Tilapia is an important commodity for Indonesian fisheries. Therefore, tilapia cultivation continues to grow. The goal is to meet market needs and increase production more optimally. One of them is through feed innovation to increase growth and maximum survival. This study aimed to explore the effect of giving vitamin premix with different doses on the growth and survival of saline tilapia (Oreochromis niloticus) fry. The method used is an experiment with a completely randomized design (CRD) which consists of 4 treatments with three replications. Treatment A (without added vitamins), B (vitamin premix 3%), C (vitamin premix 4%), D (vitamin premix 5%). The results showed that treatment D had a significant effect on increasing the weight and length of saline tilapia with an average weight value of 3.21 and an average length value of 2.67, followed by treatment C weight with a value of 2.50 and a length of 2, 05, treatment B was heavy with a value of 2.49, and length of 1.86 and treatment A was heavy with a value of 1.60, and length of 1.23. The highest survival was in treatment D with a value of 100%, treatment C with a value of 93.3%, treatment B with 86.7%, and treatment A with 80.0%. Vitamin premix dose D gave the best effect, so it has the potential to be applied in saline tilapia cultivation.
Kondisi Danau Limboto semakin kritis ditunjukan oleh luasan dan kedalaman danau yang terus berkurang. Ikan Manggabai (Glossogobius giuris) merupakan salah satu ikan endemik Danau Limboto yang memiliki ciri yang unik dan khas. Penelitian morfometrik meristic Ikan Manggabai (Glossogobius giuris) bertujuan dalam rangka upaya pelestarian Ikan Lokal Danau Limboto berbasis DNA Barcode. Penelitian ini dilaksanakan pada bulan Agustus - September tahun 2022. Ikan sampel diambil dari Danau Limboto dan dianalisis secara insitu dan ex-situ. Analisis hubungan Panjang dan berat mengikuti persamaan W = a L. Hubungan panjang dan jumlah sirip ikan Manggabai menggunakan uji korelasi dengan melihat hubungan variabel bebas atau X (panjang) dan variabel terikat atau Y (jumlah jari-jari sirip). Aspek morfometrik meristic Manggabai (Glossogobius giuri) berdasarkan pola pertumbuhan panjang dan berat menunjukkan alometrik negative (b<3). Hasil perhitungan meristic menunjukkan jumlah jari-jari pada sirip yatiu DI. VI; DII. 7-12; A. 7-10; V. I.6-11; P. 10-18; C. 14-21 dan terdiri dari jari-jari keras dan lunak. Hasil uji korelasi pertumbuhan panjang dan jumlah jari-jari pada sirip ikan manggbai menunjukkan korelasi yang lemah hingga sangat lemah. Gambaran parameter kualitas perairan masih tergolong dalam kategori sedang untuk kelangsungan hidup ikan.
