“…Similarly, Endo and Wu ( 51 ) reviewed the use of blood glucose and cortisol as a good measure of assessing stress and fish welfare. Malini et al ( 52 ) reported increased blood glucose as a physiological response in fishes exposed to environmental disturbance. In addition, Hossain and Beveridge ( 24 ) categorized the survival and growth rate trend in a fish rearing system as a crucial determinant of production success and an unambiguous indicator of animal wellbeing in a confined environment.…”

Environmental enrichment (EE) improves the growth rate and welfare of some cultured fishes. However, most cultured fish species are raised in non-enriched housing conditions. Clarias gariepinus is an important commercial fish species, but little is known about the effect of EE on their welfare. This study examined the effect of different EE on the survival rate (SR), growth [mean weight gain (MWG), specific growth rate (SGR) and feed conversion ratio (FCR)], behavioral (feed response, aggressive acts and shoaling time) and physiological responses (blood glucose) of C. gariepinus. One hundred and twenty juveniles of C. gariepinus (31.65 ± 0.69 g) were randomly allocated at 10 fish/tank and subjected to either Plant Enriched (PE), Substratum Enriched (SE), Plant and Substratum Enriched (PSE) and Non-Enriched (NE) tanks in triplicates for 56-days. Behavioral acts were observed for 10 min twice daily, and glucose level in blood samples was evaluated. Data were checked for normality using the Shapiro-Wilk test before being analyzed with the Kruskal-Wallis test. SR and MWG were significantly higher in Clarias gariepinus exposed to SE, with no significant differences among PE, PSE and NE treatments. There was no significant difference between the SGR of PSE and NE. FCR was similar between treatments. The highest condition factor (k) was recorded in SE tanks. Duration of feed response was shorter in SE, but there was no significant difference between the feed response of C. gariepinus exposed to PE and PSE. C. gariepinus exposed to PE, SE and PSE displayed a similar frequency of aggressive acts. African catfish reared in NE (barren) tanks had the least duration of shoaling period. The experiment consistently found the highest and least glucose values in PSE and SE. In conclusion, environmentally enriched housing tanks with SE resulted in the best MWG with a reduced level of aggression in C. gariepinus under laboratory conditions. Thus, EE might be applicable to boost fish productivity on a commercial scale.

“…Blood glucose plays an essential role as an indicator of fish physiology, especially the stress response on grass carp fish [17]. Similar research has also been reported that the glucose level in fish is related to the stress response caused by some factors such as high stocking density [18], environmental disturbance [19], salinity [20], and pollutant of heavy metal [20]. Since blood glucose is often used for the stress response thus, the present experiment is also the blood glucose will be used as a parameter to describe the physiological response related to water exchange.…”

The effects of differences in water exchange on the productivity of glass eel stage in Anguilla bicolor bicolor culture

Eel, Anguilla bicolor bicolor has an economic value for export commodity. Eel farming has been developed both of home to industries scales. However, the main problem during the glass eel culture is the low survival rate, characterized by high mortality. This condition is related to the culture technique that has not been established yet, especially water quality management. The research aims to determine the best water exchange during the culture of the glass eel on the survival, growth, and blood glucose. The different percentages of water exchange as a treatment were followed A) control (without water exchange); B) 20% of water exchange; C) 40% of water exchange; and D) 60% of water exchange. The water exchange has affected the survival, growth, and blood glucose (P<0.05). The ammonia, nitrite, and nitrate values during the culture period showed that the control was higher compared to the others. The water exchange of 40% is suitable for glass eel stage culture to obtain the best survival and growth.

“…Similar plasma glucose increases as in the present study, i.e. a 3-fold increase in plasma glucose between pikeperch kept at high turbid conditions to those kept in the water of low turbidity, have been reported for a number of species studied in response to environmental stress; For example, Rastrelliger kanagurta , Lactarius lactarius , Scomberomorus Plumieri, Carangoides praeustus , Trichiurus lepturus , and Lutjanus rivulatus (202, 20, 160, 146, 136,3 and 94 mg dL −1 , respectively) when exposed to environmental stressor conditions (water temperature, DO levels and carbon dioxide concentrations) ( Malini et al, 2018 ). Basal blood glucose level of fish range between 40 and 90 mg dL −1 ( Patriche, 2009 ).…”

“…Similarly, high plasma glucose concentrations in pikeperch kept in low turbidity RAS may be related to stress (by environmental disturbance) that change the metabolism of glucose in fish. At the time of stress, insulin inactivation causes the use of glucose by stopping cells, resulting in increased glucose in the bloodstream ( Malini et al, 2018 ). Similar plasma glucose increases as in the present study, i.e.…”

There is a tendency to farm fish in low turbidity water when production takes place in the land-based recirculating aquaculture systems (RAS). However, the effect of water turbidity on stress and performance is unknown for many species cultured in RAS. The effect of different turbidity treatments as Formazine Attenuation Units (0 FAU, 15 FAU, and 38 FAU) on feed intake performance (latency, total feeding time, and total feed intake) and physiological blood stress parameters (cortisol, lactate, and glucose) in medium-sized pikeperch ((Sander lucioperca) n = 27, undetermined sex and age) of initial body weights of 508.13g ± 83 g (at FAU 0, 15 and 38, respectively) was investigated. The rearing system consisted of 9 rectangular tanks (200 L per tank). Fish were housed individually (n = 1, per tank, n replicates per treatment = 9). All tanks were connected to a recirculation system equipped with a moving bed biofilter. Feed intake in pikeperch kept at low turbidity (0 FAU) was 25% lower than pikeperch kept at high turbidity (38 FAU) (P<0.01) and also significantly (10.5%) lower compared to feed intake in pikeperch kept at intermediate turbidity (15 FAU) (P<0.01 for 0 FAU vs 15 FAU, feed intake sign. Value as the main effect is P<0.01). Pikeperch kept at low turbidity showed significantly slower feeding response (latency time) towards pellets entering the tank, shorter feeding times (both P< 0.05), and higher glucose blood concentration (73%) in contrast to pikeperch kept at highest turbidity. A reduction of 25% feed intake has obvious economic consequences for any fish farm and present data strongly emphasize the importance of considering the species-specific biology in future RAS farming.
