“…In addition, the comparison of length-weight relationship parameters obtained by various researchers from different regions for other fish species belonging to the genus Cobitis and Oxynamecheilus are given in Table 4 and Table 5. Based on previously reported studies, positive allometry (+) and negative allometry (-) were observed in O. hamvii from Turkey (Table 3). Positive allometric growth (b= 3.520) determined in this study was in accordance with results reported in the previous study (Özcan & Altun, 2016). On the contrary, Birecikligil & Ciçek (2011) from Euphrates and Orontes Rivers of Turkey has reported negative allometric growth (b= 2.660).…”

The length-weight relationships (LWRs) are one of the most useful parameters for fishery management and have importance in fisheries science. The present study describes the lengthweight relationships for four freshwater fish species from the Asi River system (Hatay, Turkey), namely Cobitis anabelae Freyhof, Bayçelebi & Geiger, 2018, Cobitis levantina Krupp & Moubayed, 1992, Oxynamecheilus hamvii (Krupp & Schneider, 1991 and Oxynamecheilus namiri (Krupp & Schneider, 1991). A total of 154 specimens collected for this study was caught by fishing gears from June 2017 and March 2018. This study presented the first reference on LWRs for C. anabelae, C. levantina, and O. namiri from inland waters of Turkey. Besides, this data also will be helpful in FishBase.

“…Allometric growth of Oxynoemacheilus genus determined in this study was in accordance with results reported in earlier studies (Gaygusuz et al, 2012;Erk'akan et al, 2013;Erk'akan et al, 2014;Innal et al, 2015;Birekcikligil et al, 2016;Özcan & Altun, 2016).…”

“…The total length of O. anatolicus ranged from 2.5 to 8.6 cm, which fits well within the known values (Table 3) while the minimum length observed in this study was close to the value reported for Oxynoemacheilus angorae from the Kızılırmak River Basin (Birekcikliğil et al, 2016). The maximum length was closer to known reported values for some species; Oxynoemacheilus angorae from the Kızılırmak River Basin (Birekcikliğil et al, 2016) and Sögütözü Beynam (Erk'akan et al, 2014), for Oxynoemacheilus hamwii from Gölbaşı Lake (Özcan & Altun, 2016), for Oxynoemacheilus mesudae from Küfe Creek (Erk'akan et al, 2014), for Oxynoemacheilus samanticus from Karaboğaz Creek (Erk'akan et al, 2014), for Oxynoemacheilus theophilii from Yiğitler Creek (Innal et al, 2015). In population structure, female individuals of O. anatolicus showed wider length range, mean length and weight than males.…”

“…Despite the high diversity and endemism of Oxynoemacheilus genus in Turkey, knowledge about its biology and population dynamics are still limited. Most of the available studies have focused mainly on lengthweight relationships (Gaygusuz et al, 2012;Erk'akan, Innal, & Özdemir, 2013, 2014Innal, Özdemir, & Dogangil, 2015;Birecikligil, Çiçek, Öztürk, Seçer, & Celepoğlu, 2016;Özcan & Altun, 2016;Yazıcıoğlu & Yazıcı, 2016).…”

The present study reports the age and growth properties of Burdur Loach, Oxynoemacheilus anatolicus Erk'akan, Özeren & Nalbant, 2008 caught from the Düger Spring Creek (Burdur-Turkey) and is currently listed as an endangered species. 100 specimens of O. anatolicus, which ranged in size between 2.5 and 8.6 cm in total length, 0.14 and 5.90 g in total weight, were collected during the study period. Of all the O. anatolicus examined, 5 were immature, 50 were female, and 45 were male. The overall sex ratio in the populations matches the expected value of 1:1 in a normal population. The otolith readings indicated the presence of five age classes (I-V). Length-weight relationships were fitted by the equation W= 0.0082L 3.0402 (p<0.05) for both sexes combined and this indicated that growth was positive allometric. The condition factor values were calculated and ranged from 0.64 to 1.19. The obtained data was compared with available results from close species. This study provided first baseline data related to length-weight relationship, age, sex ratio and condition factor for O. anatolicus -a species whose populations have been threatened due to various ecological changes in its habitats, leading to increased concern and the need for conservation.

“…The length-weight relationships (LWRs) were determined by the method of least squares using the equation W = aL b (Wang et al, 2012), where "W" was the weight of the samples in gram and "L" the length of the samples in centimeter, "a" parameter is the intercept and "b" parameter is the slope.…”

The understanding of the distribution and population structure of the various species in the marine environment is very helpful to effectual resource management and conservation. This study aimed to assess ecological factors relating to sea cucumber populations on the rocky shores of the Persian Gulf. Population of two species of sea cucumber were investigated along 6 intertidal rocky sites, including Deylam, Bushehr, Dayer, Nayband, Bostaneh, and Lengeh in Bushehr and Hormozgan Provinces. During the period of the sampling, no sea cucumbers were observed in Deylam and Lengeh stations. To address this, 500 individuals of sea cucumber were collected and transported from their natural habitat to the laboratory. During the whole study, two species were observed (Holothuria parva and Holothuria arenicola). The Highest abundance were obtained at the stations of Dayer (198 individuals) and Bostaneh (188 individuals). The maximum density (individuals per 200 m 2 ) was estimated for Dayer (49.5 ± 6.13) and Bostaneh (47 ± 8.79). The results of the study revealed a negative allometric growth for both species. The results showed that different ecological indices of sea cucumbers community in the study areas affected by physicochemical parameters such as pH, temperature, salinity and possibly lack of correct management in order to enforce more protective approaches relating to these animals.
