Gentamicin is known to stimulate the production of reactive oxygen species and lead to renal damage in some groups of vertebrates through oxidative stress. The kidney regeneration of the killifish Aphanius furcatus was studied after gentamicin-induced oxidative stress. In addition, we evaluated the possible role of vitamin C as an antioxidant in the reduction of renal toxicity. A total of 24 specimens (3.5-4cm in total length) were divided into four groups: In group-I two fish specimens treated with 7.5µl of normal saline injection; in group-II, 10 specimens received 10µg/g body weight (b.w) gentamicin; in group-III, two fish were treated with totally 60µg/g b.w vitamin C; and in group-IV, 10 specimens received both 10µg/g gentamicin and 60µg/g b.w vitamin C. The kidney tissues of group-I, III and IV were sampled during the nephrotoxicity phase (i.e., 10 hours post injection (hpi) to 5 days post injection (dpi)) and kidney tissues of group-II sampled daily for 10 dpi until regeneration completed. The kidney regeneration of A. furcatus through nephron neogenesis was detected by newly formed nephron on 8 dpi, and it is completed on 10 dpi. Our histological results in gentamicin-induced oxidative stress (group-II) clearly showed that the most severe damage is occurred in the kidney tissue within 1-4 dpi. However, in the specimens that antioxidant therapy supplied with vitamin C (group-IV), damage effect of gentamicin has remarkably repressed within these days. The outcome of this study revealed that administration of vitamin C is effective in reduction of gentamicin-induced nephrotoxicity in A. furcatus . Vitamin C reduces the toxicity effect of gentamicin by reduction of free radicals and reactive oxygen species (ROS) through its antioxidant activity. Therefore, using vitamin C together with gentamicin enhances the body resistance to the stress condition and reduces the toxicity effect of gentamicin.

In Indian freshwater aquaculture, which largely depends on carps, diseases have become a major problem. This study evaluated the health status of Catla catla, Labeo rohita, Cirrhinus mrigala and Labeo bata cultured in West Bengal, India by determining the Health Assessment Index (HAI) and coefficient of variation (CV) of HAI values of each species as well as the superoxide anion production. The annual mean HAI value was the highest for L. rohita (77.51) and least for L. bata (55.30). The highest and lowest CV of HAI values were recorded for L. bata (95.80) and C. mrigala (52.55), respectively . The HAI values correlated negatively ( P <0.05) with temperature. The HAI distinguished successfully among the species, seasons and sampling areas on the grounds of temperature and water quality, with higher index values recorded in carps grown in poorly managed ponds. Labeo bata exhibited higher immune responsiveness compared to other carps. Labeo rohita was the most susceptible to diseases. The results on the high production of oxygen radicals by phagocytic cells of L. bata together with low HAI and high CV values suggested that this species may resist biotic and abiotic stressors well under culture conditions. The results suggested that HAI and superoxide anion production can be used to assess the health status of carps under the culture conditions.

Otolith morphology is important for species identification, fishery management and stock assessment. In this study, otolith (Sagitta) morphology of four fish species viz. Pomatomus saltatrix , Sarpa salpa , Trachurus trachurus , and Belone belone was investigated. The length (mm), width (mm), area (mm 2 ) and perimeter (mm) measurements of the otoliths were made and four different shape indices, including form factor (F F ), aspect ratio (A R ), roundness (R D ) and circularity (C I ) were calculated. In addition, relationships between total fish length and otolith morphology were investigated. Measurements of sagittal otoliths of four species were obtained by image analysis using tri-ocular microscope. Based on the results, the morphometric measurements and four examined shape factors of otolith varied among species. Coefficients of correlations (r) between total fish length and otolith morphology and otolith length-otolith morphology were generally highly significant ( P <0.05) for studied fishes. The results show that the shape indices were significantly different in analyzed species even they indicated a similar pattern with maximal otolith length. These data provide information for species identification using sagittal otoliths in the fossils and diets of fish predators and also will contribute to the region's sustainable fisheries management.

This study was carried out to determine the intra- and inter- population variations of chub, Squalius cephalus , utricular and lagenar otolith shapes sampled from four localities in the Black Sea region. Otolith shape indices, including Form Factor (FF), Circularity (C), Roundness (RO), Rectangularity (RE), Aspect Ratio (AR) and Ellipticity (E) were used for otolith shape analyses and multivariate analyzes (Canonical Discriminant Analysis) were used to assess interspecies variations. The FF and C were found statistically significant for lapillus, but not for asteriscus otoliths in the four habitats. Furthermore, RO was similar for all localities for both asteriscus and lapillus. CDA results showed that 66.5% of the chub individuals were correctly classified. The results indicated otolith shape can be used as a suitable tool to discriminate chub populations.

Some aspects of reproductive biology of Capoeta razii , an endemic cyprinid species from the Sefid River in the southern Caspian Sea basin, were studied by monthly sampling throughout a year. Age, growth, sex ratio, spawning season, fecundity, gonado-somatic, modified gonado-somatic and Dobriyal indices were estimated. The sex ratio (F: M) was obtained as 1.00:2.63, and the percentage of males was greater than females. The mature males and females were longer than 88 and 148 mm in total length, and 1 + and 2 + in age, respectively. The spawning of C. razii took place from late May to late August when the water temperature was between 19.7 and 22.8 ◦ C. At the beginning of the reproduction period, the average gonado-somatic index values were 10.0% ranging from 4.03% to 15.90% in ripe females. The estimated gonadal indices showed that the ripe males were ready to spawn earlier than females. The average egg diameter was 0.99±0.65, ranging from 0.2 to 2.3 mm. The averages absolute and relative fecundity were 4386±2174 and 66.3±37.8, respectively. The absolute fecundity was significantly related to body weight and gonad weight.

The Iranian species of the genus Sabanejewia are reviewed based on morphological, osteological and molecular characters of the mtDNA COI barcode region. Two species, Sabanejewia aurata and Sabanejewia caspia are recognized and diagnoses are presented for both species. They are distinguishable through body pattern, length of caudal peduncle, snout and post orbital distance, shape of scale and suborbital spine, caudal complex skeleton and also the number of fixed, diagnostic nucleotide substitutions. Here we re-describe both Iranian spined loaches.

The monospecific genus Allips is reported here for the first time from Indian waters, from a specimen collected from the sea grass bed outside the Nalban bird Sanctuary, Chilika lagoon, India, with its morphometric characters, vertebrae and teeth pattern. The rare small eye snake eel A. concolor was earlier described by McCosker, 1972 on the basis of a single specimen. After that, there are very rare reports on this particular species especially on its morphometry after McCosker (1972). This paper extends the range of A. concolor McCosker, 1972 from eastern Andaman Sea and Northern Territory, Australia to Indian waters. A detailed discussion on the distribution and habitat is also provided in this paper.

A new species of nemacheilid fish, Oxynoemacheilus veyseli sp. n., is described from the upper Aras River drainage, Kars Province, Turkey. The species differs from its congeners in the Caspian Sea basin in the combination of the following characters: flank with a set of mid-lateral elongated, irregular-shaped dark brown blotches, sometimes fused, interrupted by lateral line; dorsum with three or four separated dark-brown roundish to elongated blotches predorsally and postdorsally; a deep and marked suborbital groove and many small unculi on rays of pectoral and dorsal-fin in male; small eye diameter (9.6-13.7 %HL); a short dorsal-fin base (10.1-13.3 %SL); 3-4 lateral and 3 central pores in supratemporal canal; deep body and caudal peduncle (17.3-19.4 and 10.2-11.4 %SL, respectively) and slightly emarginated caudal fin.
