Ikan gurame merupakan organisme omnivora yang mendiami perairan tenang seperti rawa, situ dan danau. penelitian ini bertujuan untuk mengetahui pengaruh penggunaan biji karet yang telah difermentasikan pada pakan terhadap pertumbuhan dan kelangsungan hidup ikan gurame dengan memberi pakan campuran fermentasi biji karet. penelitian ini dilakukan di balai benih ikan bungus kota padang pada januari 2022februari 2022 menggunakan metoda rancangan acak lengkap dengan 4 perlakuan dan 4 kali ulangan. hasil penelitian menunjukkan bahwa perlakuan terbaik berada pada perlakuan b dengan penambahan tepung biji karet yang sudah difermentasi sebanyak 30% sehingga nilai pertambahan bobot mutlak sebesar (3,55 g), panjang mutlak (1,52 cm), survival rate (100%), specific growth rate (3,10%), feed convertion ration (0,19) dan efisiensi pakan (51,03%). perlakuan terendah berada pada perlakuan d dimana penambahan fermentasi tepung biji karet sebanyak 50% sehingga berpengaruh buruk terhadap laju pertumbuhan benih ikan gurame. kata kunci : ikan gurame, benih, fermentasi, biji karet.

Carp is an omnivorous organism that inhabits calm water sich as swamps, lakes. This study aims to determine the effect of using fermented rubber seeds in feed on the growth and survival of carp by feeding a mixture of fermented rubber seeds. The research was conducted bungus fish seed center, padang city in January-February 2022 using the completely Randomized Design method with 4 treatments and 4 replications. The result showed that the best treatment was in treatment B with the addition of rubber seed flour that had been fermented as much as 30% so that the absolute weight gain value was (3,55 g), Survival Rate (1,52 cm), Survival Rate (100%), Specific Growth Rate (3,10%), Feed Convertion Ration (0,19) and feed efficiency (51,03%). The lowest treatment was in treatment D where the addition of rubber seed flour fermentation was as much as 50% so that it had a bad effect on the growth rate of carp seed.
