“…The size of the oil droplets may change in individuals based on genetics and age of the embryo (Cunningham & Balon, ). These results confirm the hypothesis of the response of killifish to local selective pressures in different habitats through adaptations via changes in the duration of the reproductive period and egg diameter (Kamal et al., ).…”

“…Based on the data of Kamal, Bakhtiyari, Abdoli, Eagderi, and Karami (), average diameter of mature eggs of A. sophiae from Shour River (Namak Lake basin) was 1.401 ± 0.19 mm with minimum and maximum diameters of 0.66 and 2.23 respectively. According to Sezen and Olmez () the eggs of A. mento are spherical, transparent and sticky, and full of egg yolks with 7–8 oil droplets, having adhesion filaments on the surface with average diameter of 1.589 ± 0.50 mm.…”

Summary Understanding embryonic development and ontogeny of species is a crucial part of any further biology, ecology and conservation studies. The present study describes the first detailed normal embryonic development of a tooth‐carp, Aphanius sophiae (Heckel, 1847), from fertilization to post‐ hatching. Aphanius sophiae spontaneously spawned at 24 ± 1°C. The newly laid eggs were transparent and spherical (1.45 ± 0.20 mm). We documented developmental times at 24 ± 1°C to egg activation (0.5 hr), cleavage (3 hr), blastula (10 hr), gastrula (20 hr), neurula (24 hr), somite (28 hr), turnover (60 hr), blood circulation (70 hr) and hatching (330 hr). This study contributes to a further understanding of the embryology and the early ontogeny of A. sophiae and may help improve the culture of other threatened species of the genus Aphanius.

“…For A. fasciatus from Mesolongi and Etolikon lagoons, the values were calculated as 94.44 mm and 79.22 mm for females and males, respectively (Leonardos and Sinis, 1999). Seasonal change in GSI values indicates an extended spawning period; this strategy has also been found in many other studies (Ferna´ndez-Delgado et al, 1988;Garcia-Berthou and Moreno-Ami, 1992;Leonardos and Sinis, 1998;Keivany and Soofiany, 2004;Kamal et al, 2009;Gu¨c¸lu¨and Ku¨c¸u¨k, 2011). It has been stated that L ∞ increased in length with the decline of the temperature (Basilone et al, 2004).…”

Summary The life‐history traits of Aphanius danfordii in Hirfanlı Reservoir were studied on the basis of 2252 specimens caught between April 2008 and April 2009. Maximum age was determined as five years for both sexes. The overall sex ratio of males to females was 1 : 1.21; however, this ratio varied by age and season. Mean total length at age data derived from scale readings were used to estimate growth. The von Bertalanffy growth parameters were: L∞ = 126.63 mm, K = −0.09, t0 = 2.35 for females; and L∞ = 61.2 mm, K = −0.19, t0 = 2.76 for males. The gonadosomatic index (GSI) values indicated spawning to be from May to September. Absolute fecundity varied from a minimum of 143 eggs for age one to a maximum of 698 eggs for age five. Relationships between fecundity–length and fecundity–weight were described by the equations: F = 0.0002 TL3.3222 and F = 36.032 W1.0053, respectively. The equation of the relation between absolute fecundity and age was F = 25.372 t1.2343.

“…They were commonly identified as Aphanius sophiae (Heckel, 1849) (Coad and Abdoli 2000; Kamal et al 2009); however, it was shown that the true Aphanius sophiae is restricted to the endorheic Kor River basin near Shiraz (Fars Province) (Coad 2009; Esmaeili et al 2012). This study describes a newly discovered Aphanius population from the Namak Lake basin in northern central Iran (Fig.…”

A new species of tooth-carp, Aphanius arakensis sp. n., is described from the Namak Lake basin in Iran. The new species is distinguished by the congeners distributed in Iran by the following combination of characters: 10–12 anal fin rays, 28–32 lateral line scales, 10–13 caudal peduncle scales, 8–10 gill rakers, 12–19, commonly 15–16, clearly defined flank bars in males, a more prominent pigmentation along the flank added by relatively big blotches in the middle and posterior flank segments in females, a short but high antirostrum of the otolith that has a wide excisura, and a ventral rim with some small, drop-like processes, and 19 molecular apomorphies (17 transitions, two transversions) in the cytochrome b gene. It was suggested based on the phylogenetic analysis that the new species is sister to Aphanius sophiae from the Kor River and that Aphanius farsicus from the Maharlu Lake basin is sister to Aphanius arakensis plus Aphanius sophiae. A noticeable feature of the Aphanius diversity in Iran is the conservatism of the external morphology as well as morphometric and meristic characters, while distinctive differences are present in genetic characters, otolith morphology, and male color pattern. Transformation of the latter was probably driven by sexual selection.
