    Abstract The regression of fisheries in the Gulf of Cadiz is evident since current fish catches are 33% of that 30 years before. Consequently, some initiatives for the replenishment of exhausted wild stocks are welcome. The objective of the present work is to describe and analyse the results coming from the first flatfish stock enhancements in Andalusia. A total of 3189 fish from three flatfish species: Senegal sole (Solea senegalensis Kaup), wedge sole (Dicologlossa cuneata Moreau), and brill (Scophthalmus rhombus Linnaeus) were tagged and released. Several variables were calculated through the data analysis of recovered fish. Some variables were calculated only for Senegal soles since wedge sole and brill recaptures were not significant. The Senegal sole recapture rate was 2.71 ± 0.72, similar to other published data, the recapture rates for bigger fish being higher though not significant. No significant differences were detected for distance, time, growth, or recapture rate amongst initial Senegal sole sizes. Around 80% of recaptures were registered within 15 weeks after release. The results show that it is possible for the release and recovery of tagged Senegal soles in the Gulf of Cadiz. Future long-term programmes on stock enhancement could help to determine the effects on fisheries and recover stocks.

    Abstract In the last years, studies on stress attenuation in fish have progressively grown. This is mainly due to the interest of institutions, producers, aquarists and consumers in improving the welfare of farmed fish. In addition to the development of new technologies to improve environmental conditions of cultured fish, the inclusion of beneficial additives in the daily meal in order to mitigate the stress response to typical stressors (netting, overcrowding, handling, etc.) has been an important research topic. Fish are a highly diverse paraphyletic group (over 27,000 species) though teleost infraclass include around 96% of fish species. Since those species are distributed world-wide, a high number of different habitats and vital requirements exist, including a wide range of environmental conditions determining specifically the stress response. Although the generalized endocrine response to stress (based on the release of catecholamines and corticosteroids) is detectable and therefore provides essential information, a high diversity of physiological effects have been described depending on species. Moreover, recent omics techniques have provided a powerful tool for detecting specific differences regarding the stress response. For instance, for transcriptomic approaches, the gene expression of neuropeptides and other proteins acting as hormonal precursors during stress has been assessed in some fish species. The use of different additives in fish diets to mitigate stress responses has been deeply studied. Besides the species factor, the additive type also plays a pivotal role in the differentiation of the stress response. In the literature, several types of feed supplements in different species have been assayed, deriving in a series of physiological responses which have not focused exclusively on the stress system. Immunological, nutritional and metabolic changes have been reported in these experiments, always associated to endocrine processes. The biochemical nature and physiological functionality of those feed additives strongly affect the stress response and, in fact, these can act as neurotransmitters or hormone precursors, energy substrates, cofactors and other essential elements, implying multi-systematic and multi-organic responses. In this review, the different physiological responses among fish species fed stress-attenuating diets based on biomolecules and minerals have been assessed, focusing on the endocrine regulation and its physiological effects.

    Abstract Inflammation may negatively impact health, particularly that of the central nervous system. Phenolic compounds are bioactive molecules present in fruits and vegetables with potential anti-inflammatory effects. The purpose of the present work is to review the immunomodulatory bioactivities of phenolic compounds in the periphery and in the central nervous system. Results show that various types of phenolics are able to counter diet- or pathogen-induced systemic inflammation (among others) in various models. In vitro data show significant effects of flavonoids and phenolic acids in particular; similar bioactivities were reported in vivo, when administering them as pure compounds or from fruit and vegetable extracts that contain them. In the central nervous system, phenolics counter chronic inflammation and aggressive acute inflammatory processes, such as ischemic events, when administered preemptively and even therapeutically. We therefore conclude that the immunomodulatory potential of phenolic compounds can maintain an adequate immune response; their regular consumption should therefore be prioritized in order to maintain health. PRACTICAL APPLICATIONS: The immune response must be carefully regulated in order to avoid its deleterious effects. The present work highlights how phenolic compounds, dietary components ubiquitous in everyday diet, are able to maintain it within an adequate range. As humans are exposed to more proinflammatory stimuli (inadequate dietary pattern, mental stress, environmental pollution, chronic diseases, etc.), it becomes necessary to counter them, and consuming adequate amounts of foods that contain compounds with this ability is a rather simple strategy. Thus, the present work highlights how fruits and vegetables can help to maintain an adequate immune response that can preserve systemic health and that of the central nervous system. Furthermore, specific compounds contained in them can also be ideal candidates for additional in-depth studies, which can potentially lead to the development of potent, targeted, and safe anti-inflammatory molecules.

    Abstract Seizure-mediated oxidative stress is a crucial mechanism in the pathophysiology of epilepsy. This study evaluated the antioxidant effects of daytime-restricted feeding (DRF) and the role of the Nrf2 signaling pathway in a lithium-pilocarpine model seizure model that induces status epilepticus (SE). We performed a lipoperoxidation assay and dihydroethidium fluorescence to measure oxidative stress markers in the hippocampus (malondialdehyde and reactive oxygen species). The protein content of Nrf2 and its downstream protein SOD2 was evaluated using Western blotting. The cellular distribution of the Nrf2 and SOD2 proteins in the pyramidal cell layer of both the CA1 and CA3 hippocampal subfields and astrocytes (GFAP marker) were quantified using immunofluorescence and immunohistochemistry, respectively. Our results indicate that DRF reduced the malondialdehyde levels and the production of reactive oxygen species. Furthermore, a significant increase in Nrf2 and SOD2 protein content was observed in animals subjected to restrictive diet. In addition, DRF increased the relative intensity of the Nrf2 fluorescence in the perinuclear and nuclear compartments of pyramidal neurons in the CA1 subfield. Nrf2 immunoreactivity and the astrocyte marker GFAP also increased their colocalization under DRF conditions. Additionally, SOD2 immunoreactivity was increased in CA1 pyramidal neurons but not in the CA3 region. Our findings suggest that DRF partially prevents oxidative stress by increasing the Nrf2 transcriptional factor and the SOD2 enzyme during the development of SE.

    Abstract Avocado paste (AP) is the main industrial byproduct of its processing, and retains various phenolic compounds (PCs). PCs are known to normalize the plasma lipid profile, but those from avocado byproducts have been minimally studied. We report the normalizing effects of an AP-derived phenolic extract (PE) on the plasma lipid profile of male Wistar rats. A standard (SD) and high-fat diet (HFD) were formulated, and the same diets were supplemented with 1 g/kg of diet of PE (SD + PE and HFD + PE). Rats were fed these diets during an 8-week period. The HFD induced signs of dyslipidemia, but PE treatment countered the decrease in HDL. Relative mRNA expression (real-time PCR) of the hepatic HDL receptor (SCARB1) increased in both groups (SD + PE and HFD + PE), while the LDR receptor (LDLR) increased in SD + PE group. The mRNA expression of apolipoproteins APOA1 and APOB was unaffected. We conclude that PCs from AP can counter a diet-induced decrease in plasma HDL by acting on the mRNA expression of its hepatic receptor.

    Abstract Knowledge of individual behavioural variations (coping styles) can be a very useful tool for aquaculture, since it could allow to adapt the culture conditions to the different behavioural traits and, thus, to reduce the stress in the fish getting in this way a better production. The objective of this work was the identification of coping styles and their possible association with energy metabolism enzyme activities in the wedge sole (Dicologlossa cuneata). After submitting the fish to different tests (Feeding Recovery, Novel Object, Aggression and Restraining), the results showed a high individual variation, especially in the adaptation to a new environment (CV = 90.92 %), latency to escape (CV = 114.14 %) and plasma cortisol levels (CV = 105.56 %), thus showing the existence of coping styles in this species. Two different personalities were defined: the CS1 group (reactive individuals) and the CS2 group (proactive individuals). The CS1, unlike the CS2, presented a shorter latency to escape, higher number of escape attempts, a longer duration of escape attempts, and higher plasma cortisol levels after an acute stress. In addition, significant differences were detected for Glycogen phosphorylase (GPase) that acts in glycogenolysis, presenting the group CS1 the highest values (0.80 ± 0.17 vs. 0.48 ± 0.02 U mg prot⁻¹). In conclusion, this study demonstrates for the first time the existence of coping style in D. cuneata, proving effective the tests applied for this identification. Two different groups were observed with specific behavioural and physiological responses that fit the proactive and reactive patterns. Furthermore, these groups showed differences in the energy metabolism of carbohydrates in basal state.
