Dietary sodium heptanoate helps to improve feed efficiency, growth hormone status and swimming performance in gilthead sea bream (
            Sparus aurata
            )

The development of a homologous radioimmunoassay (RIA) for gilthead sea bream growth hormone (sbGH) is described. RIA sensitivity was 0.4 ng/mL, and ED50 was 1.74 ± 0.05 ng/mL. Intra- and inter-assay coefficients of variation were 3.4 and 8.8%, respectively, at ED50 levels. Mammalian growth hormones (GH), carp gonadotropin, chinook salmon gonadotropin, ovine porlactin, and recombinant tilapia prolactin did not show cross-reactivity. Serial dilutions of recombinant trout GH indicated a low but significant cross-reactivity. The displacement curves for plasma and pituitary homogenates from sparid fish (gilthead sea bream, blacktail, white sea bream, Couch's sea bream, and marmor-brassen) were parallel to that of the sbGH standard. Pituitary homogenates from other perciform fish tested (gaper, grey mullet, red mullet, and sea pike) also showed parallel slopes of inhibition. Pituitary homogenates from common sole, sea scorpion, forked hake, goldfish, rainbow trout, and European eel showed low or negligible cross-reactivity. These results suggest that the GHs of perciform fish have a number of similarities in structure. RIA of sea bream GH can be used to quantify the GH of sparid fish and perciform fish, provided a validation has been carried out.

Aerobic And Anaerobic

Measurement of metabolic rates provides a valuable proxy for the energetic costs of different living activities. However, such measurements are not easy to perform in free-swimming fish. Therefore, mapping acceleration from accelerometer tags with oxygen consumption rates (MO2) is a promising method to counter these limitations and could represent a tool for remotely estimating MO2 in aquaculture environments. In this study, we monitored the swimming performance and MO2 of 79 gilthead sea bream (Sparus aurata; weight range, 219–971 g) during a critical swimming test. Among all the fish challenged, 27 were implanted with electromyography (EMG) electrodes, and 27 were implanted with accelerometer tags to monitor the activation pattern of the red/white muscles during swimming. Additionally, we correlated the acceleration recorded by the tag with the MO2. Overall, we found no significant differences in swimming performance, metabolic traits, and swimming efficiency between the tagged and untagged fish. The acceleration recorded by the tag was successfully correlated with MO2. Additionally, through EMG analyses, we determined the activities of the red and white muscles, which are indicative of the contributions of aerobic and anaerobic metabolisms until reaching critical swimming speed. By obtaining insights into both aerobic and anaerobic metabolisms, sensor mapping with physiological data may be useful for the purposes of aquaculture health/welfare remote monitoring of the gilthead sea bream, a key species in European marine aquaculture.
