Length–weight relationships of fishes from western Caribbean freshwater drainages of Venezuela

This report describes the length–weight relationships (LWRs) of 22 freshwater fish species from freshwater western Caribbean drainages in Venezuela. Fishes were collected in dry seasons between 2005 and 2007 with standardized electrofishing from coastal streams of Aroa, Yaracuy and Urama drainages. Results include the first LWR information for ten endemic and threatened species. Novel data on these freshwater fish faunas are important for monitoring their populations, as well as the condition of fluvial habitats to promote strategies for their conservation.

Length‐weight relationships for six freshwater fish species from the Seyhan Reservoir (south‐eastern Anatolia,Turkey)

Length–weight relationships (LWRs) were evaluated for six freshwater species from the Seyhan Reservoir (south‐eastern Anatolia, Turkey): Alburnus orontis, Capoeta angorae, Capoeta erhani, Garra rufa, Luciobarbus pectoralis and Salaria fluviatilis. A total of 525 specimens were captured from five locations using gill nets, scoop nets, and trammel nets of various mesh sizes in November 2012, March 2013 and September 2013. Regressions of all species were found to be significant. These are the first LWR reports for these species from the Seyhan River basin, and the first LWR reports for three of these species (Alburnus orontis, Garra rufa, Luciobarbus pectoralis) from inland waters of Turkey.     

Length–weight relationships of nine freshwater fishes from six rivers of the Western Ghats of India

Length–weight relationships (LWRs) were estimated for nine freshwater fish species collected three times using a scoop net (mesh size 0.3–0.5 cm), cast net (mesh size 1–1.5 cm) and gillnet (mesh size 2.5–4.5 cm) from six rivers of the Western Ghats of India during August 2017–October 2018. The b values for LWRs varied from 2.862 to 3.656 (R² > 0.916 and p < 0.0001 for all species).

Length–weight and length–length relationships of three cyprinid fishes from the Bibi‐Sayyedan River,western Iran

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).

Fish samples were collected quarterly using scoop‐nets (5 mm mesh size), casting nets (7 mm mesh size) from 2017 to 2018. For LWRs using the general equation from Froese (2006), the parameter b ranges from 3.14 (Oryzias latipes) to 3.37 (Iksookimia longicorpa). LWRs data of these two species have not yet been listed in FishBase.

Length–weight relationships for estuarine fishes in South Brazil

The present study reports the length‐weight relationships (LWRs) for 18 estuarine species sampled in Guaratuba Bay, South Brazil. For the majority of these 18 species the LWRs are known from the literature, but these estimates do not consider sexes separately which is done in this contribution. Different fishing gears were used in the samplings (cylindrical nets – 1 mm mesh size, bottom trawls – 250 mm mesh size in the arms and 12 mm mesh size in the bag, beach seine – 5 mm mesh size and hook and line fishery) between September 2007 to April 2014. The specimens were sexed and the LWRs were calculated for each sex separately. There were differences between sexes in growth type, showing the importance of sexing in these studies. We reported for the first time (based on FishBase) the LWRs for two species: Ctenogobius shufeldti and Hypleurochilus fissicornis.     

Length‐weight relationships for 22 neotropical freshwater fishes from a subtropical river basin
