Metadata: Database of critical oxygen level (Pcrit) in freshwater and marine fishes 1974 - 2015
Abstract:
This is a comprehensive database of critical oxygen (Pcrit) values from freshwater, marine and euryhaline teleost fish compiled from published literature. The database incorporates 331 measurements of Pcrit from a total of 96 published studies and covers 151 fish species from 58 families. It provided the opportunity to critically examine methodologies for determining Pcrit as well as its usefulness as an indicator of hypoxia tolerance in fish. Additional data are included (when available) on various abiotic and biotic interactions with hypoxia and their effect on Pcrit. These included: water temperature, salinity, pH, carbon dioxide, sex, photoperiod, diet, ration size, body size (mass and length), respirometry method. The aim was to provide a widely accessible central repository of physiological trait data that will facilitate future studies of fish ecology, conservation and management.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)
| Other details | ||
| Internal code | Internally assigned metadata identifier | 10736 |
| 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. | Database of critical oxygen level (Pcrit) in freshwater and marine fishes 1974 - 2015 |
| 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. | CEFASc9a84dbd-48f5-400f-a743-00b8f452a2c8 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS21100 |
| 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 | 2014-03-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2016-01-30 |
| 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 data set was acquired by a selection of dedicated studies from 1974-2015 covering an extensive geographic coverage includes at least one entry from every continent, although North America, Europe and Australasia. The data set included details on carbon dioxide; CO2; critical oxygen tension; metabolic rate; oxygen and capacity limitation of thermal tolerance (OCLTT); physiological trait. |
