With the rapid population growth and economic development in the river basin, fish diversity and fishery resources of this river are experiencing serious threats. Basic biological information on most fish species in the Lancang River, required to improve conservation in this area, is limited. This study aimed to provide new estimates of length-weight relationships (LWRs) by using the linear regression of W = aLb for eight indigenous fish species from the Lancang River, Southwest China. From 2018 to 2021, 534 specimens belonging to 3 families and 8 genera were collected using various types of fishing techniques. Standard length (SL) and body weight (BW) of each specimen were measured to the nearest 0.1 cm and 0.1 g, respectively. This study presents the first public records of LWR parameters of Schizothorax lissolabiatus, Poropuntius huangchuchieni, Tor sinensis, Scaphiodonichthys acanthopterus, Mystacoleucus lepturus, Hemiculterella macrolepis, Glyptothorax lampris, and Schistura porthos. The range of b values for the LWRs was 2.5378–3.1732, and the r2 values for all LWRs estimates ranged from 0.9102 to 0.9952. Intraspecific difference of b values across population and/or season was observed in S. lissolabiatus, T. sinensis, P. huangchuchieni, S. acanthopterus, and M. lepturus. The range of mean condition factor (K) and mean relative weight (Wr) was 0.97–2.39 and 100.29–108.18, respectively. This study updated information for FishBase and provided new record of maximum standard length for five species, namely, S. lissolabiatus, P. huangchuchieni, T. sinensis, S. acanthopterus, and M. lepturus.

We sampled 16 streams and captured over 14,000 individual fish among 44 species. We identified each fish to species and recorded total length (mm) and weight (g) for each individual. These data were log10 transformed and analyzed using linear regression to calculate the length-weight parameters for each species. Relationships were calculated for 44 different stream fish species. Searches in FishBase.org revealed that of the 44 species in our data, 9 species have no current data in FishBase.org (Froese and Pauly, 2016), while 20 others have no previous representation from Central Appalachia.

Currently, 50% of global fish consumption is provided by aquaculture. In India, the major cultivated fishes are Labeo catla, Labeo rohita, Cirrhinus mrigala, Hypophthalmichthys molitrix, Ctenopharyngodon idella, and Cyprinus carpio. Among these, L. rohita is a widely consumed fish. We aimed to study the effect of one of the most widely used herbicides, glyphosate, on the embryonic development of L. rohita. The 96 h LC50 of glyphosate for L. rohita embryos was found to be 20.89 mgL−1. The embryos were exposed to 1/10th, 1/5th,, and 1/3rd concentrations of LC50 for 96 h. The observed deformities included abdominal curvature, kink formation in the tail, yolk sac edema, pericardial edema, and improperly flattened swim bladder. Besides, we could observe a reduction in pigmentation at 96 h and a decrease in heart rate at 24, 48, 72, and 96 h. All these deformities led to the mortality of embryos. This study indicated that the herbicide (glyphosate) can adversely affect the natural population of the Indian major carp, L. rohita.","PeriodicalId":14894,"journal":{"name":"Journal of Applied Ichthyology","volume":"23 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134954048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
