    Journal of Applied Ichthyology – early view

    Abstract

    The current study aims to update the range of Aphanius fasciatus occurring in inland aquatic systems, and to characterise the length–weight relationship of specimens caught in inland waters of the Northern Sahara of Algeria. Although the known distribution of Afasciatusis restricted to coastal waters including islands of the Mediterranean region, visits to 39 hydrosystems in Northeast Algeria revealed the presence of the species at two sites: Oued Still and Lake Temacine. Both sites are in the Sahara Desert of Algeria, where the climate is hot and hyperarid. The surveyed populations perform their entire life cycle at the same sites. Analysis of a sample composed of 27 individuals captured in Oued Still allowed determination of the length–weight relationship. On average, females measured 4.2 ± 0.6 cm in length and weighed 1.1 ± 0.5 g; males were 3.2 ± 0.6 cm and 0.5 ± 0.2 g. Growth parameters of the von Bertalanffy equation for Afasciatus were estimated at Lt = 5.5145 (1−exp (−0.341(t−0.0049))), Wt = 2.6692 (1−exp (−0.271t))3.
