Mae’r set ddata hon yn cynnwys y cyfrif rhywogaethau a’r gwerthoedd hyd o’r arolygon pysgod a gynhaliwyd ar draws amgylchedd morol Cymru gan Cyfoeth Naturiol Cymru ac Asiantaeth yr Amgylchedd Cymru cyn hynny. Cynhelir yr arolygon hyn fel rhan o waith monitro parhaus o bysgod yn eu hamgylchedd naturiol ar gyfer gofynion deddfwriaethol ac i fodloni ysgogwyr busnes. Defnyddir methodoleg lem wrth samplu pysgod morol. Mae rhwydwaith craidd o safleoedd sy'n cael eu monitro'n rheolaidd. Mae'r safleoedd hyn wedi'u lleoli mewn mathau o gynefin sy'n addas ar gyfer y rhywogaethau pysgod priodol. Yn ogystal, gellir samplu safleoedd ar gyfer gwaith ymchwiliol neu ar sail ad hoc. Unwaith y bydd sampl o bysgod yn cael ei chasglu, cânt eu hadnabod ar unwaith yn y maes, eu mesur a'u cyfrif, ac yna eu rhyddhau'n fyw o'r man lle cawsant eu dal. Golygiadau Mae rhywfaint o wybodaeth wedi’i golygu i sicrhau bod y data ar gael yn agored. Mae hyn yn cynnwys: Data trydydd parti Data a gasglwyd ar gyfer ymchwiliadau parhaus Arolygon wedi’u canslo neu heb eu cwblhau Amlder Diweddaru Mae'r data hwn yn cael ei ddiweddaru'n barhaus gyda'r rhan fwyaf o'r newidiadau'n cael eu gwneud yn gynnar yn yr hydref. Yn aml, nid yw data o dymhorau arolygon yn cael ei fewnbynnu ar adeg ei gipio a gall gymryd sawl mis cyn iddo gael ei roi yn y system. Mae'r set ddata allanol yn cael ei diweddaru'n fisol i gynnwys data newydd, a gall hefyd gynnwys cywiriadau i ddata a gyhoeddwyd yn flaenorol oherwydd gwaith sicrhau ansawdd. Rhybuddion Gwybodaeth Mae data arolygon pysgod morol ar gael o 1997 hyd heddiw. Cafeat yw bod data hanesyddol yn ysbeidiol tan 2001. Mae hyn oherwydd bod data arolygon pysgod a gasglwyd cyn 2001 yn aml yn cael ei gadw mewn cronfeydd data lleol ac nid y rhai cenedlaethol (KiEco ac NFPD gynt). Mae arolygon pysgod yn cael eu cynnal trwy amrywiaeth o ddulliau arolygu ac nid yw'r data o un arolwg o reidrwydd yn uniongyrchol gymaradwy ag un arall. Argymhellir y defnyddiwr i wirio'r dull arolygu a ddefnyddiwyd yn y data a ddarperir. Gwnawn ein gorau i osgoi problemau ansawdd data, ond gan fod y setiau data hyn yn adlewyrchu’r data sydd gennym, gallant gynnwys gwallau.

Mae cael mynediad at ddata'r tacsonau fel hyn yn cynnig nifer o fanteision. Gellir ei weld ochr yn ochr ag ystod eang o dacsonau o arolygon eraill a gynhaliwyd gan unigolion a sefydliadau amrywiol. At hynny, gellir archwilio’r tacsonau drwy eu hierarchaeth dacsonomig lawn drwy integreiddio â Rhestr Rhywogaethau’r DU, sef y gronfa ddata fwyaf cynhwysfawr sydd wedi’i churadu o dacsonomeg ac enwau bywyd gwyllt y DU.

There is a core network of sites which are regularly monitored. These sites are located in habitat types suitable for the respective fish species. In addition, sites may be sampled for investigative work, or on an ad hoc basis. Once a sample of fish is collected, they are immediately identified in the field, measured and counted and then released alive from where they were captured. Redactions Some information has be redacted to make the data openly available. This includes: - Third party data - Data collected for ongoing investigations - Cancelled or incomplete surveys - Update Frequency This data is continually update with most changes made in the early autumn. Data from survey seasons is often not enter at the time of capture and can be several months before its is entered into the system. The external dataset is updated monthly to include new data, and may also contain corrections to previously published data due to quality assurance work. Information Warnings Marine fish survey data is available from 1997 to present. A caveat being that historical data are sporadic until 2001. This is because fish survey data collected before 2001 were often saved in local databases and not the national ones (KiEco and formerly NFPD). Fish surveys are carried out by a range of survey methods, the data from one survey is not necessarily directly comparable to another. The user is recommended to check the survey method used in the data provided. We do our best to avoid data quality problems, but as these datasets reflect the data we hold, they may contain errors The data is provided as a set of related data tables due to the quantity and structure of the data. A basic understanding of fisheries science and relational databases is assumed. A strict methodology is applied when sampling for marine fish.
