“…Growth hormone from the anterior pituitary binds to hepatic GH receptors and stimulates the liver to synthesize and release IGF-1 into the circulation system; this directly stimulates somatic tissue growth via binding to IGF-1 receptors in the tissues but also generates negative feedback on pituitary GH synthesis and release (Donaldson 1981;McLean and Donaldson 1993). Hack et al (2018Hack et al ( , 2019 reported that plasma IGF-1 concentrations were positively correlated with an individual fish's growth rate in patterns that were directly linked to differences in food intake. Thus, our results suggest that the high stocking density causes a reduced growth rate in cultured Black Rockfish by decreasing the plasma IGF-1 concentration.…”

The objective of the current study was to evaluate the effect of stocking density on juvenile Black Rockfish Sebastes schlegelii (average weight = 12 g) in terms of stress, hematological responses, and growth performance during a 4‐month growth trial in a flow‐through system. The initial stocking densities were 1.3 kg/m3 (low), 1.8 kg/m3 (medium), and 2.3 kg/m3 (high), and the final densities were 4.9 kg/m3 (low), 5.6 kg/m3 (medium), and 6.3 kg/m3 (high). At the end of the trial, the high stocking density significantly affected growth characteristics, levels of growth hormone and insulin‐like growth factor 1, and hematological indices (hematocrit, red blood cell count, and hemoglobin level) compared to the medium and low stocking densities. The plasma cortisol and immunoglobulin‐M levels were significantly higher at the high density than at the other two densities. Taken together, while the low and medium stocking densities (final densities of up to 5.6 kg/m3) did not affect stress and hematological indices or growth, the high stocking density (final density of 6.3 kg/m3) significantly impacted those variables, which suggests an allostatic load at that density. Thus, the use of a final stocking density less than 6.3 kg/m3 should be considered to avoid compromising the stress and health condition and growth of Black Rockfish at this size and temperature range.

“…Other genomic indicators were not strongly affected by temperature. Beckman, 2011), including rockfish Sebastes serranoides reared under laboratory conditions, and indicates that differences in expression may be attributed to the quantity of ingested food (Hack et al, 2018). We also expected that high liver igf-1 expression would be correlated with a high expression of white muscle igf1-ra, since IGF-1 binds to receptors on the surface of muscle cells to exert its action on muscle growth.…”

“…It has been shown that measures of IGF-1 (plasma concentration and liver mRNA levels) are also strongly correlated with specific growth rate in several teleost species and could be used as a proxy for growth (reviewed by Beckman, 2011). Indeed, plasma IGF-1 has a significant positive correlation with liver igf-1 mRNA and specific growth rate in species closely related to deepwater redfish, such as olive rockfish Sebastes serranoides (Hack et al, 2018) and copper rockfish Sebastes caurinus (Hack et al, 2019) as well as in other fish species such as rainbow trout Oncorhynchus mykiss (Gabillard et al, 2003) and chinook salmon O. tshawytscha (Pierce et 5 al., 2005). Plasma IGF-1 also has a significant positive correlation with muscle igf-1 mRNA in the hybrid striped bass Morone chrysops × Morone saxatilis (Picha et al, 2008).…”

Deepwater redfish Sebastes mentella will be among the most important resource-sustaining commercial bottom-fish fisheries in the years to come in the Estuary and Gulf of St. Lawrence (EGSL). In 2011, 2012, and 2013, three strong cohorts were recruited to the stock; their abundance in 2018 was 80 times higher than that of the 1993–2012 period. The main goal of this work was to deepen our knowledge of their growth regulation and metabolism in order to identify molecular indicators and determine how they are influenced by natural environmental conditions. Fish weight and water temperature explained 11% of the variation in relative mRNA levels of specific gene targets in liver and muscle among seven sites where deepwater redfish were captured in the EGSL. The relative expression of liver insulin-like growth factor-1 (igf-1) and white muscle A-chain lactate dehydrogenase (ldh-a) correlate positively with weight, whereas heavy chain muscle myosin (myo), heart citrate synthase (cs), and white muscle pyruvate kinase (pk) correlate negatively. The relative expression of heart cytochrome c oxidase subunit 1 (cox-1) and white muscle igf-1 receptor isoform a (igf-1ra) correlate negatively with temperature. Deepwater redfish from the estuary were smaller than those caught at other sites. Since the growth potential of deepwater redfish was strongly correlated with temperature (being enhanced by higher temperatures), this study suggests an ecological advantage for this species in a climate-warming context.

“…210 Since changes in plasma IGF-1 levels are directly correlated with growth arrest and acceleration during variations in feed availability, it is reasonable to assume it is a valid marker of compensatory growth in fish. 75,192,210,211 Other hormones, such as other IGFs or thyroid hormones, have proven to influence fish growth. Although not detailed here, analysis of their possible consideration as markers of growth in fish could be interesting.…”

Compensatory growth: Fitness cost in farmed fish and crustaceans

Feed restriction in fish and crustaceans is gaining interest due to its unusual acceleration of growth after a feed deprivation period. This phenomenon, known as compensatory growth, allows deprived organisms to reach the weight of never‐stressed counterpart organisms. Since feed is the major economic and ecological burden of fish and crustaceans farming, succeeding to reduce its quantity without loss of production may enhance a sustainable aquaculture development. A wide variety of restriction/feeding protocols, involving differences in nature, duration and intensity, have been tested on aquatic organisms. However, not all of them lead to optimal compensatory growth. Furthermore, before extending this practice to industrial setting, it is essential to assess physiological costs associated with both food restriction and compensatory growth. Indeed, although fish and crustaceans appear to be tolerant to dietary restriction, it involves metabolic, digestive, oxidative and immune changes. Nevertheless, return to basal values is not always achieved through refeeding. Compensatory growth has been observed and described in many taxa; however, physiological mechanisms during this process are poorly understood. On the other hand, the acceleration of growth itself appears to generate physiological consequences in organisms, particularly through the generation of oxidative stress. This review provides an overview of the fitness consequences associated with dietary restriction and the subsequent enigmatic compensatory growth in fish and crustaceans.
