  3. Target strength of mackerel icefish (Champsocephalus gunnari) from a scattering model

    backscattered target strength (TS) of six mackerel icefish (Champsocephalus gunnari) of total length 26.8–35.0 ... cm, at 38 kHz. The model used computed tomography (CT) scans of fish to determine the sound speed and ... density throughout the fish and simulated the complex interaction of the incident sound wave with the ... applicable to fish of length 26–35 cm. Existing in situ TS estimates are for smaller fish (16–26 cm) and ...

  4. THE AUTOLINE SYSTEM – AN UPDATED DESCRIPTIVE REVIEW OF THE METHOD WITH RECOMMENDATIONS TO CLARIFY CCAMLR CONSERVATION MEASURES REGULATING LONGLINE FISHERIES WITHIN THE CONVENTION AREA

    changes are suggested clarify understanding of these measures. The paper includes a recommendation for a ... discussing circumstances and scenarios occurring with the method. A definition of the fundamental unit of ... gear (a ‘line’) for longlines is proposed for the purposes of regulation and management. Current ... review of Annex 41-01/B (2007) governing research within exploratory fisheries by WG-FSA with a view to ...

  5. A multi-frequency method for improved accuracy and precision of in situ target strength measurements

    Abstract:  The effectiveness of a split-beam echosounder system to delineate single scatterers and ... synchronized signals from two or more adjacent split-beam transducers of different frequencies. The accuracy of ... from one of the split-beam transducers, additional corresponding TS measurements can be collected with ... juxtaposed single-beam transducers. Both methods were utilized to extract in-situ TS measurements of ...

  6. Pursuit of polynyas in the Antarctic peninsula area

    influence biological activity. We pursued daily transition of coastal polynyas in the Antarctic Peninsula ... area from 1978 through 1995 using images of sea ice concentrations by the satellite microwave ... observations. A typical polynya existed off the tip of the Peninsula in 1987 and 1991. In the such years, sea ... ice cover developed extensively. Inversely, the years of the narrow sea ice cover were 1988, 1989,1990 ...

  7. Dynamic model of krill Euphausia superba swarm

    , using the 38 and 120 kHz BioSonics dual-beam hydroacoustic system, numerous swarms of krill Euphausia ... superba Dana were registered. Analysis of their physical parameters was carried out. It is known that ... . Using physical parameters of the krills' swarm (density, length), the above assumption was verified ... . It was found that the vertical density pattern of krills' swarm, with a mean density of up to ...

  9. Remarks on natural mortality of Dissostichus eleginoides in Subarea 48.3

    Abstract:  With samples originated in the Chilean longline fishery of Dissostichus eleginoides of ... the considered cases with the different growing parameters, with the exception of the case of fishing ... sites. By other hand, when comparing the different mean values of M for the different variables, it was ... hooks N° 22. The general mean value of M calculated for the 44 analyzed situations was 0.14 ± 0.03 ...
