Direct measurement of swimming and diving kinematics of giant Atlantic bluefin tuna (Thunnus thynnus)

Tunas possess a range of physiological and mechanical adaptations geared towards high-performance swimming that are of considerable interest to physiologists, ecologists and engineers. Advances in biologging have provided significant improvements in understanding tuna migrations and vertical movement ...

A method to extract fishers’ knowledge (FK) to generate evidence for sustainable management of fishing gears

The dangerous effects of Abandoned, Lost or Discarded Fishing Gears (ALDFG) is documented in the literature. However, there exists an overall lack of understanding in quantifying the pollution loads of fishing gears (FG) in territorial waters or on the beaches. The lack of data on FG life cycle results ...

Comparative Structural and Antigenic Characterization of Genetically Distinct Flavobacterium psychrophilum O-Polysaccharides

Little is known about the underlying basis of serotype specificity among strains of Flavobacterium psychrophilum, the agent of rainbow trout fry syndrome and bacterial cold-water disease. The identification of different heat-stable O-serotypes among strains of this gram-negative pathogen does, however, ...

Clustering of Vibrio parahaemolyticus Isolates Using MLST and Whole-Genome Phylogenetics and Protein Motif Fingerprinting

Vibrio parahaemolyticus is a ubiquitous and abundant member of native microbial assemblages in coastal waters and shellfish. Though V. parahaemolyticus is predominantly environmental, some strains have infected human hosts and caused outbreaks of seafood-related gastroenteritis. In order to understand ...

Global Proteomic Analysis of the Resuscitation State of Vibrio parahaemolyticus Compared With the Normal and Viable but Non-culturable State

Vibrio parahaemolyticus is a common pathogen which has become a major concern of seafood products. The bacteria in the viable but non-culturable (VBNC) state are unable to form colonies on growth media, but under appropriate conditions they can regain culturability. In this study, V. parahaemolyticus ...

Changes in precipitation may alter food preference in an ecosystem engineer, the black land crab, Gecarcinus ruricola

Gecarcinid land crabs are ecosystem engineers playing an important role in nutrient recycling and seedling propagation in coastal forests. Given a predicted future decline in precipitation for the Caribbean, the effects of dehydration on feeding preferences of the black land crab Gecarcinus ruricola ...

Modulation of stress response and productive performance of Litopenaeus vannamei through diet

The high tolerance of Litopenaeus vannamei to a wide range of salinity (1–50 psu) makes this species an excellent candidate for culture under low salinity, decreasing shrimp epidemics and water pollution in some coastal areas. However, salinity levels outside the optimal range could impose several physiological ...

Ecosystem effects of fishing & El Niño at the Galápagos Marine Reserve

The Galápagos Archipelago is home to a diverse range of marine bioregions due to the confluence of several cold and warm water currents, resulting in some of the most productive tropical marine ecosystems in the world. These ecosystems are strongly influenced by El Niño events which can reduce primary ...

Further characterization of the zebrafish model of acrylamide acute neurotoxicity: gait abnormalities and oxidative stress

Occupational, accidental, or suicidal exposure to acrylamide (ACR) may result in a neurotoxic syndrome. Development of animal models of acrylamide neurotoxicity is necessary for increasing our mechanistic understanding of this syndrome and developing more effective therapies. A new model for acute ACR ...

Responses of microbial community structure in turbot (Scophthalmus maximus) larval intestine to the regulation of probiotic introduced through live feed

Various bacteria that adhere to the gut are important for the health of fish. Regulating the microbial community in a desirable direction may be beneficial in aquaculture for preventing and controlling the diseases caused by pathogenic microbes. In this study, we investigated the changes in the microflora ...

River metrics by the public, for the public

Managing rivers in society’s best interest requires data on river condition. However, the complexity of river ecosystems, combined with finite budgets for river monitoring and modeling, mean difficult choices are necessary regarding what information will be available. Typically, decisions of "what to ...

Packaging method using dry ice snow

The present invention provides a modified atmosphere packaging method, comprising the following steps: providing a modified atmosphere packaging (1,5,9) made in a gas impermeable material, the packaging is heat sealable at a heat sealing section and comprises at least one one-way valve (6) for allowing ...

Method for processing a food product and corresponding processing apparatus

A method for processing food products is disclosed that comprises a step of preparing a food product during which one or more raw materials, which constitute the food product to be obtained, are worked, a cooking step during which the food product previously processed during the preparation step is ...

Extraction and concentration of food flavours

A method for extracting and concentrating the flavours of one of more foodstuffs, including the steps of (a) cooking the foodstuff or foodstuffs under vacuum for a duration of 1 to 15 hours, preferably between 1.5 and 13 hours, at a temperature of between 50 and 90° C., preferably between 70 and 88° ...

Eviscerating device and method for eviscarating fish

Disclosed is a gutting device (1) for gutting fish (9), said device having gutting tools (3) arranged above a processing line (100), which gutting tools can be controlled into and out of the opened abdominal cavity (93) of each fish which is conveyable in a supine position and a longitudinal orientation. ...

Apparatus and method for automatically monitoring an apparatus for processing meat products

The invention relates to an apparatus for automatically monitoring an apparatus for processing meat products, in particular fish, comprising a prediction unit for determining a yield-relevant prediction variable, the prediction unit being connected to input sensors for acquiring geometric and/or weight ...

Climate change, food security and health in Kiribati: a narrative review of the literature

ABSTRACT Background: Climate change is recognised as having a ‘multiplier effect’ on food insecurity and adverse health experiences of communities in the Pacific region. Islands are especially at risk due to their limited land availability, population pressures and, in the case of atolls, their low-lying ...

Marine Natural Products from Microalgae: An -Omics Overview

Over the last decade, genome sequences and other -omics datasets have been produced for a wide range of microalgae, and several others are on the way. Marine microalgae possess distinct and unique metabolic pathways, and can potentially produce specific secondary metabolites with biological activity ...

Study on biochemical divergences of the meat and egg of freshwater prawns (Macrobrachium rosenbergii)

Abstract Aquaculture of freshwater prawn (Macrobrachium rosenbergii) is an important fishery sector in Asian countries. The biochemical characteristics including proximate compositions and taste components of cultured freshwater prawns were analyzed for different gender and their egg. Freshwater prawns ...

Species-Specific Discrimination of Insect Meals for Aquafeeds by Direct Comparison of Tandem Mass Spectra

Simple Summary Aquaculture is amongst the most efficient ways to produce animal protein for human consumption, and this sector is expected to continue to grow worldwide. Inclusion of novel protein sources, like insect meal, may help to mitigate the expected scarcities of feed resources and reduce environmental ...
