“…A threshold of 60% saturation was selected because several freshwater fish species cease feeding below that level (Abdel‐Tawwab et al. ). We separately hypothesized that suckers could recover from hypoxic exposure within 14 d and that the magnitude of hypoxia during the 14 d prior to and including time t would be correlated with the hazard rate.…”

Mortality of Endangered Juvenile Lost River Suckers Associated with Cyanobacteria Blooms in Mesocosms in Upper Klamath Lake, Oregon

Unsustainably high mortality within the first 2 years of life prevents endangered Lost River Suckers Deltistes luxatus in Upper Klamath Lake, Oregon, from recruiting to spawning populations. Massive blooms of the cyanobacterium Aphanizomenon flos-aquae and their subsequent death and decay in the lake (bloom-crashes) are associated with high pH, low percent oxygen saturation, high total ammonia concentrations, and spikes in the cyanotoxin microcystin. Poor water quality within the lake is considered the most likely cause of juvenile sucker mortality, but mechanisms causing the high mortality are not known. We introduced PIT-tagged age-1 Lost River suckers into three continuously monitored mesocosms in Upper Klamath Lake to determine the timing of juvenile sucker mortality relative to pH, temperature, and dissolved oxygen. Mortality was inferred from a lack of movement detected on remote PIT tag detection equipment within each mesocosm. Mortality was compared among mesocosms and an indoor tank-held control group. We fitted time-varying Cox hazard models to test hypotheses about short-term and chronic effects of single

“…Fish reared at intensive and semi‐intensive culture systems have been exposed to several physical and chemical stressors such as overfeeding, handling, over‐fertilization, capture, transportation, heat stress and high stocking densities. (Abdel‐Tawwab et al, 2019; Dawood et al, 2020b). The rearing stressors are recognized as oxidative factors associated with overproduction of ROS that causes oxidative stress and deteriorate the general health condition of fish (Dawood et al, 2020c).…”

Aquatic organisms are susceptible throughout their lives to chemical and physical stressors, which negatively affect their health. Various aquatic pollutants derived from industrial effluents, overuse of some agricultural pesticides, herbicides and insecticides may cause devastating toxicological aspects of aquatic organisms and deteriorate their health and growth. They also led to oxidative stress to fish due to the stimulation of the production of reactive oxygen species. Therefore, the need for using natural antioxidants to be used as feed additives is of great importance to counteract the hazardous oxidative stress responses. The use of phytochemicals, which characterized by substantial antioxidative effects, has been raised. Lycopene is the principal carotenoid pigment found in tomatoes and their products, vegetables and red fruits. Numerous studies have recommended the use of lycopene as a powerful antioxidant to attenuate the oxidative stress responses in several fish species exposed to various toxicants or any other stress conditions. Lycopene maintains the health condition of fish by enhancing the immune and antioxidative responses. This review article aimed to elucidate the current information about the potential use of dietary lycopene for several fish species and its capability to attenuate the oxidative stress and haemato‐immunological alterations resulted from aquatic environmental pollutants and other physical stressors. Additionally, the review discusses some aspects regarding the lycopene mode of action to assess the profits that would be of importance in the aquaculture industry.

“…Hypoxia is known as dissolved oxygen (DO) level in water which is low enough to negatively affect fish behaviour, physiology, immunology and growth (Abdel‐Tawwab, Monier, Hoseinifar, & Faggio, ). This situation is very much likely to occur in today's aquaculture industry due to the high stocking densities and high feeding rates.…”

To evaluate the effects of dietary nano‐selenium (Nano‐Se) on antioxidant capacity and hypoxia tolerance of grass carp fed with high‐fat diet, experimental fishes were fed Nano‐Se supplemented diets at doses of 0 (Control), 0.3, 0.6, 0.9 and 1.2 mg/kg for 10 weeks. After feeding trial, a part of the fishes were exposed to hypoxia stress. Results showed that the survival ratio of grass carp significantly increased in 0.6 and 0.9 mg/kg Nano‐Se group, and the content of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) significantly decreased in 0.6–1.2 mg/kg Nano‐Se groups compared with the control group. In addition, dietary Nano‐Se significantly enhanced glutathione peroxidase (GPX) activity and reduced the malondialdehyde (MDA) content in fishes fed diets with 0.3 and 0.6 mg/kg Nano‐Se. Dietary Nano‐Se significantly elevated mRNA expression of GPX1 and catalase (CAT) by promoting the mRNA expression of NF‐E2‐related nuclear factor 2 (Nrf2) in the hepatopancreas. After hypoxia stress, the GPX and superoxide dismutase (SOD) activities were significantly enhanced, and the MDA content and mortality rate consequently decreased in fishes fed diets with 0.3 and 0.6 mg/kg Nano‐Se. In summary, these results suggested that optimal Nano‐Se in diet enhanced the antioxidant capacity and hypoxia tolerance of grass carp.
