“…Cases of ATS are usually detected after cooking, but the phenomenon is not related to the cooking method (Casadevall et al 2020). A similar syndrome was described in cooked saddletail snapper, Lutjanus malabaricus (Bloch and Schneider 1801), and crimson snapper, L. erythropterus Bloch 1790, in Australia (Forrest et al 2014). Those authors analyzed the saddletail snapper and concluded that fish age accounted for 75.6% of the observed variation in cooked muscle texture.…”

This research aimed to explore the variability in the distribution of muscle, perivisceral, and retroperitoneal fat in Diplodus sargus during the pre-spawning period (the period of maximum accumulation of fat reserves) and its possible relationship with the abnormally tough specimen syndrome (ATS) affecting this species. Since pollutants accumulate in adipose tissue, trace metal load in the fattest specimens were also analyzed. Muscle fat content and abdominal fat were highly correlated, and larger individuals had more abundant abdominal fat. However, given its great variability (26% of the specimens had no abdominal fat at all), abdominal fat is likely a transitional fat to be quickly transferred to other tissues. The liver appeared to have a minor role as a fat deposit in D. sargus since HSI varied relatively little. None of the fishes without lipidic reserves were ATS individuals; by contrast, the only ATS individual found, a 28 cm male, showed a muscle fat content above the observed average and one of the highest amounts of perivisceral and retroperitoneal fat. Therefore, we conclude that flesh hardness is not directly related to the low lipid reserves. However, this ATS individual showed a very high liver copper concentration, suggesting a potential link between fat content, copper concentration, and ATS syndrome that should be explored in the future.

“…41,106 The significantly positive correlation between pyridinoline concentration and flesh firmness has been recognised in numerous studies. 37,[126][127][128] However, in large European sea bass with commercial size, texture parameters were not modified by dietary hydroxyproline supplementation, despite having fostered collagen deposition in the muscle. 129 Such discrepancies might be due to the contributions of collagen components on muscle texture varying in fish species and/or body size.…”

With the growing demand of consumers for high‐quality aquatic products, controlling the harvest quality of farmed fish is becoming increasingly important in aquaculture industry. The texture is a sensory property that covers a group of attributes, such as firmness, tenderness, chewiness, adhesiveness, resilience, etc., which greatly determine consumers' perception and satisfaction for flesh products. Regarding texture quality, extensive research has been conducted in recent decades based on its related theories, influencing factors, and intervention strategies. However, the information available is largely scattered and disjointed. Essentially, flesh texture is mainly determined by the collective contribution of three major muscle components: muscle fibres, intramuscular connective tissue, and intramuscular fat. Therefore, changing these components in living animals through nutritional and management factors has the potential to modulate texture quality. Here, we briefly introduced the features and development of the three muscle components mentioned above, particularly their potential contributions to texture quality of fish flesh. Exciting promises to manipulate flesh texture through dietary intervention, feed restriction, and exercise training were also discussed. To ensure their applications in large‐scale aquaculture facilities, specific considerations of these regimens should be incorporated in experimental design parameters, including the species and age of fish, research system, experiment duration, and exercise intensity. Finally, the existing challenges and limitations of fish texture studies were presented, along with some viewpoints about current work and future directions of this field.
