FISH DETECTION [7 records]

Subject field(s)
  • Scientific Research Equipment
  • Fish
CONT

Five sites representing a broad range of fish pass types were selected for trials. Camera, lighting and image recording equipment were deployed at each site, to identify the optimum combination and arrangement to produce the best fish images. The resulting video output was used to develop and evaluate three computer-based image analysis systems for detecting fish from video images. Two of these significantly [outperformed] the third in terms of detection rate for fish and time taken for an analyst to obtain a fish count.... The project generated [a] fish counting system... suitable for fish passes and narrow channels...

CONT

... the industry standard for fish detection are split-beam echosounders. In ideal survey conditions, their echograms provide a clear image of fish as they travel through the beam of ensonified water. For high-energy tidal channels, the conventional processing approach is to limit the depth range by excluding the surface as it is difficult to distinguish bubbles from fish in areas of entrained air... When fish form dense aggregations, it can be difficult to acoustically identify an individual fish from its neighbour when the signal is over-saturated.

En la actualidad, llamamos SONAR a cualquier sistema que, haciendo uso de las ondas de sonido que se transmiten a través del agua, pueda localizar un objeto sumergido. Este instrumento comenzó siendo conocido de una manera bien distinta. El sistema era llamado ASDIC, un nombre que se correspondía con las siglas del proyecto antisubmarino que estaban llevando a cabo los aliados (Anti-Submarine Detection Investigation Committee) al final de la Primera Guerra Mundial.

CONT

Near infrared microscopy has shown potential to discriminate bone particles of fish origin and those of terrestrial animal origin in the sediment fraction of feedstuffs. In this study, the use of this method for the detection of processed animal proteins in the flotate is investigated. First, we show that it is possible to recognize animal particles in the flotate based on a spectral analysis. Secondly, the analysis of several spectra indicates that the near infrared microscopy could differentiate classes of animals.

Key term(s)

CONT

La microscopie en proche infrarouge (NIRM) a démontré son potentiel pour discriminer les particules d'os de poisson de celles des animaux terrestres dans la fraction sédimentée des aliments composés pour animaux. L'identification de traces de protéines animales transformées (PAT) par cette technique est basée sur l'évaluation des spectres obtenus à partir des particules individuelles présentes dans l'échantillon. Les présents travaux apprécient les performances du NIRM pour la détection des particules d'origine animale dans le flottât des aliments. Premièrement, il est montré qu'il est possible de reconnaître des particules d'origine animale dans le flottât sur base de leur spectre. Deuxièmement, l'analyse de plusieurs spectres indique que le NIRM pourrait différencier des classes d'animaux.

Fisheries and Oceans Canada. The Quality Management Program(QMP) is an enhanced inspection program that requires all registered plants to develop and implement an in-plant quality management program. The program provides added assurance that fish products produced in Canada comply with regulatory requirements. The Program relies on the basic concepts of detection and prevention. It enables the fish-processing industry to monitor its own compliance with regulations and to identify and quickly deal with problems in processing operations.

Pêches et Océans Canada. Le Programme de gestion de la qualité (PGQ) est un programme d'inspection amélioré dans le cadre duquel toutes les usines de transformation du poisson enregistrées doivent élaborer et appliquer un programme de gestion de la qualité en usine. Le programme est une garantie additionnelle que les produits du poisson fabriqués au Canada respectent les exigences réglementaires.
