetics, pharmaceutical and food industries. Antimicrobial activity is undoubtedly among the most interesting of these properties, and particularly useful in the production of food packaging to increase the shelf life of food products. In this study, film for food packaging was produced for the first time using chitosan extracted from the exoskeletons of red shrimp (Ar…
FISH WASTE, NOT A PROBLEM BUT A POSSIBLE SOLUTION: CHITOSAN EXTRACTS AND NEW PACKAGING POSSIBILITIES.
The fishing industry is one of the oldest industries in Europe and also one of the most important economic resources in the Mediterranean area. However, to date, in addition to creating considerable economic wealth, the various sectors (markets, restaurants, shops, etc.) also create significant levels of fish waste. If not processed or recycled adequately, these waste streams can lead to environmental degradation and severe pollution (Gao et al., 2018). Although today fish waste is considered a potential resource to generate high-added value, current practices in the fishing industry do not fully exploit its biological potential. Amongst the various possibilities for reuse, the production o…
Haemolymphatic Parameters in Two Aquaculture Crustacean Species Cherax destructor (Clark, 1836) and Cherax quadricarinatus (Von Martens, 1868)
In the last few years, there has been a notable development in the breeding of freshwater shrimp (astaciculture), which involved various species and in particular, the two Australian Parastacidae species, Cherax destructor and Cherax quadricarinatus. Information about the haemolymphatic parameters of these two species is fragmentary, and filling these gaps becomes important given their importance in aquaculture. Cellular and biochemical parameters were analyzed in both species to create a reference baseline for these parameters to identify the state of welfare or suffering of these animals. The results showed that the total haemocyte count, haemocyte subpopulations, enzymatic activities and…
Haemolymphatic parameters in two aquaculture crustacean species Cherax destructor (Clark, 1836) and Cherax quadricarinatus (von Martens, 1868)
The growing demand for animal proteins of aquatic origin such as fish, molluscs and crustaceans have prompted some European and Italian companies to focus their attention on some species of freshwater crustaceans such as Cherax destructor and Cherax quadricarinatus. They are among the largest freshwater decapods, matures early, females can lay over a thousand eggs in a single brood and has a broad environmental tolerance. All these characteristics make it highly appreciated species for aquaculture and few years ago their breeding has spread to Europe and recently also in Italy (Sicily). Although some commercial yabby farms have been studied these species from different points of view (dieta…
