ForkLengthFork length (FL)1) Length of a fish measured from the tip of the snout to the posterior end of the middle caudal rays. This measurement is used instead of standard length for fishes on which it is difficult to ascertain the end of the vertebral column, and instead of total length in fish with stiff, forked tail, e.g., tuna. Mostly used in fishery biology and not in systematics. (FishBase)

2) Fork length (FL) refers to the length of a fish measured from the tip of the snout to the end of the middle caudal fin rays and is used in fishes in which it is difficult to tell where the vertebral column ends. (Wikipedia)

3) Fork length (FL) can be specified as:
  • Maximum length: Size (in cm) of the largest male/unsexed or female specimen ever caught. (FishBase)

StandardLengthStandard length (SL)1) The measurement from the most anterior tip of the body to the midlateral posterior edge of the hypural plate (in fish with a hypural plate) or to the posterior end of the vertebral column (in fish lacking hypural plates). It may be restricted to the tip of the snout if the lower jaw projects. The base of the caudal fin (end of the vertebral column or posterior edge of the hypural plate) is determined by flexing the tail up while the caudal peduncle is held down. The resultant wrinkle or caudal flexure indicates the caudal base. It may also be determined by probing or dissection. Sometimes the posteriormost point is the last scale, the last pored scale or the beginning of the caudal fin rays. It is the usual scientific measurement for length of a fish except in Myxini, Petromyzontiformes, Elasmobranchii and Holocephali. This measurement is used because long-preserved fish often lose the tips of the caudal fin rays through breakage after the desiccation effect of alcohol. See total length and fork length. In Holocephali the length is usually taken from the tip of the snout to the origin of the upper caudal fin because the caudal filament breaks off frequently. In Scaridae it is taken back to the rear margin of the second to last lateral line scale, because the large scales obscure the point of caudal flexure. In small dead fish, the end point is detected by bending the caudal fin to one side. In fishery work, as a result of the use of the measuring board, standard-, fork- and total length are taken from the most anterior part of the head. Abbreviated as SL. (FishBase)

2) Standard length (SL) refers to the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal fin. (Wikipedia)

Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. (Wikipedia)

3) Standard length (SL) can be specified as: a) Maximum length: Size (in cm) of the largest male/unsexed or female specimen ever caught. (FishBase); b) Common length: Size (in cm) at which male/unsexed or female specimen(s) are commonly caught or marketed. (FishBase).

TotalLengthTotal length (TL)1) The greatest length of the whole body between the most anterior point of the body and the most posterior point, in a straight line, not over the curve of the body. Sometimes, when there are two equal lobes, the caudal rays are squeezed together and their tip is taken as the most posterior point (excluding the caudal filaments), or the longest lobe is squeezed to the midline (maximum length or extreme tip length). Also an imaginary line may be drawn between the two lobe tips and length to its mid-point taken as the most posterior point (total auxiliary length or bilobular length). Usually the tip of the most posterior lobe of the fin in normal position is taken as the posteriormost point (total normal length or natural tip length). Total length is used by taxonomists in Myxini, Petromyzontiformes, usually in Elasmobranchii and sometimes in other fishes. Standard length is usually employed with Teleostei. Abbreviated TL. (FishBase)


2) Total length (TL) refers to the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. (Wikipedia)

Total length measurements are used in slot limit and minimum landing size regulations. (Wikipedia)

3) Total length (TL) can be specified as:
  • Maximum length: Size (in cm) of the largest male/unsexed or female specimen ever caught. (FishBase)
  • Common length: Size (in cm) at which male/unsexed or female specimen(s) are commonly caught or marketed. (FishBase)

No lower limit is defined, but species composition changes below about 40m to 80m depth, depending on depth of the seasonal thermocline. This subzone can be subdivided into the upper circalittoral where foliose algae are present and the lower circalittoral where they are not (see Hiscock, 1985). The term is also used by Glémarec (1973) to refer to two étages of the sediment benthos below the infralittoral: a "coastal circalittoral category with a eurythermal environment of weak seasonal amplitude (less than 10°C) varying slowly" and a "circalittoral category of the open sea with a stenothermal environment" (Hiscock, 1996).Sublittoral

CITESCITESCITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) is an international agreement between governments. Its aim is to ensure that international trade in specimens of wild animals and plants does not threaten their survival. Appendices I, II and III to the Convention are lists of species afforded different levels or types of protection from over-exploitation.Species Importance To Society
CITESAppendixICITES Appendix IAppendix I lists species that are the most endangered among CITES-listed animals and plants (see Article II, paragraph 1 of the Convention). They are threatened with extinction and CITES prohibits international trade in specimens of these species except when the purpose of the import is not commercial (see Article III), for instance for scientific research. In these exceptional cases, trade may take place provided it is authorized by the granting of both an import permit and an export permit (or re-export certificate). Article VII of the Convention provides for a number of exemptions to this general prohibition.CITES
CITESAppendixIICITES Appendix IIAppendix II lists species that are not necessarily now threatened with extinction but that may become so unless trade is closely controlled. It also includes so-called "look-alike species", i.e. species whose specimens in trade look like those of species listed for conservation reasons (see Article II, paragraph 2 of the Convention). International trade in specimens of Appendix-II species may be authorized by the granting of an export permit or re-export certificate. No import permit is necessary for these species under CITES (although a permit is needed in some countries that have taken stricter measures than CITES requires). Permits or certificates should only be granted if the relevant authorities are satisfied that certain conditions are met, above all that trade will not be detrimental to the survival of the species in the wild. (See Article IV of the Convention)CITES
CITESAppendixIIICITES Appendix IIIAppendix III is a list of species included at the request of a Party that already regulates trade in the species and that needs the cooperation of other countries to prevent unsustainable or illegal exploitation (see Article II, paragraph 3, of the Convention). International trade in specimens of species listed in this Appendix is allowed only on presentation of the appropriate permits or certificates. (See Article V of the Convention)CITES

DataDeficientData Deficient (DD)A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. A taxon in this category may be well studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. Data Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate. It is important to make positive use of whatever data are available. In many cases great care should be exercised in choosing between DD and a threatened status. If the range of a taxon is suspected to be relatively circumscribed, and a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified.IUCNRedList

OSPARCommonIndicatorsOSPAR Biodiversity Common IndicatorsThe common indicators agreed by OSPAR for assessing the status of biodiversity in the North-East Atlantic cover marine mammals, seabirds, fish communities, seafloor habitats, pelagic habitats, non-indigenous species and food webs.

The biodiversity common indicators contributed assessments of the status biodiversity in the North-East Atlantic to the OSPAR Intermediate Assessment 2017. The assessments are published in the OSPAR Assessment Portal.

The indicators are based on information from monitoring programmes described in the Coordinated Environment Monitoring Programme (CEMP). The programmes are described in the Appendices to the CEMP Agreement. Detailed descriptions, including method descriptions for the indicator calculations, are included in the CEMP Guideline Agreements.

OSPARListOfThreatenedAndOrDecliningSpeciesAndHabitatsOSPAR List of Threatened and/or Declining Species and HabitatsThe OSPAR Biological Diversity and Ecosystems Strategy sets out that the OSPAR Commission will assess which species and habitats need to be protected. This OSPAR List of Threatened and/or Declining Species and Habitats has been developed to fulfil this commitment. It is based upon nominations by Contracting Parties and observers to the Commission of species and habitats that they consider to be priorities for protection.Species Importance To Society
OSPARRegionIArcticWatersOSPAR Region I: Arctic WatersRegion I is the most northerly OSPAR region, characterised by its harsh climate and ice coverage although the ecosystems of this region are still rich. In spite of its low population density, human activities such as fishing and offshore petroleum production remain significant.OSPARListOfThreatenedAndOrDecliningSpeciesAndHabitats
OSPARRegionIIGreaterNorthSeaOSPAR Region II: Greater North SeaThe Greater North Sea is one of the busiest maritime areas. Offshore activities related to the exploitation of oil and gas reserves, and maritime traffic are very important. Two of the world's largest ports are situated on the North Sea coast, and the coastal zone is used intensively for recreation.OSPARListOfThreatenedAndOrDecliningSpeciesAndHabitats
OSPARRegionIIICelticSeasOSPAR Region III: Celtic SeasThe Celtic Seas region contains wide variations in coastal topography, from fjordic sea lochs, to sand dunes, bays, estuaries and numerous sandy beaches. The large range of habitats in the region supports a diverse fish fauna. Although traditional maritime activities, such as fishing, take place in the Celtic Seas, there is ongoing development of tourism.OSPARListOfThreatenedAndOrDecliningSpeciesAndHabitats
OSPARRegionIVBayOfBiscayAndIberianCoastOSPAR Region IV: Bay of Biscay and Iberian CoastThe bottom topography of Region IV and coastlines are highly diversified, including the continental shelf and slope and parts of the abyssal plain. Ecosystems in Region IV are very rich, support a rich fish fauna and have a particular importance for migratory birds. Main human activities in Region IV are fishing, maritime transport and tourism.OSPARListOfThreatenedAndOrDecliningSpeciesAndHabitats
OSPARRegionVWiderAtlanticOSPAR Region V: Wider AtlanticRegion V represents the deep waters of the North-East Atlantic extending across the abyssal plain and the Mid-Atlantic Ridge, and including many seamounts. There have been recent discoveries of a number of different fragile deep-sea habitats (such as hydrothermal vents, carbonate mounds, coral gardens and sponge communities). Human population in the region is restricted to the Azores Archipelago. The main human activities are fishing and maritime transport.OSPARListOfThreatenedAndOrDecliningSpeciesAndHabitats
