“…For Pb, contrary to what we found, they showed a slight increase with the increase of Hi meal in the diet. Monge-Ortiz et al [ 80 ] found that FM substitution with alternative protein sources led to a decrease of As content in feed, and Hg did not show significant changes, as observed in the experimental diets of this study. However, Cd content showed a decrease passing from a diet based on FM to a diet wherein FM were replaced with corn gluten meal, krill meal, and meat and bone meal.…”

“…Cd and Hg concentrations found in experimental diets (mean, 0.47 ± 0.09, and 0.038 ± 0.002 mg kg −1 ww, respectively) of this study are of the same order of magnitude of their content in complete Atlantic salmon feed used from 2008 to 2017, 0.2–0.3 mg kg −1 ww for Cd and 0.050 ± 0.0070 mg kg −1 ww for Hg [ 10 ] or in complete feed used for Seriola dumerili (0.41-0.60 mg kg −1 ww for Cd), wherein FM has been replaced with alternative protein sources, such as corn gluten meal, krill meal, and meat and bone meal [ 80 ]. The concentration of arsenic (mean, 0.16 ± 0.05 mg kg −1 ww) was one order of magnitude lower than the complete Atlantic salmon feed in 2008–2017, 2.6 mg kg −1 ww [ 10 ] and in complete feed for Seriola dumerili , 1.86–3.15 mg kg −1 ww [ 80 ]. The Pb content of the experimental diets (mean, 0.54 ± 0.2 mg kg −1 ww) was one order of magnitude greater with respect to complete feed for Atlantic salmon from 2008 to 2017, 0.05–0.07 mg kg −1 ww [ 10 ].…”

According to the concept of circular economy, insects represent good candidates as aquafeed ingredients. Nevertheless, there are some potential chemical risks linked with insect consumption. In this study, we reared the teleost Danio rerio, used as an experimental model, with five experimental diets characterized by increasing levels (0%, 25%, 50%, 75%, and 100%) of full-fat Hermetia illucens (Hi) prepupae, substituting for fish meal (FM) and fish oil (FO). We investigated the presence of potentially toxic elements (PTEs) Cd, Pb, Ni, As, and Hg in larval (20 days), juvenile (2 months), and adult (6 months) fish. Quantitative determinations of Cd, Pb, Ni, and As were made with an atomic absorption spectrometer; the total mercury content was determined by a direct mercury analyzer. The substitution of FM and FO with Hermetia illucens meal led to a reduction in the content of some PTEs, such as Pb, As, and Ni, in fishfeed, leading to concentrations below the legal limit of undesirable substances in animal feed. By increasing the Hi meal dietary content, we observed in the Danio rerio specimens an increase in Cd, Pb, and Ni content and a reduction in As content for all life stages. Moreover, a general increase in the content of Cd, Pb, Hg, and Ni from larvae to juvenile was measured, while the shift of Danio rerio from the juvenile to the adult stage involved a significant increase in the content of Pb, Hg, and Ni. Larvae had a reduced ability to bioaccumulate metal(loid)s compared to juveniles and adults. In conclusion, the content of PTEs in Danio rerio is influenced both by the type of diet administered and by the life stage of the animal itself. This research demonstrates the possibility of using Hi prepupae as an aquafeed ingredient without exposing fish to a chemical risk and, in perspective, allows applying these eco-sustainable diets for the breeding of edible fish species, without endangering human health.

“…However, for relatively novel species for the aquaculture industry this information is rather limited. That is the case of the greater amberjack, Seriola dumerili, a pelagic teleost with great interest for the diversification of marine fish aquaculture due to its high grow rates and flesh quality (Sicuro and Luzzana, 2016;Navarro-Guilleń et al, 2019;Monge-Ortiz et al, 2020). There is scarce information related to temperature effects on the physiology of S. dumerili.…”

Biochemical features and modulation of digestive enzymes by environmental temperature in the greater amberjack, Seriola dumerili

The study of fish digestive biochemistry is essential to understand factors that affect the net efficiency of food transformation and growth, and therefore aquaculture profitability. The aim of the present study was to assess the activity and functional characteristics of key digestive enzymes in juveniles of greater amberjack (Seriola dumerili), as well as the possible modulation of their relative importance by water temperature. For that, a combination of biochemical assays and substrate-SDS-PAGE were used. Under physiological conditions pepsin activity was negligible. Chymotrypsin was the most active enzyme in the digestive tract of the greater amberjack, while lipase was the enzyme with lower activity, though both enzymes in addition to trypsin were responsive to water temperature as revealed by discriminant analysis. Seriola dumerili showed to have pH-sensitive and, except for chymotrypsin, thermally robust proteases. Inhibition assays showed the major importance of serine proteases and revealed inverse trypsin and chymotrypsin responses to environmental temperature, with higher trypsin contribution in 26°C-fish while higher chymotrypsin contribution in 18°C-fish. Zymograms revealed three isotrypsin and three isochymotrypsin enzymes, with no variation in the presence of particular isoforms among rearing temperatures. However, they confirmed the role of chymotrypsin activity in providing digestive plasticity, with one of the isoforms being more active at lower temperatures. Thus, results indicate that variation in the relative contribution of chymotrypsin isoenzymes to a particular environmental temperature occurs due to different physic-chemical features of isoforms as a source of functional flexibility. This study assessed for the first time the effects of rearing temperature on greater amberjack digestive enzymes, increasing the knowledge on its digestive biochemistry, and aiding in the improvement of management practices for this species industrialization.

“…The greater amberjack requires high temperature to grow, and these conditions can only be observed in the Algarve coast (Area E) or in the Portuguese islands such as São Miguel Island in the Azores archipelago, where cage production already exists. Fish meal substitution in the diet was possible for this species for long periods without affecting growth with water temperature maintained at 21.5 ± 2.4 • C [133]. The greater amberjack needs an increase of temperature from 19.0 • C to 24.0 • C to spawn [134] so, for hatchery implementation, Area E is the best choice.…”

Physico-chemical and biological parameters along the Portuguese coast were analyzed to evaluate the potential to produce aquatic species of economic interest. Water samples were collected in 2018 and 2019 in five different areas of the Portuguese coast. Currents data were collected between 2018 and 2020 and historical waves height data from 1988 to 2019. According to the results, there is a wide variety of species that can be considered for production. The northernmost area presented the lowest temperature, as well as the highest levels of chlorophyll a, and nitrate. Under such conditions, the rearing of salmon Salmo salar, mussel Mytilus edulis, scallop Pecten maximus, macroalgae Porphyra umbilicalis, and Undaria pinnatifida can be considered. Regarding the southernmost area, due to the highest temperature, this area seems appropriate for the production of meager Argyrosomus regius, sea bream Sparus aurata, sea bass Dicentrarchus labrax, and greater amberjack Seriola dumerili. This study highlights the challenges in deploying aquaculture structures on the Atlantic coast due to its oceanographic conditions. Site selection for aquaculture is a complex process and pilot studies are essential to analyze the feasibility of developing offshore aquaculture along the coast of Portugal.
