Gadidae (cod, haddock; superorder Paracanthopterygii, order Gadiformes) A family of marine fish found in cold to temperate waters. All members of the family have spineless fins. Some species have three dorsal and two anal fins. Typically, the pelvic fins are located far forward, ahead of the pectorals and include more than five soft fin rays. Usually there is a single barbel on the chin. Several species are of considerable commercial importance (e.g. the European Gadus morrhua (cod), which was already an important staple product to the Scandinavian Vikings). The omnivorous cod is a prolific species: large (10 kg) females may release some four million eggs. Other important species include Melanogrammus aeglefinus (haddock), Molva molva (ling), and Lota lota (burbot), a freshwater representative. There are about 55 species, occurring in the northern Atlantic and Pacific.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
