The Cantang Grouper (Epinephelus fuscoguttatus-lanceoulatus) is a mating of the female Tiger Grouper fish (Epinephelus fuscoguttatus) and the male Kertang grouper fish (Epinephelus lanceoulatus). However, in farming activities, the Cantang Grouper fish can be affected by a VNN infection. One way to deal with the VNN infection is by giving recombinant nano-vaccine from the microalga Chlorella Vulgaris. This study aims to determine the effect of recombinant nano-vaccine administration of the microalgae Chlorella Vulgaris on the growth of the fish weight, length, and eye tissue in the Cantang grouper fish (Epinephelus fuscoguttatus lanceolatus) infected with Viral Nervous Necrosis (VNN). The method used in this study is experimental. The test results showed that the administration of the recombinant C. vulgaris (p-PerCv) vaccine affected the growth in length and weight of the Cantang grouper, this was because the growth in length and weight of its from the treatment group was significantly different from the control group (0.039<0.05). Known by the ANOVA test and also has a different effect on the level of damage to eye tissue both damage to hypertrophy, vacuolization, and necrosis. The results of the Tukey test showed that the treatment that had a significant effect was the T1 treatment (treatment of healthy fish +33l of recombinant C. vulgaris vaccine (p-PerCv) +8.5l of Chitosan nanoparticles). © 2024 Author(s).
