Weight–length and length–length relationships for reef fish species from the Cape Verde Archipelago (tropical north‐eastern Atlantic)

This study reports weight–length and length–length relationships for selected coastal reef fish species of the Cape Verde Archipelago (tropical north‐eastern Atlantic). Specimens were caught with different types of gear (long‐lines, hand‐lines, purse‐seines and traps) during commercial fishing activities and sampled during fish market operations. A total of 8328 individuals were sampled, representing 29 species from 14 Families. This study provides the first references on weight–length and length–length relationships for five and 23 fish species worldwide, for 10 and 24 species for the Eastern Atlantic and for 12 and 26 species for Cape Verde Archipelago, respectively. Additionally, it provides revised weight–length relationships for 11 species from Cape Verde waters.     

Length‐weight and length‐length relationships of five fish species from the Zigui section of the lower Three Gorges Reservoir,Hubei Province,China

This paper provides the length‐weight and length–length relationships for five fish species in the Zigui section of the lower Three Gorges Reservoir of the Yangtze River. Specimens were collected from December 2014 to January 2017, using various types of fishing gear and electroshock fishing techniques. Length‐weight relationships (LWRs) for one fish species and Length–length relationships (LLRs) for five fish species are unknown to FishBase. New maximum total lengths for four species were also recorded for FishBase. Moreover, standard‐length to total‐length equations for converting size measurements for these five species are presented.

Length‐weight relationships for 26 species are unknown to FishBase and new maximum lengths are recorded for 20 species. These results are useful for fishery research, conservation and management in the Hongshui River.     

Length‐weight relationships for 11 fish species from the tributary of Amur River (Fuyuan,NE China)

Length‐weight relationships for nine nemacheilian loaches (Teleostei: Nemacheilidae) from Iran

Length‐weight relationships were estimated for 9 nemacheilian loaches of Iran. Four of these species are endemic to Iran and the L‐W parameters of six species are given for the first time. Significant length‐weight relationships with high correlation coefficient were found for all species. The value of parameter b ranged from 2.81 to 3.12.     

Length‐weight relationships of 11 fish species from the upper Jinsha River,China

Length‐weight relationships (LWR) are described for eleven indigenous fishes from the upper Jinsha River, which is the upper stretch of the Yangtze River, China. This is the first record of length‐weight relationships for ten of these species in FishBase and new maximum lengths are recorded for seven species.     

Length‐weight relationships for 15 fish species from Atlantic rain forest streams,southeastern Brazil

Length‐weight relationships were determined for 15 fish species from the tributary Atlantic rain forest steams that drain into Sepetiba Bay, southeastern Brazil. This is the first record of length‐weight relationships for 12 of these species and new maximum lengths for four species. These results will be useful for management and conservation of this area of the Atlantic rain forest drainages.     

Length–weight and length–length relationships for some Yangtze River fishes in Tian‐e‐zhou Oxbow,China

Length–weight and length–length relationships are reported for 32 fish species belonging to seven families and 26 genera from the Tian‐e‐zhou Oxbow in the middle reach of Yangtze River, near Shishou City, China. The weight (W) ‐ length (L) relationships were estimated using the logarithmic form of the equation W = aL^b. The exponent b varied from 2.60 to 3.65 (mean ± SE: 3.12 ± 0.25). The 14 weight–length relationships, 13 length–length relationships, and seven maximum lengths are presented to FishBase for the first time.     

Length‐weight relationships for 18 freshwater fish species from the Nakdong River in South Korea

Length‐weight relationships of 18 freshwater fish species from the Nakdong River in South Korea are presented. Length‐weight relationship data for 10 of these species were not available previously.     

Length–weight and length–length relationships of four native fish species from the Yalong River,China

Length‐weight and length‐length relationships were estimated for four native fish species from the Yalong River and its tributaries, China. A total of 976 specimens were collected monthly using trap nets and electric fishing in May 2013 and July 2015 to February 2016. This study presents the first references on LWRs (length–weight relationships) and LLRs (length–length relationships) for three species (Gymnocypris firmispinatus, Paracobitis variegatus and Euchiloglanis kishinouyei). Moreover, maturation length, absolute fecundity and predominant food items for the four species were also described in the study.     

Length–weight relationships of fishes in Chi‐gu black‐spoonbill reserve area of Taiwan

Length‐weight relationships for five Clupeiformes species from the Persian Gulf and Oman Sea

Length‐weight relationships (LWRs) were determined for five Clupeiformes species representing three families collected from the Persian Gulf and Oman Sea. These are the first references on length‐weight relationships for two of these species (Ilisha megaloptera and Sardinella sindensis). A new maximum length record was obtained for one species (Ilisha melastoma).     

Length‐weight relationships of fish species in Kordan River (Namak Lake basin), Iran
