Length–weight relationships (LWR) were estimated for 17 species and total length at first maturity (L50) for three species of freshwater fishes from the Miranda River, southern Pantanal, Brazil. The b values were compared for some species in the Paraguay River basin with the northern (Cuiabá River) part of the basin; differences in length–weight relationships were significantly different for Pseudoplatystoma corruscans, P. reticulatum (syn. P. fasciatum). First references on L50 and LWR are presented for two and eight fish species, respectively, as well as the new maximum total length for two species. 相似文献

Length–weight (LWR) and length–length (LLR) relationships was estimated for three fish species collected in Chahnimeh reservoirs located in the city of Zabol, Iran. The values of the parameter slope (b) in the length–weight relationship were determined 2.45 for Crossocheilus latius, 2.97 for Schizocypris altidorsalis and 3.14 for Schizothorax zarudnyi. The relationships between TL, FL and SL were all linear (for all cases: r2 > 0.93). 相似文献

This paper provides the length–weight relationships of three fish species from the middle and lower reaches of the Jinsha River, China. Samples were obtained seasonally during 2013~2016 using fishing gear (drift gillnets and di long) and electroshock fishing techniques (backpack electrofishing control unit powered by 12 V). For each species, the sample size, length range, weight range, LWR, 95% confidence intervals of a and b, and coefficient of correlation were determined. Length–weight relationship (LWR) for one species was unknown to FishBase and new maximum lengths were recorded for two species. 相似文献

Length–weight relationships (LWR) were estimated for 34 fish species belonging to 25 genera and 17 families, specimens were collected near the mouth of the Río Verde, Oaxaca, Mexico. All r2 values are statistically significant (P > 0.0001). The values of ‘b’ ranged from 2.55 and 3.3, within the usual range (2.5–3.5). This study provides the first LWR references for six species, and new maximum length records for eight species. 相似文献

Length–weight relationships (LWR) are presented for 27 freshwater fish species representing 11 families captured in the Trombetas River, a clearwater left margin tributary of the Amazon River. The allometry coefficient (b) of the LWR (W = aTLb) ranged from 2.51 to 3.49, with a median value of 3.00. This study represents the first reference on LWR for 23 species and new records of maximum lengths for 15 species. 相似文献

This study describes the length–weight and length–length relationships for three cyprinid species from the Bibi‐Sayyedan River (western Isfahan provinces, Iran). The slope parameter (b) values in the length–weight relationship equations were determined as 3.0729 for Alburnus mossulensis Heckel, 1843; 2.8509 for Barbus lacerta Heckel, 1843; and 3.0864 for Chondrostoma regium (Heckel, 1843). This study presents the first LWR and LLR references for these species in the Bibi‐Sayyedan River. 相似文献

The length‐weight relationships or LWR (W = aLb) of 18 of the 21 fish species caught in 2007–2008 from the Candaba wetland in central Luzon, Philippines are reported. These species belong to 14 families and the LWR of six species are first documented in this paper. Cyprinids comprised the greatest number of species. The high significance of the LWR parameters indicate that fish weight may be predicted from length, at least within the range of the fish lengths recorded. This first reference to the LWR of fishes from the Candaba wetland provides baseline data for the conservation management of fish biota in this threatened ecological resource. 相似文献

Length–weight relationships (LWR) were estimated for seven fish species inhabiting the intertidal mudflats in the Marajó Bay, northern Brazil. A total of 514 specimens were collected quarterly between November 1994 and December 1995 using a beach seine (5 mm mesh size between opposite knots). Slope b of the LWR varied between 2.93 and 3.11, with a mean of 3.02. This study represents the first reference on LWRs for seven species and a new maximum length record for one of these species. 相似文献

Length–weight relationships (LWR) and length–length relationships (LLR) were estimated for four species, namely, Puntius sophore (Hamilton, 1822), Puntius chola (Hamilton, 1822), Pethia ornatus (Vishwanath & Laisram, 2004) and Pethia ticto (Hamilton, 1822) collected from different wetlands of Lakhimpur, Assam. The values of the parameter slope (b) in the LWR were 3.30 for Puntius sophore, 3.22 for Puntius chola, 2.61 for Pethia ornatus and 3.27 for Pethia ticto. The relationships among TL, FL and SL were all linear (r2 > 0.95). 相似文献

This study reports the length–weight relationship (LWR) and length‐length relationship (LLR) estimated for four fish species inhabiting in Chilika Lake, India. Total 504 specimens were sampled from mono‐filament gill nets (mesh size 12 mm, 22–24 mm, 34–38 mm, 42 mm) during January 2015 to December 2015. The estimated b values from LWR ranged between 2.79 (T. biaculeatus) to 3.29 (C. praeustus). In all species, the relationships between length‐weight and length‐length were highly correlated (p < .05). The study provides first world reports on LWRs and LLRs for all the 4 studied species. 相似文献

Length–weight relationships (LWR) for five Gobiidae species collected by trawl net in Bohai Bay, China, were determined. Parameter b in the LWR was 2.871, 2.664, 2.901, 3.237 and 2.882 for Amblychaeturichthys hexanema, Synechogobius ommaturus, Odontamblyopus rubicundus, Tridentiger barbatus and Paratrypauchen microcephalus, respectively. This is the first report in FishBase for the fitted LWRs of three of the Gobiidae species mentioned above. 相似文献

The present study provides the length–weight and length–length relationships information (LWR & LLR) for three Blenny species; Antennablennius adenensis from the coast of Larak Island in the Persian Gulf and Istiblennius pox and Omobranchus mekranensis, which were captured in the coasts of Chabahar city in the Gulf of Oman, Iran. Total length (TL) and standard length (SL) were determined as well as weight. Specimens were collected occasionally in summer 2017 and winter 2018 by Hand net. The length–weight parameter b for these species was 2.84, 3.29 and 3.06 respectively with a high coefficient of determination (r2 ≥ 0.95). All LLRs were highly correlated (r2 > 0.99). All three species had no previous report for LWR and LLR estimates in FishBase. 相似文献

The paper reports the length–weight relationships of 3 species from the Poyang Lake, the largest freshwater lake freely connect to the Yangtze River, China. A total of 1,207 specimens were collected seasonally (January, April, September and November, 2010) using various types of fishing gear nets (mesh size: 1–12 cm) and stationary lift nets (mesh size: 0.7–4.4 cm). For each species, the sample size, length range, weight range, LWR, 95% confidence intervals of a and b, and coefficient of correlation were determined. Length‐weight relationships for 1 species were unknown to FishBase, and new maximum lengths are recorded for 2 species. 相似文献

Length–weight (LWR) relationships were estimated for nine fish species collected in the Wujiang River located near the city of Chongqing, China. The value of the exponent ‘b’ in the LWR was between 2.594 and 3.528, which shows that the species exhibit an allometric growth pattern. All relationships between total length (TL) and body weight (BW) were linear (in all cases: r2 > 0.913). 相似文献

Length–weight relationships (LWRs) are presented for 11 deep‐sea fishes caught in the western Bay of Bengal and Andaman waters during August 2010 using a 38 m high speed demersal trawl II (HSDT II, crustacean version, codend mesh size 40 mm) and a 45.6 m Expo model demersal trawl (codend mesh size 30 mm). The b values ranged from 2.34 to 3.3 and the coefficient of variation (r2) ranged from .82 to .98. LWR estimates of eight deep‐sea fishes are provided for the first time. The estimated LWR values were compared with the Bayesian LWR estimates available in FishBase, based on models developed to improve the accuracy and predictability of species‐specific growth parameters of data‐poor species. 相似文献
