“…Another regulatory peptide produced by adipocytes to be considered is apelin. In mammals, apelin and its receptor, that belongs to the type 1 angiotensin G protein-coupled receptor family ( 162 ), are expressed in adipose tissue but also widely distributed in other peripheral tissues in goldfish ( 162 ), Ya-fish ( Schizothorax prenanti ) ( 163 ), and others ( 164 ). Apelin has multiple roles, according to the numerous locations where it is found.…”

Control of tissue metabolism and growth involves interactions between organs, tissues, and cell types, mediated by cytokines or direct communication through cellular exchanges. Indeed, over the past decades, many peptides produced by adipose tissue, skeletal muscle and bone named adipokines, myokines and osteokines respectively, have been identified in mammals playing key roles in organ/tissue development and function. Some of them are released into the circulation acting as classical hormones, but they can also act locally showing autocrine/paracrine effects. In recent years, some of these cytokines have been identified in fish models of biomedical or agronomic interest. In this review, we will present their state of the art focusing on local actions and inter-tissue effects. Adipokines reported in fish adipocytes include adiponectin and leptin among others. We will focus on their structure characteristics, gene expression, receptors, and effects, in the adipose tissue itself, mainly regulating cell differentiation and metabolism, but in muscle and bone as target tissues too. Moreover, lipid metabolites, named lipokines, can also act as signaling molecules regulating metabolic homeostasis. Regarding myokines, the best documented in fish are myostatin and the insulin-like growth factors. This review summarizes their characteristics at a molecular level, and describes both, autocrine effects and interactions with adipose tissue and bone. Nonetheless, our understanding of the functions and mechanisms of action of many of these cytokines is still largely incomplete in fish, especially concerning osteokines (i.e., osteocalcin), whose potential cross talking roles remain to be elucidated. Furthermore, by using selective breeding or genetic tools, the formation of a specific tissue can be altered, highlighting the consequences on other tissues, and allowing the identification of communication signals. The specific effects of identified cytokines validated through in vitro models or in vivo trials will be described. Moreover, future scientific fronts (i.e., exosomes) and tools (i.e., co-cultures, organoids) for a better understanding of inter-organ crosstalk in fish will also be presented. As a final consideration, further identification of molecules involved in inter-tissue communication will open new avenues of knowledge in the control of fish homeostasis, as well as possible strategies to be applied in aquaculture or biomedicine.

“…The morning feeding activity of fish is even more pronounced in fi 3, with 76-90% of demands recorded before noon (Figure 4A). There is limited information on how these seasonal or circannual rhythms influence feeding behaviour in fish, making it complex to give a straightforward conclusion about feeding activities and associated seasonal changes (Assan et al, 2021). Nevertheless, we can reasonably assume that the seasonal difference between the fi periods (autumn for fi1 and spring-summer for fi2 and fi3) may, at least partially, explain the changes observed in the daily feeding profile.…”

Accurately measuring individual feed intake is required to include feed efficiency (FE) as an objective in commercial breeding programs. Phenotyping individual feed intake through direct measurements remains complex in fish reared in groups. One way to overcome this challenge is to find proxies for estimating FE. This study aimed to investigate the correlations between fish FE and potential predictive criteria in rainbow trout Oncorhynchus mykiss. As predictive criteria, we considered the variations of body weight assessed as thermal growth coefficients (TGC) and the feeding behaviour assessed as the number of feed demands over a period and the proportion of the demands made before noon. Feed intake was assessed over three different periods in ten isogenic lines allowing a recording for each of the ten genotypes while keeping fish in groups. The protocol consisted of two successive feed deprivation and refeeding phases after initial basal growth periods. Correlations were then calculated between FE, measured either as feed conversion ratio (FCR) or residual feed intake (RFI), and the different indirect criteria. We found positive phenotypic correlations between FCR and RFI over the feed intake measurement periods (r greater than or equal to 0.79, P < 0.001). Assessment of the relationship between FE traits (FCR and RFI) calculated over the three measurement periods and TGC revealed no significant association. We found significant positive correlations between RFI calculated from the first feed intake measurement period and feeding behaviour, assessed as the number of feed demands (r = 0.42-0.49, P less than or equal to 0.022). Nevertheless, such correlations were not established for the two other measurement periods following feed deprivation. While we demonstrated that the weight variations during feed deprivation are not a good proxy for FE (FCR or RFI) in rainbow trout, we also highlighted the interest in exploring more the relationships between FE and feeding behaviour in fish.

“…Intake of nutrition is a very significant inward factor in fish. As the foremost behaviour of fish, feeding is to provide fish with nutrients and energy for survival, growth and reproduction (Assan et al, 2021), optimization of food intake generally contributes to enhanced growth, increased immunity and improved flesh quality (Xu et al, 2020). Irrespective of environmental factors (feeding manipulation, stress and water temperature) that influence feeding behaviours and feed utilization, response to feed intake, diet palatability and digestibility differ because of the difference in fish feed components (Zhou et al, 2018).…”

The supply of a balanced portion of nutrition is vital for the success of the restocking program of the Yangtze sturgeon, an endangered sturgeon in the Yangtze River, however, knowledge of the nutritional requirement of this endangered species is scarce. The present study was performed to investigate the optimum dietary lipid requirement of the Yangtze sturgeon juveniles (initial weight, 184.24 ± 6.79 g). Five isonitrogenous diets containing a mixture of fish oil and soybean oil (1:1 ratio) at five different levels (35, 63, 90, 124 and 168 g/kg) were prepared and each prescribed diet was hand‐fed to triplicate groups of fish for 50 days. Results showed that feed intake of fish was not affected, but growth and feed utilization rate increased and then declined with the increment of dietary lipid content. Similar trends were observed for the activities of enzymes involved in lipid digestion and metabolism. The lipid content of fish dorsal muscle and liver together with serum triglyceride content was linearly elevated with increasing inclusion of dietary lipid. The inclusion of 12.4% dietary lipid significantly reduced the content of deamination product ammonia in serum. Excessive lipid intake caused noticeable hepatocellular vacuolation as shown by histological staining. Based on the regression analysis between growth response and dietary lipid levels, the optimum dietary lipid level of juvenile Yangtze sturgeon was estimated to be 141.67 g/kg diet.
