Abstract

The invertebrate by-catch of the Argentinean squid Illex argentinus collected by bottom trawls off San Jorge Gulf during an expedition performed in December 2020 was employed to characterize the bottom assemblages of the area, with special emphasis on sponges. According to the results, sponges were conspicuous and abundant components in these benthic communities, representing up to 40% of the total invertebrate by-catch (average: ~130 kg·nm2 per site). Tedania (T.) mucosa was the dominant species. Other recorded species were T. (T.) charcoti, T. (T.) murdochi, Isodictya verrucosa, Iophon proximum, Clathria (C.) microxa, C. (C.) discreta, Haliclona bilamellata, Siphonochalina fortis, and Myxilla (M.) mollis. The results of this study contribute to filling in the gaps in the distribution records of sponges in the continental shelf of Argentina in a previously poorly studied area.
