Abstract

Ikan nila (Oreochromis niloticus) merupakan perikanan air tawar yang telah massif dibudidayakan. Peningkatan produksi komoditi ini telah banyak dilakukan melaui budidaya secara intensif, namun dihadapkan pada berbagai permasalahan yaitu serangan patogen yang dapat menyebabkan kematian organisme budidaya. Solusi dari permasalahan ini dapat ditanggulangi dengan pemberian imunostimulan yang bersumber dari bahan herbal ekstrak Aloe vera. Penelitian ini bertujuan untuk mengevaluasi pengaruh ekstrak lidah buaya yang dicampurkan ke dalam pakan komersial pada sintasan dan persentase hematokrit ikan nila (Oreochromis niloticus). Pemeliharaan ikan selama penelitian berlangsung selama 15 hari yang dilakukan pada akuarium bervolume 40 liter. Penelitian didesain menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan yaitu perbedaan dosis ekstrak Aloe vera dengan 3 ulangan, dosis yang digunakan adalah 0, 5, 10 dan 15 g/kg pakan. Hasil penelitian menunjukkan penambahan ekstrak Aloe vera ke dalam pakan tidak berpengaruh nyata (P>0,05) pada sintasan dan persentase hematokrit ikan nila. Namun secara deskriptif ekstrak Aloe vera pada dosis 10 g/kg pakan menunjukkan sintasan dan persentase hematokrit tertinggi ikan nila.

Abstract

One of the phases that determines the success of fish farming is the egg hatching phase. The production of good quality Tawes larvae can occur if the hatchability of  eggs is high and quality of eggs produced is good. The hatchability of eggs is relatively low at only 22% and can only produce approximately 10,000 fry, this is an important problem in the spawning process of Tawes fish in Indonesia. As an effort to increase the hatching rate of Tawes fish eggs, this is by treating the ratio of male to female broodstock differently in each hatching container. This research aims to determine the effect of comparison of the number of male and female broodstock on Tawes fish seed production and to find out how many seeds are produced by the ratio of male and female Tawes fish broodstock. The research was carried out for one month using the experimental design method. The parameters observed were the degree of egg hatching and air quality measurements, then data obtained were analyzed using a Completely Randomized Design (CRD) using SPSS 24 for Windows software. The results of the research showed that the ratio of male to female broodstock had an effect on production of Tawes fish (Barbonymus gonionotus) larvae, where the highest larvae production was obtained at a male broodstock ratio of 2: 1 female.
