Gambaran Darah Dan Aspek Fisiologis Ikan Mas (Cyprinus Carpio) Yang Diberi Pakan Mengandung Jamu Fermentasi Dan Dipelihara Pada Salinitas Berbeda

Common carp (Cyprinus carpio) is a freshwater fish that is widely
cultivated and consumed in Indonesia. To fill the need of that fish, the culture of
the fish need to be improved and it can be conducted by culturing the fish in empty
brackish ponds. As common fish is a freshwater fish, rearing it in brackish water
may increase the stress level of the fish. By providing the fish with pellets
enriched with fermented herbs, the stress levels might be reduced and it is
reflected in the blood profile and physiological aspects of the fish.
A study purposes to understand the blood profile and physiological
aspects of Cyprinus carpio feed with a single dosage of fermented herbs enriched
pellets (200 mL/kg feed), and raised in different salinities was conducted in June
to August 2022, at the Laboratory of Fish Diseases and Parasites, Faculty of
Fisheries and Marine Science, University of Riau. Information obtained from this
research may be used as a basis to improve the productivity of common carp
culture in saline media.
There was a one-factor Completely Randomized Design (CRD), consisting
of five treatment and three replications. The treatment applied was the salinity
level: 0 ppt (P0, control), 3 ppt (P1), 6 ppt (P2), 9 ppt (P3) and 12 ppt (P4). The
fish used is common carp (C. carpio) fingerlings 6-8 cm TL that were reared for
60 days in aquaria, 20 fishes/ aquarium or 1 fish/3L. The feed used was FF-999
pellets (35% protein content), 10% of fish biomass/day that was mixed with
fermented herbs solution just before being provided to the fish. The feed was given
three times a day, namely at 08.00 AM, 13.00PM and 18.00 PM. Samplings were
conducted three times, before the treatment, in the 30th day, and in the 60th day.
Parameters measured were blood profile (total erythrocytes, leukocytes,
hemoglobin and hematocrit levels), serum biochemistry (calcium and
magnesium), physiological conditions (blood glucose, osmolarity, growth and
survival) and histopathology of gills and kidneys.
Results shown that addition of fermented herbs in fish feed pellets affcets
the blood profile and the fish physiology in general. The blood condition of fish
reared in 6 ppt and fermented herbs enriched pellets alost normal with total
erythrocytes 2.28 x 106 cells/mm3, hematocrit 31.67%, haemoglobin 9.87 g/dL,
and total leukocytes 6.80 x 104 cells/mm3. While the physiological aspects of that
fish was as follows: glucose 48.33 mg/dL, osmolarity 265 mOsm/kg H2O, blood
calcium 10 mg/dL, blood magnesium 3.3 mg/dL. In this treatment the absolute
weight growth was 10.52 g and the survival rate was 100%. The structure of
tissue in fish of this treatment shown light abnormality such as epithelium lifting,
epithelium rupture in the gill and hemorrhagic, pigmentation, and glomerular
damaged in kidneys.
Key Words : Epihtelium lifting, osmolarity, glucose, hematocrit
