Abstract:
... Fish culture plays an important role in supplying high-quality proteins and omega-3 (n-3) long-chain polyunsaturated fatty acids. Aquaculture has been the fastest growing sector in agriculture. Fishmeal is an important component of commercial fish feeds, but ensuring a sustainable supply of fishmeal is in question. A good source of proteins in aquafeeds is insects. For the past 20 years, investiga ...

Abstract:
... This study provides a broad discussion on the tilapia culture chain in Brazil. It aims to analyse the business environments of tilapia culture zones in Brazil, supported by the Global Value Chain (GVC) approach. For this purpose, this study used a wide range of multidimensional indicators collected from tilapia production units (TPUs) and distributed in four selected and categorised production zon ...

Abstract:
... Feed accounts for 60–80% of tilapia production costs, and high feed cost and limited feed access are major issues faced by fish farmers. A potential solution is for farmers to produce their own feeds using cheaper and locally available ingredients. This paper evaluates the feed formulation training implemented in Ghana as part of the Fisheries Commission's activities under the Ghana Aquaculture fo ...

Abstract:
... The aim of this study was to assess the levels of heavy metals in both wild and farmed tilapia on Lake Kariba in Zambia and to evaluate the impact of intensive fish farming on wild tilapia. Three sites for wild fish (2 distant and 1 proximal to fish farms) and two fish farms were selected. One hundred fish (52 from distant sites; 20 near fish farms; 28 farmed fish) were sampled and muscle tissues ...

Abstract:
... Effective fishway design requires knowledge of fish swimming behavior in streams and channels. Appropriate tests with near-natural flow conditions are required to assess the interaction between fish behavior and turbulent flows. In this study, the volitional swimming behavior of S. prenanti was tested and quantified in an open-channel flume with three (low, moderate, and high) flow regimes. The re ...
fish; fish allergies; fish consumption, etc ; allergenicity; allergens; cross reaction; epitopes; hunger; immune system; protein conformation; risk; Show all 11 Subjects
Abstract:
... People eat many varieties of food to satiate their hunger. Among them, a few numbers of food cause overreaction of the body’s immune system, and fish holds a permanent position on that list. Processing methods, including one treatment or a combination, can have different effects on the allergenic potential of food proteins. An important point to note, however, is that not all of these methods can ...

Abstract:
... Marine protected areas (MPAs) have been established across the globe to mitigate the effects of multiple stressors on marine communities. In many locations, MPAs have generated positive effects on fish communities, but the impacts of fishing pressure—the primary stressor MPAs seek to manage—have not been well investigated. We examined changes in fish biomass inside and outside of no-take MPAs over ...

Abstract:
... The objective of this study was to investigate the effect of papain on the physicochemical and microbiological properties, volatile compound profiles, and sensorial attributes of Chouguiyu. Papain was applied at a dose of 10, 50, 200, 400 U/g fish. Results showed that papain addition improved the release of free amino acids, essential amino acids, eicosapentaenoi acid (EPA, C20:5n3), and docosapen ...

Abstract:
... Marine species may respond and adapt to climate change through shifting spatial distributions, but options may be limited by the occupancy of essential habitats which are anchored in space. Limited knowledge of when spatial constraints are most likely to occur in marine fish life cycles has impeded the development of realistic distribution forecasts. In this study, we develop and implement analyti ...

Abstract:
... Behavioural responses of fishes to littoral zone habitat enhancements are relatively understudied in diverse fish communities but are critical for understanding overall fish community responses. To advance knowledge on effects of coarse woody habitat (CWH) littoral zone enhancements, we initiated a long‐term study on Sanford Lake, Vilas County, Wisconsin, where 160 trees were added to the littoral ...

Abstract:
... The fish processing by‐products are generally predicted as low‐cost resources and used as feed for aquaculture and fertilizers for agriculture. This study aimed to extract collagen type‐I from fish‐discarded skin and their application in the fabrication of active food packaging films. Carboxymethyl cellulose (CMC) was used in collagen films as a cross linker and Berberis lyceum root extract (BLRE) ...

Abstract:
... Unusual behavior has been noted in Paramisgurnus dabryanus loaches, which have been seen to float on the water, both on aquafarms and laboratories. Animal behavior usually reflects adaptation to the environment, but this “floating” behavior undoubtedly increases the risk of being predated. In order to understand the ecological significance, we first studied the basic characteristics of this behavi ...

Abstract:
... Bycatch reduction devices (BRDs) allow selective release of unwanted fish (bycatch) during fishing operations, while retaining target fish. Existing BRDs use passive methods, exploiting differences in fish behavior, size, and/or shape to separate bycatch from target species. Recent availability of practical systems transmitting real-time video from trawls to the towing vessel during routine fishin ...

Abstract:
... In contrast to collagens 1α1 and 1α2, the more obscure collagen 1α3 is sparsely mentioned in literature. In skin collagen type 1 of teleosts (bony fish), however, the chain occurs in a heterotrimer together with collagens 1α1 and 1α2, which makes it one of the most abundant proteins in teleosts. As teleost fish species and gelatin (hydrolysate) prepared from their skin are a major source for food ...

... Benzophenone (BP) derivatives (BPs) ultraviolet filters are used in industrial and commercial products and have been reported to be toxic. Studies have investigated the ecological risks but not the human exposure risks of BPs. Residues of 10 BPs (BP, BP-1, BP-2, BP-3, BP-8, 2-OHBP, 4-OHBP, 4-MBP, M2BB, and PBZ) were measured in 110 commercial samples of saltwater fish (SF) and freshwater fish (FF) ...

... Preserving the quality of fish is a challenging task. Several different cooling methods and materials are used during their storage, transportation purpose. These are responsible factors that decide the freshness of a post harvested fish. In this proposed algorithm, a computer vision-based technique is developed to predict the freshness level of fish from its image. Eyes of the fish are considered ...

Abstract:
... Australia has experienced a significant increase in seafood imports over the past two decades. Concurrently, Australian seafood producers have raised concerns that the low market prices of imported fish may negatively affect the prices of domestically produced seafood and, subsequently, the profitability of the Australian fishing industries. To validate this concern, this study examines the relati ...

However, little is known about the contamination of these parasites in raw fish in Southeast Asia, where the consumption demand of uncooked fish is increasing. In 2019, the occurrence of several cases of raw yellowfin tuna (Thunnus albacares) obtained from retail shops with the presence of unknown white, ...
