“…Likewise, by allowing an understanding of how organisms respond to different environmental situations and their trade-offs that may relate to the capability of a population to thrive under those conditions [ 49 , 62 , 63 ], biomarkers may further provide important information about how species will cope in an introduced environment and how they will compete with native species for a given niche, under a current or changing environment, and potential adaptation and spread, disclosing potential invasive setups [ 58 , 64 , 65 ]. Also, and regarding biological invasions, studies have been reported on the impacts of the invasive species on native species biomarker endpoints which may lead to a community impairment and invasion success, as in the case of Asparagopsis armata , a red seaweed producing halogenated compounds and releasing them into the environment and with ecosystem impacts [ 34 ], namely survival, and also reported impacts on macrofauna energetic biomarkers [ 40 ], and oxidative stress and damage, neurotoxic effects, and inflammation and immune responses [ 34 ], limiting the number of foraging herbivores and creating a thriving environment for this species and modulating the landscape and biodiversity.…”

Endpoints assessed at the population or community level are most often the result of the sum of effects on individuals, arising from the effects at the cellular and molecular levels. Within this framework, these lower biological level endpoints are more responsive at an early stage of exposure, making them potential toolboxes to be used as early-warning markers to address stress. Given this, by linking responses and understanding organisms’ metabolism and physiology, the possibilities for the use of biomarkers in stress biology are vast. Here, biomarker comprehensive examples are given to enlighten the need to link levels of biological organization, and their usefulness for a myriad of fields and applications is presented and discussed.

Legal restrictions and consumer trends are contributing to the growing movement for fish welfare. Therefore, the aquaculture sector is a means of reducing animal stress and enhancing physiological state, which raises financial profits. Feed additives have therefore been suggested as possible dietary stress alleviation. In this trend, a 75-day feeding trial was conducted to evaluate the effects of three organic acids (formic acid (FA), lactic acid (LA), and commercial organic acids mix (COM)) as dietary additives in Nile tilapia (Oreochromis niloticus) reared under a stressful condition (unchanged water). Fish (weighing 3.95 ± 0.05 g) were randomly housed into eight groups (n = 210 fish/group; 70 fish/replicate; 3 replicates/group). The first (negative control) and second (positive control) groups were fed a basal diet without additives and with water exchange at 20% of the water volume every 2 days for the first group and without water exchange for the second. The other six groups (FA1, FA2, LA1, LA2, COM1, and COM2) were fed basal diets supplemented with OAs at two doses (1 and 2%) without water exchange during the trial. The results revealed that fish kept without water exchange (positive control) had the highest level of water-unionized ammonia and nitrite and a marked decline in growth performance (weight gain and specific growth rate). The unchanged water induced substantial decreases in the hematological profile (white and red blood cell count, hemoglobin value, and hematocrit %), protein profile indices (total protein, albumin, and globulin), and antioxidant-immune response (superoxide dismutase, catalase, lysozyme, and total immunoglobulin M). In addition, the biochemical indices (glucose, creatinine, urea, alanine aminotransferase, and aspartate aminotransferase) and lipid peroxide (malondialdehyde) were substantially increased in the positive control group. In addition to that, marked and severe histopathological alteration in the gills, liver, and intestine including hyperplasia, hemorrhage, and degenerative and necrotic changes that were associated with desquamation and sloughing were obvious in the PC group. Dietary LA1 significantly enhanced (P < 0.05) the overall measured indices; meanwhile, the dietary FA and COM recorded the worst results. Overall, our findings demonstrate that the unchanged water negatively affected the growth and physiological functions of Nile tilapia. Dietary incorporation of organic acids did not protect the fish from these hazards except the LA (1%). The latter can reduce nitrogenous compounds, enhance immune response, and alleviate these alterations for the sustainable aquaculture industry.
