“…On the other hand, determination of the specific growth rate (SGR) provides a valuable tool to identify specific periods of high growth rates ( Ricker, 1975 ). In the present study, shrimp showed a significantly higher SGR during the feeding recovery period, revealing a compensatory response, as observed in other studies conducted on the same species ( Yu et al, 2008 ; Liu et al, 2022 ) and also in the Chinese shrimp F. chinensis ( Zhang et al, 2010 ), in the Oriental river prawn Macrobrachium nipponense ( Li et al, 2009 ) and in the crayfish Cherax quaricarinatus ( Stumpf, Tropea & Greco, 2014 ; Stumpf & López Greco, 2015 ).…”

“…In this respect, Jobling (2010) describes that a recovery growth is a convergence between the compensatory growth and a catch-up growth. Moreover, feed restriction combined with other factors such as stocking density or temperature can also affect the compensatory response ( Stumpf et al, 2019 ; Liu et al, 2022 ; Prates et al, 2023 ).…”

“…In farmed shrimp, feed restriction has been evaluated at different degrees of restriction and time periods, where shrimp has showed full compensatory growth with a concomitant significant reduction on feed utilization ( Maciel, Francisco & Miranda-Filho, 2018 ; Liu et al, 2022 ), and in other cases with partial growth recovery ( Yildirim & Aktaş, 2019 ; Rocha et al, 2019 ). Furthermore, other benefit of the use of this strategy is the reduction in nitrogen and phosphorous residual compounds in the farm effluents and environment ( Zhu et al, 2016 ; Lucas, Southgate & Tucker, 2019 ).…”

The present work aimed to evaluate the effects promoted by a phase of compensatory growth on metabolic turnover rate, digestive enzyme activity, and bacterial biota of the Pacific white shrimp Litopenaeus vannamei kept under different feeding regimes. Three treatments were evaluated as follows: 70% feed restriction during 3 (T3) and 6 (T6) days, followed by a period of feeding to satiety, and a control treatment without restriction periods. The results showed a full compensatory growth in treatments T3 and T6 by day 35 of the bioassay. A significant increase in trypsin and lipase (T6) activities was observed during compensatory growth, whereas specific amylase activity was significantly lower in treatment T6 compared to T3 but not significantly different from the control group. To determine the metabolic turnover rate of nitrogen in muscle tissue, an analysis of nitrogen isotope values (δ15N) at natural abundance levels was performed. At the end of the experimental period, shrimp under feed restriction had lower metabolic turnover rates and longer nitrogen residence times (t50) in muscle tissue, as compared to individuals in the control treatment. Regarding the changes in the bacterial communities in shrimp gut, no significant differences were observed at the phylum level, with Proteobacteria being the most abundant bacteria, followed by Actinobacteria. At family taxa level, Rhodobacteraceae presented the highest relative abundance in all treatments, whereas a decrease in Vibrionaceae was observed in treatments T3 and T6 when compared to control shrimps during compensatory growth. At the genus level, a decrease in Celeribacter, Catenococcus, and Epibacterium, and an increase in Ruegeria and Shimia, were identified in shrimp subjected to feed restriction when compared to control organisms during compensatory growth (day 14). At the end of the experimental period, the evaluated parameters showed similar results as those observed in the control treatment, suggesting a normalization of the metabolism and the physiological state. The present findings contribute to a better understanding on the physiological effects produced during compensatory growth in shrimp, which in turn could assist in the development of improved feeding strategies in benefit of the aquaculture industry.

“…Transcriptomics has assisted in the identification of RTKs in crustacean tissues, but these receptors have not been fully characterized (17,26,(31)(32)(33)(34)(35)(36)(37)(38)(39). Moreover, annotation and characterization of RTKs in diverse crustacean taxa has been hampered by databases that are limited to a relatively small number of species and taxonomic groups.…”

Receptor tyrosine kinases (RTKs) mediate the actions of growth factors in metazoans. In decapod crustaceans, RTKs are implicated in various physiological processes, such molting and growth, limb regeneration, reproduction and sexual differentiation, and innate immunity. RTKs are organized into two main types: insulin receptors (InsRs) and growth factor receptors, which include epidermal growth factor receptor (EGFR), fibroblast growth factor receptor (FGFR), vascular endothelial growth factor receptor (VEGFR), and platelet-derived growth factor receptor (PDGFR). The identities of crustacean RTK genes are incomplete. A phylogenetic analysis of the CrusTome transcriptome database, which included all major crustacean taxa, showed that RTK sequences segregated into receptor clades representing InsR (72 sequences), EGFR (228 sequences), FGFR (129 sequences), and PDGFR/VEGFR (PVR; 235 sequences). These four receptor families were distinguished by the domain organization of the extracellular N-terminal region and motif sequences in the protein kinase catalytic domain in the C-terminus or the ligand-binding domain in the N-terminus. EGFR1 formed a single monophyletic group, while the other RTK sequences were divided into subclades, designated InsR1-3, FGFR1-3, and PVR1-2. In decapods, isoforms within the RTK subclades were common. InsRs were characterized by leucine-rich repeat, furin-like cysteine-rich, and fibronectin type 3 domains in the N-terminus. EGFRs had leucine-rich repeat, furin-like cysteine-rich, and growth factor IV domains. N-terminal regions of FGFR1 had one to three immunoglobulin-like domains, whereas FGFR2 had a cadherin tandem repeat domain. PVRs had between two and five immunoglobulin-like domains. A classification nomenclature of the four RTK classes, based on phylogenetic analysis and multiple sequence alignments, is proposed.

“…Shrimp is highly appreciated worldwide, it has a high protein content and a low percentage of fat (Duray et al, 2022;Golder et al, 2022;Liu et al, 2022;Tanjung et al, 2022). The health, safety, and overall quality of shrimp cultivation profoundly hinge on various factors, including water quality, feed composition, and the mineral content in shrimp (Kawan et al, 2019;Amir et al, 2021;Bull et al, 2021;Vieira et al, 2021).…”

The objective of this work was to analyze the contamination by iron (Fe) and zinc (Zn) in the shrimp Macrobrachcium amazonicum in the region of the mouth of the Amazon River in the State of Amapá, taking into account aquaculture and fishing activities. 90 shrimp were used, 45 females and 45 males of M. amazonicum. The animals (30) were found in three different points, being Mazagão Velho in Mazagão, a community on Ilha de Santana, a district in the Brazilian municipality of Santana and Arquipélago do Bailique. Fe and Zn determinations were performed by conventional flame atomic absorption spectrophotometry. The greatest accumulation of Zn in the organs and the lowest concentration of Zn in the muscle and exoskeleton of M. amazonicum was observed. Fe had the highest accumulation in organs, followed by exoskeleton and muscle. Zn accumulation in male organs was greater than in muscle and exoskeleton while Fe concentrations were greater in organs, followed by exoskeleton and muscle. In females, Zn accumulation was greater in our organs, with no difference between muscle and exoskeleton. According to the present study, to maintain levels of food security, the consumption of freshwater shrimp caught and farmed in Mazagão, Bailique Archipelago and community of Ilha de Santana should be limited to a daily shrimp intake dose of 96. 52 g for Fe and 226.81 g for Zn.
