Report on the Danish Oceanographical expeditions 1908-1910 to the Mediterranean and adjacent seas. Vol II Biology. A.8 Lepadogaster By Frederic Guitel (1919)

This is a historical dataset that forms part of the Report on the Danish Oceanographical Expeditions 1908-1910 to the Mediterranean and adjacent seas. It includes data for the fish of the genus Lepadogaster sampled from several sites of the North Atlantic Ocean, near the English and French coasts and the Strait of Gibraltar during the years 1904-1910. The infromation extraction was based on the Table 1 of the publication and included abundance data and metadata of location, date, depth and the sampling effort. Additional information, such as the life stage, was extracted from the main text of the publication. The dataset was curated by the citizen scientists of the Zooniverse platform within the efforts of incorporating citizen science in the management of historical datasets of EMODnet Biology project. Standard quality control steps followed after this process. Sampling Methods - The sampling instrument was a Petersen surface trawl. It was provided with several lengths of cable thrown into the sea so the depth of the sampling varied according to this length.

Taxonomic Coverage - The dataset regards the Lepadogaster genus. In the original publication it is stated: "It is certain that they all belong to the group of Lepadogaster with short dorsal and fins, i.e. with less than nine rays (L. bimaculatus and microcephalus) but the alteration of pigmentation and the lack of data on the embryonic characteristics of the two species prevent us for the moment from going further." Two individuals of the species Lepadogaster candolii Risso, 1810 are also reported but they are not included in the Table 1 of the publication so they were not included in the dataset.
