Abstract

Ovigerous females (41 specimens) from Glyphocrangon alata, captured between Iquique and Arica allowed to extend to the latitudinal and bathymetric distribution of the species. Relations carapace length/carapace width and carapace length/total length are linear at all morphological ranges. Carapace length and total varied between 21.9-33.1 and 68.5-103.3 mm, respectively. A fecundity relation is described by a linear regression of carapace length/carapace volume for a range of 17 to 179 eggs; fresh-laid egg volume: 15.68 mm3. The eggs being big size and few characterize the species as having a low fecundity and a direct embryonic development. A reproductive output of 0.118, based on wet weight values was calculated; it stands near the caridean shrimp values from polar and temperate regions. The study was derived from a report project from the United Nations Development Programme (UNDP).
