“…Because the fish diseases are the most important factor limiting fish production and affect the profitability of fish breeding and incubation enterprises. It is also necessary to pay attention to the fight against diseases in order to develop this sector in a sustainable way (Subasinghe, D. Soto, & Jia, 2009;Bondad-Reantaso et al, 2005;Hanol Bektas, Ucar, & Savaser, 2017). Correct and effective protection efforts will prevent incidence of fish diseases and increase the productivity of the industry.…”

In this study the effect of black cumin seed (Nigella sativa) on nonspecific defense mechanisms of rainbow trout (Oncorhynchus mykiss) was investigated. The percentage of black cumin seed in diet were 0.0; 0.5; 1.0; 2.5; 5.0; 10.0 and 20.0 g/kg respectively. Rainbow trout (O. mykiss) of initial weights 108.7±17g were used for experiment. The biometric measurements and the blood parameters were determined in each group after feeding 7, 15, 25, 40 and 60 days respectively. In 7 day experiment, plasma protein, MCH, MCHC, RDW_SD and RDW_CV, MPV values at 1.0 and 2.5 g/kg dose groups differed favorably from the control group. In 15 day feeding experiment, there is a positive mathematical difference in almost all parameters in the 2.5 g/kg dose group compared to control group. In 25 day experiment, there is a positive mathematical difference according to control group in almost all parameters and statistically significant difference between MCH and MPV values in the 2.5 g/kg dose group (P<0.05). In 40 day feeding experiment, plasma protein, MCV, RDW_CV, PLT values differed positively from the control group at the 1.0 and 2.5 g/kg dose groups and mathematical differences were observed in other parameters. In 60 day feeding experiment, at the doses of 1.0 and 2.5 g/kg, many parameters differ from the control group and from the other groups.

Bacterial infections in marine fishes are linked to mass mortality issues; hence, rapid detection of an infection can contribute to achieving a faster diagnosis using point-of-care testing. There has been substantial interest in identifying diagnostic biomarkers that can be detected in major organs to predict bacterial infections. Aspartate was identified as an important biomarker for bacterial infection diagnosis in olive flounder (Paralichthys olivaceus) fish. To determine aspartate levels, an amperometric biosensor was designed based on bi-enzymes, namely, glutamate oxidase (GluOx) and aspartate transaminase (AST), which were physisorbed on copolymer reduced graphene oxide (P-rGO), referred to as enzyme nanosheets (GluOx-ASTENs). The GluOx-ASTENs were drop casted onto a Prussian blue electrodeposited screen-printed carbon electrode (PB/SPCE). The proposed biosensor was optimized by operating variables including the enzyme loading amount, coreactant (α-ketoglutarate) concentration, and pH. Under optimal conditions, the biosensor displayed the maximum current responses within 10 s at the low applied potential of −0.10 V vs. the internal Ag/AgCl reference. The biosensor exhibited a linear response from 1.0 to 2.0 mM of aspartate concentrations with a sensitivity of 0.8 µA mM−1 cm−2 and a lower detection limit of approximately 500 µM. Moreover, the biosensor possessed high reproducibility, good selectivity, and efficient storage stability.
