Metadata: 0201C- West coast lochs- small pelagics acoustic survey-Clupea cruise 0201C
Abstract:
Daily folders (10) of Simrad format (.ek5 format). CTD data for 24 vertical dips. Continual AGDS data for 38 and 120Khz frequencies. Objectives: To sample fish and benthos in designated sealochs using the BT154 trawl and 2.8m beam trawl. To carry out detailed acoustic surveys in lochs using Reson 6012 multibeam and Roxann. To carry out grab sampling for benthic organisms and ground truthing Roxann. To carry out plankton and CTD sampling at selected stations within the lochs.

Internal code | Internally assigned metadata identifier | 6221 |
Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 0201C- West coast lochs- small pelagics acoustic survey-Clupea cruise 0201C |
Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Herring, sprat,west coast, lochs,acoustic survey, Clupea |
File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | Marine_Scotland_FishDAC_1736 |
Resource Identifier | This is the code assigned by the data owner. | Marine_Scotland_FishDAC_1736 |
Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2001-01-26 |
End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2001-02-08 |
Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 55000.00 |
Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/resources/uom/gmxUom.xml#m |
Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | Not Planned |

Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Where possible hauls were of 30 minutes duration. In total seven Pelagic, nine demersal and eight beamtrawlswere carried out. Fortygrab stations were undertaken for sediment analysis andground truthing RoxAnn, 24 CTD stations and seven plankton stations were also sampled. The thermosal inograph was run continuosly throughout the working day. The size range of the most commonly occurring species (herring sprat, whiting, pout and poor cod) are shown for each loch in graphs 1-5. Euphausids were also present in large concentrations, primarily associated with sprat in 60-80 m depth. Haddock were caught in significant numbers in only one haul in Loch Hourn, ranging in size from 14-22 cm, and averaging 18 cm. A detailed species list for each loch is shown in Tables 1 and 2. Samples of herring were retained for DNA analysis. Herring were also examined for sex, maturity and lcthyophonus infection. Female herring accounted for 45% ofthe catch. All herring were stage 1 maturity and no lcthyophonus was found. Stomach samples from herring, whiting and saithe were taken and preserved for analysis. It is interesting to note that saithe captured near a fish farm contained only fish pellets in their stomachs. All hauls were sampled according to standing instructions and otiliths taken where necessary. Gear The PT154 net was used very successfully as both a pelagic trawl and a demersal trawl capable of fishing for Nephrops. The net was modified by replacing the two wing weights with a fully rubbered chainground gear of equivalent weight. The footrope was attached to this additional ground gear by adjustable strops every metre. Evenwhen fished hard on the seabed the gear remained stable, successfully capturing Nephrops norvegicus down to 12 mm carapace length and Calocaris macandreae . Creels in the sealochs are still a major problem when trawling, however before the trip began every effort was made to contact as many fishermen as possible who creeled in the lochs prior to commencingwork. This enabled trawling to be conducted in areas that would otherwise have been avoided due to the risk of creel damage. Gaining a knowledge of the shooting patterns employed bythe fishermen made asignificant difference to the success ofthe tripand this type of cooperation should be encouraged. |
