The aim of this research was to improve nutritive value of fishmeal-based feed by lactobacilli in order to achieve satisfactory nutrient availability needed to support fish development. Feed was solid-state treated at a laboratory scale with the combination of Lactobacillus paracasei subsp. paracasei ...
Intestinal failure-associated liver disease (IFALD) is a risk of parenteral nutrition (PN)-dependence. Intravenous soybean oil-based parenteral fat can exacerbate the risk of IFALD while intravenous fish oil can minimize its progression, yet the mechanisms by which soybean oil harms and fish oil protects ...
An emergency position indicating radio beacon that includes a waterproof rigid housing, antenna, a retention carriage strap securely mounted around its exterior periphery on a spool in a storage position. In an emergency the user can unwind the retention carriage strap and form an adjustable loop in ...
The invention provides a core yarn of a tough yarn for knitting and weaving a glove and the other knitted and woven fabric which are suitable for a worker using a cutting tool to wear, are excellent in a flexibility and an economic efficiency, prevent a folded end of a hard fiber from being exposed ...
A demand valve (100) for use in a breathing equipment is provided. The demand valve (100) comprises an actuating device (110) arranged to upon contact with water move a cover (111) from a first position to a second position, wherein the cover (111) in the first position allows ambient air to enter the ...
During their lifecycle, many marine organisms rely on natural adhesives to attach to wet surfaces for movement and self-defense in aqueous tidal environments. Adhesive proteins from mussels are biocompatible and elicit only minimal immune responses in humans. Therefore these proteins have received increased ...
Human-mediated food sources offer possibilities for novel foraging strategies by opportunistic species. Yet, relative costs and benefits of alternative foraging strategies vary with the abundance, accessibility, predictability and nutritional value of anthropogenic food sources. The extent to which ...
Using as thermal reflection coating fillers is a significant recycle method for the largely available by-product of shell powders in aquaculture. However, the organics in the shell powder harm its reflection ability. To enhance the thermal reflection performance of the shell powder filled coatings, ...
An underwater surface to create a marine ecosystem located in the water in which a current flows at a predetermined speed; the surface comprising one or more blocks (100) supporting one or more members (102; 200; 300), each of which extends from one face of the block by a predetermined distance and ...
L'invenzione è un metodo per l'applicazione di rivestimenti con un grado di resistenza minimo, all’interno di un insieme di rivestimenti, dei quali viene calcolato il valore di rugosità totale nell'insieme di rivestimenti basato su un valore minimo. Lo scopo è quello di divulgare una modalità nuova ...
The application is directed to polymer coatings which can be modified to control biointerfacial interactions including biofilm formation and protein adsorption onto said coatings. The polymer coatings comprise a First Component comprising epoxide or alkenyl groups, and a Second Component comprising ...
European whitefish Coregonus lavaretus has increasingly become an important species for aquatic food production, especially in the Nordic countries. Whitefish is produced in traditional cage and pond operations, and in recirculating aquaculture system (RAS) in which, unfortunately, off-flavors and odors, ...
An in-pond raceway system (IPRS) is an effective intensive aquaculture practice for regions with high water consumption and limited land resources. Water flow and dissolved oxygen (DO) are important for sustainable aquaculture. Several innovations have been made in IPRS design and operation to increase ...
White spot syndrome virus (WSSV) is one of the most virulent pathogens of cultured penaeid shrimp. Several control strategies are used commonly to mitigate the economic losses caused by the pathogen, such as application of antiviral products at farm level. One of the most practical method for the screening ...
In the last years, studies on stress attenuation in fish have progressively grown. This is mainly due to the interest of institutions, producers, aquarists and consumers in improving the welfare of farmed fish. In addition to the development of new technologies to improve environmental conditions of ...
Two different O2 levels (normoxia: 75–85% O2 saturation; moderate hypoxia: 42–43% O2 saturation) and stocking densities (LD: 9.5, and HD: 19 kg/m3) were assessed on gilthead sea bream (Sparus aurata) in a 3-week feeding trial. Reduced O2 availability had a negative impact on feed intake and growth rates, ...
Freshwater sulfide springs have extreme environmental conditions that only few vertebrate species can tolerate. These species often develop a series of morphological and molecular adaptations to cope with the challenges of life under the toxic and hypoxic conditions of sulfide springs. In this paper, ...
Knodus nuptialis n. sp. is described from the Rio Curuá drainage, Rio Xingu basin, Brazil. It can be diagnosed from its congeners by having dentary teeth decreasing gradually in size posteriorly, outer premaxillary teeth row with five cusps, 12–15 branched anal-fin rays and a single humeral spot. The ...
Several studies have shown that the performance of a supply chain is heavily influenced by the pattern of relationships among firms. This paper analyzes the structure of relationships (network topology) that leads to the highest agility of a food supply chain when sudden demand changes occur. To do ...
The Water Framework Directive (WFD) regulates freshwater and coastal water quality assessment in Europe. Chemical and ecological water quality status is based on measurements of chemical pollutants in water and biota together with other indicators such as temperature, nutrients, species compositions ...
