Pakan alami memiliki peran penting dalam menunjang pertumbuhan, sintasan, dan penampilan warna pada budidaya ikan hias karena. Salah satunya adalah cacing grindal (Enchytraeus buchholzi) yang merupakan pakan alami potensial dengan kandungan protein tinggi. Namun rendahnya kadar karotenoid dalam tubuhnya membuat kurang optimal untuk mendukung kecerahan warna ikan. Upaya peningkatan kualitas nutrisi cacing grindal dapat dilakukan melalui pengayaan pakan kaya karotenoid, seperti wortel (Daucus carota) dan labu kuning (Cucurbita moschata). Penelitian ini bertujuan mengetahui pengaruh pemberian wortel dan labu kuning terhadap laju pertumbuhan populasi dan kandungan karotenoid cacing grindal. Pemeliharaan cacing dilaksanakan selama 20 hari menggunakan tiga perlakuan pakan, yaitu P1 (pelet komersial), P2 (wortel), dan P3 (labu kuning), masing-masing tiga ulangan. Data dianalisis menggunakan Rancangan Acak Lengkap dengan uji ANOVA taraf 95% serta uji lanjut Duncan Multiple Range Test. Hasil penelitian menunjukkan bahwa rata-rata jumlah kokon tertinggi diperoleh pada perlakuan pelet (48,97 ± 8,36 ind.), dibanding wortel (27,09 ± 4,64 ind.) dan labu kuning (31,91 ± 7,78 ind.). Jumlah cacing muda tertinggi juga terdapat pada pelet (66,82 ± 13,27 ind.), diikuti wortel (59,55 ± 10,13 ind.) dan labu kuning (61,29 ± 12,40 ind.). Jumlah cacing dewasa tertinggi diperoleh pada pelet (51,41 ± 6,22 ind.), dibandingkan wortel (46,53 ± 9,21 ind.) dan labu kuning (49,72 ± 7,89 ind.). Sedangkan kandungan total karotenoid tertinggi terdapat pada wortel (3,160 ± 0,225 µg/g), disusul labu kuning (2,013 ± 0,088 µg/g), dan terendah pada pelet (0,203 ± 0,030 µg/g). Dengan demikian, wortel dan labu kuning kurang efektif dalam mendukung produktivitas cacing grindal, namun efektif meningkatkan akumulasi karotenoid dalam tubuh cacing grindal.

Natural feed plays an important role in supporting growth, survival, and coloration in ornamental fish aquaculture. One example is the grindal worm (Enchytraeus buchholzi), a potential live feed with high protein content. However, its low carotenoid level makes it less optimal in enhancing fish coloration. Nutritional improvement of grindal worms can be achieved through feed enrichment with carotenoid-rich ingredients such as carrot (Daucus carota) and pumpkin (Cucurbita moschata). This study aimed to determine the effect of carrot and pumpkin supplementation on population growth and carotenoid content of grindal worms. The culture was conducted for 20 days with three feed treatments, namely P1 (commercial pellet), P2 (carrot), and P3 (pumpkin), each with three replications. Data were analyzed using a Completely Randomized Design with ANOVA at a 95% confidence level, followed by Duncan’s Multiple Range Test when significant differences were observed. The results showed that the highest average number of cocoons was obtained in the pellet treatment (48.97 ± 8.36 ind.), compared to carrot (27.09 ± 4.64 ind.) and pumpkin (31.91 ± 7.78 ind.). The highest number of juveniles was also found in the pellet treatment (66.82 ± 13.27 ind.), followed by carrot (59.55 ± 10.13 ind.) and pumpkin (61.29 ± 12.40 ind.). Likewise, the highest number of adults was obtained in the pellet treatment (51.41 ± 6.22 ind.), compared to carrot (46.53 ± 9.21 ind.) and pumpkin (49.72 ± 7.89 ind.). Meanwhile, the highest total carotenoid content was recorded in carrot treatment (3.160 ± 0.225 µg/g), followed by pumpkin (2.013 ± 0.088 µg/g), and the lowest in pellet (0.203 ± 0.030 µg/g). In conclusion, carrot and pumpkin were less effective in supporting grindal worm productivity but effective in enhancing carotenoid accumulation in their body.
