Note: For diameter you can specify the measurement type (minimum, maximum, average), gender (male, female) and life stage., URL"URL" is a type and predefined property provided by Semantic MediaWiki to represent URI/URL values.: http://www.marinespecies.org/traits/wiki/Traits:Diameter)

          • TaxonSpecificBodySizeFish (Definition: Fish measurement is the measuring of the length of individual fish and of various parts of their anatomy. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. (Wikipedia), URL"URL" is a type and predefined property provided by Semantic MediaWiki to represent URI/URL values.: http://www.marinespecies.org/traits/wiki/Traits:TaxonSpecificBodySizeFish)
            • ForkLength (Definition: 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)
  • Common length: Size (in cm) at which male/unsexed or female specimen(s) are commonly caught or marketed. (FishBase)
, URL"URL" is a type and predefined property provided by Semantic MediaWiki to represent URI/URL values.: http://www.marinespecies.org/traits/wiki/Traits:ForkLength)
            • StandardLength (Definition: 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)., URL"URL" is a type and predefined property provided by Semantic MediaWiki to represent URI/URL values.: http://www.marinespecies.org/traits/wiki/Traits:StandardLength)

            • TotalLength (Definition: 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)

Note: For width you can specify the measurement type (minimum, maximum, average), gender (male, female) and life stage., URL"URL" is a type and predefined property provided by Semantic MediaWiki to represent URI/URL values.: http://www.marinespecies.org/traits/wiki/Traits:Width)

          • Wingspan (Definition: In birds (Aves) - "the distance between the wing tips when the wings are held outstretched" (Wikipedia) or "wingtip to wingtip in flight" (BTO).

In winged insects (Insecta) - "may refer to the distance between the centre of the thorax to the apex of the wing doubled or to the width between the apices with the wings set with the trailing wing edge perpendicular to the body" (Wikipedia)

Appendices I, II and III to the Convention are lists of species afforded different levels or types of protection from over-exploitation., URL"URL" is a type and predefined property provided by Semantic MediaWiki to represent URI/URL values.: http://www.marinespecies.org/traits/wiki/Traits:CITES)

      • CITESAppendixI (Definition: Appendix 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., URL"URL" is a type and predefined property provided by Semantic MediaWiki to represent URI/URL values.: http://www.marinespecies.org/traits/wiki/Traits:CITESAppendixI)
      • CITESAppendixII (Definition: Appendix 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), URL"URL" is a type and predefined property provided by Semantic MediaWiki to represent URI/URL values.: http://www.marinespecies.org/traits/wiki/Traits:CITESAppendixII)
      • CITESAppendixIII (Definition: Appendix 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.
