A total of 433 specimens were collected monthly from October 2016 to November 2017, and their length, weight, sex, gonad and liver weight, and maturity status were recorded. Monthly variations in Gonado-somatic index showed two obvious peaks in the spawning period in both sexes. Observations from the seasonal maturation curve, the frequency distribution of the female gonadal development stages and the condition factor confirmed recent findings that the spawning periods have two peaks, a higher peak in April-May (spring) and a lower peak in October (autumn). The size at first maturity of females was estimated to be 38.20 cm in total length. The absolute fecundity ranged from 18072 to 332171 eggs while the relative fecundity ranged from 22 to 161 eggs/g. Absolute fecundity was positively correlated with body related parameters (total length/weight) and with gonad weight. Combined, the information provided in this study could be useful for resource managers to set seasonal closure during peak spawning periods and implement minimum size limits above the size at first maturity to let the fish spawn at least once before capture.","PeriodicalId":14599,"journal":{"name":"Iranian Journal of Ichthyology","volume":"8 1","pages":"1-13"},"PeriodicalIF":0.0,"publicationDate":"2021-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46631697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Baited Remote Underwater Video (BRUV) sampling method was applied to record the fish presence. Fishes were sampled monthly from June 2017 to April 2018 at daylight time (9:00 to 14:00) during high tide. Water temperature, turbidity, and salinity were recorded at the time of sampling. During the study, a total of 17 species belonging to 12 families were identified. A mbassis gymnocephalus was found as the dominant fish throughout the year except in November and December. The most abundant fish fauna in numbers was characterized by the following five species: Ambassis gymnocephalus (53.38%), Sardinella sp. (17.13%), Terapon jarbua (4.79%), Rhabdosargus sarba (3.25%) and Acanthopagrus berda (2.9%). ANOSIM showed that significant differences in the assemblage structure occurred among months (R=0.613, P < 0.001), and the CLUSTER analysis, together with the SIMPROF test showed that December is significantly different in term of fish assemblage. Canonical Correspondence Analysis (CCA) on species-environment correlations revealed that temperature and turbidity were the main parameters influencing fish occurrence in the mangrove habitat of Chabahar Bay. The overall diversity (Shannon–Wiener, Simpson’s Index of Diversity, and Pielou’s evenness), as well as functional diversity indexes (FRic and FDis), was higher in autumn and spring pointing out that the diversity is higher when the temperature had the closest value to averaged value.","PeriodicalId":14599,"journal":{"name":"Iranian Journal of Ichthyology","volume":"7 1","pages":"338-351"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68013489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The endangered mahseer, Tor putitora (Hamilton, 1822) is a commercially important fish distributed extensively in the foothills of Himalayas. Box plots and multivariate statistical tools like Principal Component Analysis (PCA) and Discriminant Function Analysis (DFA) were used to delineate the stocks of T. putitora from two Indian rivers, Yamuna and Satluj using 6 meristic and 24 morphometric characteristics. A comparison of the morphometric and meristic characters using box plots revealed variations in eye diameter (ED), length of rostral barbel (LRB), standard length (SL), pre-anal distance (PAD), distance between pectoral and pelvic fin (DPP), distance between pelvic and anal fin (DPA), length of dorsal fin (LDF), length of pectoral fin (LpecF), length of pelvic fin (LpecF) and length of caudal fin (LCF) for distinguishing populations from these two rivers. Upon PCA, the first three principal components accounted for 69.66% of total variance in head parameters whereas for total length, the first 5 principal components accounted for 73.23% of total variance. For meristic characters, the first two PCs explained 75.65% of the total variance. The step-wise DFA retained only one function for morphometric as well as meristic characters explaining 100% of the variance. The Wilks’ lambda tests for morphometric and meristic data indicated differences between the populations of T. putitora from both the rivers.","PeriodicalId":14599,"journal":{"name":"Iranian Journal of Ichthyology","volume":"7 1","pages":"323-337"},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45300136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The olfactory organ holded 16 pairs of lamellae emitted from central raphe, consummate an oviform rosette. The multilamellar olfactory rosette was distinctively placed on the ground of nasal cavity and differentiated by specialized sensory and non-sensory territory. Sensory epithelium covered apical part and linguiform process of lamella while rest part is disguised by non-sensory epithelium. The sensory epithelium had two specific forms: ciliated receptor cells and microvillous receptor cells categorized by staining magnitude, texture and surface morphology. In divergence, the nonsensory epithelium was made up of stratified epithelial cells with microridges, cluster of ciliated non-sensory cells and secretory mucous cells. Basal cells were buried in the mucosa, presumed to be the progenitor of sensory or other supporting cells. Functional implication of cellular components on the olfactory lining was argued with feeding habits and behaviour of fish interested.","PeriodicalId":14599,"journal":{"name":"Iranian Journal of Ichthyology","volume":"7 1","pages":"306-313"},"PeriodicalIF":0.0,"publicationDate":"2020-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47130097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
