Metadata: Irish Sea Fish Egg Production Survey 2010
Abstract:
This survey series took place from 2006 to 2010 and consisted of 15 voyages. Plankton samples were collected at each site on a planned survey grid. This data consists of the numbers of fish eggs and larvae, along with associated positional data and volumes filtered. A fine mesh (80 micron) 'PUP' sampler, attached to the frame of the Gulf VII sampler, was used to collect plankton samples for analysis of zooplankton species. These were analysed under Cefas contract C3576 and are recorded separately.

| 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. | Irish Sea Fish Egg Production Survey 2010 |
| 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. | CEFASbe55a6bb-5647-4a08-b125-556bddb8123d |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS2620 |
| 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 | 2010-01-20 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2010-04-20 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | 1000 |
| Spatial resolution unit | This describes the unit of spatial resolution which for distance must be metres. | urn:ogc:def:uom:EPSG::9001 |
| 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'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The main aims for these cruises were to; - Conduct a plankton survey using a 76cm Gulf VII plankton sampler to determine the distribution and abundance of cod (- Gadus Morhua- )- ,- haddock (- Melanogrammus aeglefinus- ), and plaice (- Pleuronectes platessa- ) eggs. - Remove stage 1A and 1B gadoid-like eggs from fresh plankton samples at sea. To measure, stage and preserve these eggs in ethanol prior to species identification using a DNA technique on return to the laboratory (CEFAS). CORYSTES Cruise 06/2010: All 106 stations were successfully sampled, giving complete coverage of strata A, B, C, D and E. In total 1178 gadoid like fish eggs in early development stages 1A & 1B, between 1.10 and 1.75mm diameter were removed and individually preserved in ethanol. A plankton sample and PUP sample were preserved at each station. CORYSTES Cruise 15/2010: All 106 stations were successfully sampled, giving complete coverage of strata A, B, C, D and E. In total 403 gadoid like fish eggs in early development stages 1A & 1B, between 1.10 and 1.75mm diameter were removed and individually preserved in ethanol. A plankton sample and PUP sample were preserved at each station. CEFAS ENDEAVOUR Cruise 02/2010: Plankton sampling with the Gulf VII began at 15:35h 20 January, at 53º 15'N, 04º 50'W. The plankton sampler was equipped with a Valeport CTD, a self-logging environmental package (ESM2 logger) and a fine 80µm mesh, ‘Pup’ sampler collected supplementary environmental data and biological samples at each station. 106 plankton stations were completed, covering the whole Irish Sea from 53º 00'N to 55º 00'N, with 270µm samples being collected on each station. The pup sampler or its flowmeter were not available on every station resulting in 93 samples being taken with the 80µm mesh net. Fish eggs in early development stages and between 1.1 and 1.75mm diameter were removed and individually preserved in ethanol. A total of 182 eggs were obtained during this cruise. CEFAS ENDEAVOUR Cruise 05/2010: 106 plankton stations were completed, covering the whole Irish Sea from 53º 00'N to 55º 00'N. Fish eggs in early development stages and between 1.1 and 1.75mm diameter were removed and individually preserved in ethanol). A total of 3997 eggs were obtained during this cruise. CEFAS ENDEAVOUR Cruise 07/2010: 106 plankton stations were completed, covering the whole Irish Sea from 53º 00'N to 55º 00'N. The pup sampler flowmeter worked well on this cruise resulting in 104 samples being taken with the 80µm mesh net. Fish eggs in early development stages and between 1.1 and 1.75mm diameter were removed and individually preserved in ethanol. A total of 537 eggs were obtained during this cruise.
