“…Overall, moderate to high heritability estimates were recorded for BW (0.32 ± 0.05), BL (0.36 ± 0.06) and BS (0.32 ± 0.05), suggesting substantial potential for genetic improvement of these traits in the P. monodon population studied. All these are growth-related traits and these findings corroborate the previous findings of P. monodon genetic parameter estimates ( Kenway et al, 2006 ; Macbeth et al, 2007 ; Coman et al, 2010 ; Noble et al, 2020b ), although a meta-analysis conducted by Hasan et al (2020) reported the estimates ranged from 0.18 to 0.69. Similarly Noble et al (2020b) reported the heritability estimate of 0.38 for BW trait of P. monodon for a smaller subset of this population.…”

“…From post-larval stage 15 (PL15) to harvest, the growth periods ranged from 124 to 143 days across ponds. In total 76 full sib and half-sib families were produced across 5,308 progeny and stocked across eight ponds as shown in Supplementary Material S1 and was similar to the population described by Noble et al (2020b) . Through the grow-out period, the key water quality parameters were recorded, including dissolved oxygen, temperature, pH and salinity.…”

The black tiger shrimp, Penaeus monodon, is the second most economically important aquaculture shrimp species in the world, and in Australia it is one of the most commonly farmed shrimp species. Despite its economic significance, very few studies have reported the genetic evaluation of economically important morphological size and shape traits of shrimp grown in commercial grow-out environments. In this study we obtained genetic parameter estimates and evaluated genotype-by-environment interaction (GxE) for nine body morphological traits of shrimp derived from images. The data set contained image and body weight (BW) records of 5,308 shrimp, from 64 sires and 54 dams, reared in eight grow-out ponds for an average of 133 days. From the images, landmark based morphological distances were computed from which novel morphological traits associated with size and shape were derived for genetic evaluation. These traits included body weight (BW), body length (BL), body size (BS), head size (HS), Abdominal size (AS), abdominal percentage (AP), tail tip (TT), front by back ratio (FBR), condition factor (CF) and condition factor length (CFL). We also evaluated G×E interaction effects of these traits for shrimp reared in different ponds. The heritability estimates for growth related morphological and body weight traits were moderately high (BW: h2 = 0.32 ± 0.05; BL: h2 = 0.36 ± 0.06; BS: h2 = 0.32 ± 0.05; HS: h2 = 0.31 ± 0.05; AS: h2 = 0.32 ± 0.05; and TT: h2 = 0.28 ± 0.05) and low for abdominal percentage and body shape traits (AP: h2 = 0.09 ± 0.02; FBR: h2 = 0.08 ± 0.02; CF: h2 = 0.06 ± 0.02; and CFL: h2 = 0.003 ± 0.004). G × E interaction were negligible for all traits for shrimp reared in different ponds, suggesting re-ranking is not prevalent for this population. Genetic correlations among growth related morphological traits were high ranging from 0.36 to 0.99, suggesting these traits can be simultaneously improved through indirect genetic selection. However, negative genetic correlations were observed for FBR & CF shape traits with major growth traits (ranged −0.08 to −0.95), suggesting genetic selection for rapid growth will likely result in thick/fatty shrimp over generations. Our study showed image-based landmark data can be successfully employed for genetic evaluation of complex morphological traits of shrimp and is potentially amenable to machine-learning derived parameters in semi-automated high volume phenotyping systems needed under commercial conditions.

“…In our study, fillet fat and moisture percentages showed medium heritability, and protein and collagen percentages were low. To the best of our knowledge there has been no work about fillet composition heritabilities in meagre, although similar results have been observed in other species [50,52,59,60].…”

Meagre (Argyrosomus regius) plays an important role in the aquaculture system, with the potential for diversification of European aquaculture, and is characterized by its fast growth rate, low feed conversion ratio, and the high quality of the product. Focusing on the relevance of meagre, the aim of the study was to analyze growth performance, fish morphology, and flesh composition phenotypically and genetically to be considered as a strategy in a breeding program. For this purpose, 633 fish were raised in two different housing systems, in sea cages or in a continental tank, and when they reached harvest size, manual growth traits, automatic morphology by the image analysis program IMAFISH_ML, and flesh chemical composition (fat, protein, moisture, and collagen percentages) were measured. The fish reared in the cages showed a higher body weight and fillet fat percentage than those in the tank. Heritabilities for growth and morphology traits, and for fillet fat percentage were medium, revealing these traits as a possible selection criterion in a breeding program. Phenotypic and genetic correlations between growth and morphology traits were positive and high. Phenotypic correlations between growth or morphology traits with fillet fat percentage were positive and medium; genetic correlations were not estimated accurately.
