“…Generally, under typical rearing conditions, dietary β‐glucan studies in farmed species such as the pompano ( Trachinotus ovatus ) showed higher final body weights and specific growth rates than no inclusion (Hoang et al, 2018). A decrease in temperature often leads to fish having appetite loss and a reduction in digestion rate and swimming (De Almeida et al, 2021). The dietary β‐glucan could counteract the impact of temperature on growth performance, as observed in the present study and Soltanian et al (2014) in a short‐term cold stress study on catfish.…”

The drop in temperature during the winter months can lead to a decrease in growth, induce metabolic stress, and increase mortality incidences. The present study evaluated the potential of functional feed additives in mitigating the negative impacts of winter‐rearing conditions in striped catfish (Pangasianodon hypophthalmus). Four test diets were evaluated over a twelve‐week feed trial: (1) zinc‐acetate (Zn‐acetate), (2) selenomethionine (Se‐Met), (3) β‐glucan, and (4) control with no added feed additive. The survival rate in the β‐glucan (95.00%) and Zn‐acetate (93.30%) dietary groups was higher than the control (78.30%) and Se‐Met (85.00%). Fish fed with the β‐glucan had the highest weight gain (20.75% increase), specific growth rate (13.75% increase), and lower feed conversion ratio (9.64 % decrease). However, feed additives did not influence the fatty acid profiles or whole‐body proximate composition. Although, Zn‐acetate and Se‐Met had higher body ash content. Serum cortisol and glucose levels were lower in β‐glucan and Zn‐acetate than in other treatment groups. All feed additives resulted in higher superoxide dismutase, glutathione peroxidase, and catalase activity in the liver and muscle. This study found that β‐glucan and zinc‐acetate can improve cold stress resistance and offer a sustainable strategy for catfish rearing over winter.

“…348 Collazos et al (1998) proposed that the number of fish erythrocytes was mainly affected by water temperature and increased at higher water temperatures, with higher numbers in summer than in winter. 349 Regarding the direct effects of season and temperature on RBC parameters, some scholars have proposed that the main external cause of seasonal variation of RBC and haemoglobin content is dissolved oxygen in water rather than temperature. 350 The changes in RBC number and haemoglobin level were negatively correlated with dissolved oxygen in water, which is a normal physiological compensatory response of fish to adapt to environments with different levels of oxygen.…”

Farmed fish are a promising source of high-quality and sustainable protein. However, the production of farmed fish products that meet food safety standards is one of the major public health challenges worldwide. Therefore, food safety management in fish farms has recently garnered increasing attention. However, the detection of health parameters in fish is currently lacking. Haematology, an approach that is widely used in humans, provides a reliable assessment of health status in a non-lethal and lowcost way. Nevertheless, comprehensive, systemic and standard haematological parameters have not yet been established in farmed fish. Here, we provide a summary of the recent advancements in haematology health indicators in fish. Generally, haematological parameters are based on physiological and biochemical indices in blood. After a global review of haematology in fish, we analysed the research progress and current trends in haematology indicators in farmed fish, and explored their potential application for healthy farming. Furthermore, we discuss the internal and external environmental factors that also affect blood physiological and biochemical indices. Finally, we discuss the trends and future challenges for the application of haematology in fish. Collectively, the topics discussed in this review highlight the predictive and severely underrated value of haematological parameters in fish farming.
