“…Regression equations in aquaculture species are limited to Nile tilapia (He et al, ; Silva et al, ), rainbow trout (Gümüş & Balaban, ), common carp (Kumar et al, ) and Atlantic salmon (Beddow & Ross, ; Mørkøre et al, ). In contrast, for Neotropical farmed finfish, studies parameterizing regression equations for farmed traits are still scarce (Aguilar, Cruz, Mourao, & Cyrino, ; Furuya, Michelato, Cruz, & Furuya, ). Our regression equation predicting LEA estimated 84% of the total variance.…”

Estimating components of variance and genetic parameters of economically relevant traits is the first step towards planning a breeding program for aquaculture species. This study estimated the (co)variance components for growth rate and other body traits and then determined a multiple regression equation to assess the loin eye area (LEA) from morphometric traits of the Neotropical aquaculture species Colossoma macropomum. Estimation of variance components was performed using derivative‐free restricted maximum likelihood estimation using the MTDFREML package. Six predictive variables were tested to estimate the coefficient of regression equation and to select the most suitable model for predicting LEA. The estimated genetic parameter for body weight showed moderate‐to‐high heritability estimates of 0.26 (0.01) and 0.49 (0.01) at 221 and 623 days respectively. The genetic correlation (rg) estimates between body size measurements were positive and ranged from low to high at both ages. The heritability for LEA in this assessment was 0.39 (0.03). The genetic and phenotypic correlations between LEA and the other body measurements ranged from 0.16 to 0.94 and 0.75 and 0.90 respectively. The outcomes of this study can contribute to the development of a genetics‐based breeding program that will improve (tambaqui) productivity and carcass quality.

“…Knowledge of this relationship finds applications in fisheries biology and in the assessment of fish stocks (Kochzius, 1997). Length-weight relationships allow conversion of growth-inlength into growth-in-weight in stock assessment models of biomass from length frequency distributions, and estimation of fish condition (Petrakis and Stergiou, 1995;Morato et al, 2001;Furuya et al, 2014). Length-weight relationship is of great importance in fishery assessments (Garcia et al, 1989;Haimovici and Velasco, 2000).…”

“…The LWRs has been studied by many researchers in different fish species viz., Clarias gariepinus (Ayo-Olalusi, 2014); Oreochromis niloticus (Silva et al, 2015); Astyanax aff. fasciatus (Furuya et al, 2014); Pseudorasbora parva, Atherina boyeri, Aphanius danfordii, Tinca tinca, and Cyprinus carpio (Kırankaya et al, 2014); Capoeta umbla (Serdar and Özcan, 2016); Acanthobrama marmid, Capoeta trutta, Arbus luteus and Chalcalburnus mossulensis (Başusta and Çiçek, 2006); Carasobarbus luteus, Chondrostoma regium, Clarias gariepinus, Anguilla anguilla and Cyprinus carpio (Özcan, 2008). In addition, the a and b values, which are the LWR parameters, allow the morphology of populations distributed in different habitats and the life processes of fish species to be compared (Yedier et al, 2019;Yılmaz et al, 2010).…”

The Length-weight relationships (LWRs) are very important to data for accurate estimate of populations in stock menagement. In this study, the length-weight relationships of some fish in Göynük stream, Murat River (Bingöl/Turkey) were examined. The LWRs and condition factor (K) of Cyprinon macrostomus, Gara rufa, Barbus lacerta, and Acanthobrama marmid were analyzed. LWRs was estimated using the linear regression model. LWRs were obtained as TW = 0.013L2.98, 0.057L2.40, 0.016L2.79 and 0.029L2.82 for C. macrostomus, G. rufa, B. lacerta and A.marmid, respectively. The b values acquired in the four fish species ranged from 2.13 (G. rufa-Male) to 3.34 (B. lacerta-Male). The K of the fish species varied from 0.90 (A. marmid-Male) to 1.27 (G. rufa-All), indicating that most of the fish were in good condition. However, C. macrostomus and G. rufa were better condition than B. lacerta and A. marmid. The study has provided baseline information on the LWR and K of the fish species in Göynük Stream. The datas that would be useful to adapt the adequate regulations for sustainable fish stock estimation in the stream for fishery biologist.
