GROWTH AND COLOUR PERFORMANCE OF THE CROSSBREED MARBLE STRAIN Betta splendens AND Betta imbellis

Abstract

Betta ornamental fish of marble strain is a strain which is prefered by the hobbyists, because of its unique color, expensive price, and difficult to obtain the fish color strains. Therefore strain marble betta fish is still dominant for export quality for national and international contests. The aim of this study was to observe the growth and color performance of the crossedbreed marble strains of wild betta, Betta imbellis crossed with Betta splendens. The hybrids of B. imbellis (f) x B. splendens (m) (D) had a specific length and weight rate, (1,113 ± 0.04%/day; 2,531 ± 0.14%/day; 26.61 ± 2.02 mm) which was better than that of the hybrids B. imbellis (m) x B. splendens (f) (C) (1,099 ± 0.02%/day; 2,244 ± 0.13%/day; 25.97 ± 1.33 mm; and 0.0027 ± 0.0003 mm). However, the survival rate of the C hybrids (42.19 ± 11.42%) was higher than those of D (33.67%-17.08%). Based on the obtained results of the color identification the hybrids had as many as 15 characters of color, homozygous strains of marble which became the target of as much as 1%.

Aplikasi Kontrol Kualitas Air dan Pakan Untuk Peningkatan Produktivitas Budidaya Betta Fish

“…Oleh karena itu perlu adanya penjaminan mutu untuk meningkatkan kualitas air dan produksi ikan dengan cara memanfaatkan kemajuan teknologi dalam pemantauan dan teknologi otomasi [5]. Parameter fisik yang perlu diperhatikan adalah suhu, kedalaman kolam, tingkat kekeruhan, TDS atau padatan terlarut [6]. Parameter kimia yang perlu dikendalikan adalah karbondioksia, pH, nitrat, fisffat dan amonia [7].…”

Next-generation sequencing yields complete mitochondrial genome assembly of peaceful betta fish, Betta imbellis (Teleostei: Osphronemidae)

“…belonging to the family Osphronemidae (Panijpan et al 2014). The bubble-nesting species Betta imbellis, also known as the peaceful betta, is native to SEA and one of the most popular wild type betta fish for fishkeeping hobbyists (Kusrini et al 2015). This betta fish inhabits still and sluggish waters including rice paddies, swamps, roadside ditches, streams, and ponds.…”
