Penelitian ini bertujuan untuk mengetahui pertumbuhan dan perkembangan larva R.lateristriata yang diberi pakan mikrokapsul maggot Black Soldier Fly. Penelitian telah dilaksanakan pada bulan Februari-Agustus 2024 menggunakan metode eksperimental dengan rancangan percobaan berupa Rancangan Acak Lengkap (RAL) yang terdiri dari lima perlakuan dan setiap perlakuan terdiri dari lima ulangan. Perlakuan terdiri dari (P0) :  D0, (P1) : D0 mikrokapsul, (P2) : mikrokapsul maggot instar 4, (P3) : mikrokapsul maggot instar 5, dan (P4)  mikrokapsul maggot instar 6. Variabel meliputi pertumbuhan dan perkembangan morfoanatomi larva ikan dianalisis ragam One Way Anova pada tingkat signifikasi 95%. Hasil berbeda nyata dilakukan uji lanjut Tukey. Data hubungan panjang tubuh dan CFRE dianalisis uji korelasi. Data mengenai perkembangan morfoanatomi bukaan mulut dan sirip meliputi pigmentasi dan bentuk dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa pemberian pakan mikrokapsul maggot BSF instar 6 (P4) memberikan pengaruh paling baik terhadap pertumbuhan dan perkembangan larva. Pemberian pakan mikrokapsul instar 6 (P4) menghasilkan pertambahan bobot sebesar 0,033±0,012 g, pertambahan panjang sebesar 9,58±0,25 mm, RGR 1,109±943,1%, SGR 8,10±2,29%. Uji korelasi menunjukkan jumlah CFRE berhubungan positif (R=0,9970 ) dengan panjang tubuh larva. Pakan mikrokapsul maggot BSF tidak berpengaruh nyata terhadap FCR dan SR. Ditemukan adanya pigmentasi melanofor dan xantofor pada larva. Pemberian pakan mikrokapsul maggot Black Soldier Fly instar 6 menghasilkan pertumbuhan dan perkembangan larva R.lateristriata paling optimal dibandingkan perlakuan lainnya. Dengan demikian, penggunaan mikrokapsul maggot BSF dapat digunakan sebagai subsitusi pakan komersial selama pemeliharaan larva ikan R.lateristriata.

This study aimed to investigate the growth and development of R. lateristriata larvae that were fed with BSF maggot microcapsules.The research was conducted in February-August 2024 using an experimental method with a Completely Randomized Design (CRD) experimental design consisting of five treatments and each treatment consisted of five replicates. The treatments consisted of (P0) which is D0 feed; (P1) which is microcapsule D0 feed; (P2) which is forth instar maggot microcapsule feed; (P3): which is fifth instar maggot microcapsule feed, and (P4) which is sixth instar maggot microcapsule feed. Variables include the growth and development of morphoanatomy of fish larvae were analyzed by One Way Anova at the 95% significance level. This research result were significantly different, Tukey's further test was conducted. Data on the relationship between body length and CFRE were analyzed by correlation tests. Data on the development of morphoanatomy of mouth openings and fins including pigmentation and shape were analyzed descriptively.
	The results showed that sixth instar maggot microcapsule feeding (P4) gave the best effect on growth and development of larvae. Sixth instar maggot microcapsule feeding (P4) resulted in weight gain of 0.033 ± 0.012 g, length gain of 9.58 ± 0.25 mm, RGR of     1,109±943.1%, SGR 8.10±2.29%.The correlation test showed that the number of CFRE was positively correlated (R=0.9970) with larvae body length. Feeding of maggot BSF microcapsules has no significant effect on FCR and SR. It was found that there was melanophore and xanthophore pigmentation in the larvae. Feeding Black Soldier Fly maggot resulted in better growth and development of R.lateristriata larvae compared to others instar and commercial feed with the optimal treatment of maggot microcapsule feed instar 6. Thus, the use of BSF maggot microcapsules can be used as a substitute for commercial feed during the rearing of R. lateristriata fish larvae
