Abstract

ABSTRAK Ikan petek (Leiognathus equula) merupakan ikan demersal yang dapat hidup di muara sungai maupun laguna pada kedalaman 10 meter sampai 60 meter. Penelitian ini bertujuan untuk menentukan tipe pola pertumbuhan ikan petek berdasarkan hubungan panjang bobotnya serta menganalisis kebugaran ikan petek. Pengambilan sampel dilakukan pada 24 Juni 2023, 23 Juli 2023, serta 19 Agustus 2023 menggunakan jaring rampus dengan panjang 36.576 meter, lebar 6.4008 meter, dan ukuran mata jaring yaitu 1 inci dan 2 inci. Hasil penelitian menunjukkan bahwa hubungan panjang bobot ikan petek yang didapatkan memiliki nilai b kurang dari 3 (2.3907) sehingga dapat dikatakan pola pertumbuhannya alometrik negatif (pertumbuhan panjang lebih cepat daripada pertumbuhan bobotnya). Hasil faktor kondisi yang didapatkan pada penelitian ini memiliki kisaran antara 0.7554 - 1.2153 dengan rata-rata 1.0082 + 0.1272 yang menandakan bahwa ikan petek pada penelitian ini memiliki bentuk tubuh agak montok.

Abstract

The high cost of commercial feed in Nirwana tilapia aquaculture leads to elevated production costs and reduced profits. As a solution, the provision of natural feed is proposed as an alternative to reduce production expenses. This study aims to compare the growth of Nirwana tilapia fed with three different natural feeds: Tubifex sp., Chironomus sp. larvae, and maggots. The experiment was conducted using a completely randomized design with three replicates for each treatment. The feeding rate was 3% of the fish’s body weight, administered three times a day. The parameters measured included absolute biomass, absolute length gain, daily growth rate (Specific Growth Rate, SGR), survival rate (SR), and water quality during the 30-day rearing period. The results showed that feeding Nirwana tilapia with Tubifex significantly increased growth compared to the control group (commercial pellets), Chironomus larvae, and maggots. The absolute biomass from Tubifex feeding was 5.23 ± 0.89 g, absolute length was 4.2 ± 7.8 cm, SGR was 1.52 ± 0.33%, and SR was 90%. The next highest growth was seen in Chironomus larvae, followed by maggots, with the control yielding the lowest results.
