Abstract

This study aimed to determine the growth rate and protein content in Nannochloropsis oculata, Chlorella vulgaris, Spirulina platensis were cultured using agricultural fertilizers. The agricultural fertilizers used were Urea, ZA and TSP. Each single cell protein was cultured using the three types of fertilizers with a ratio of Urea: ZA and TSP as follows (A) 1: 2: 1 [(10:20:10 g / L)], (B) 2: 2: 1 [(20:20:10 g / L)] and (C) 3: 2: 1 [(30:20:10 g / L)], respectively. The results showed that the best ratio of Urea, ZA and TSP fertilizers to growth of Spirulina, Nannochloropsis oculata and Chlorella vulgaris was C [30:20:10 (g / L)] treatment. However, phyto-protein content in Nannochlorophsis differed significantly between fertilization treatments, C fertilization yielded the highest protein content (28.75±0.05%), when compared with A (25.13±0.01%) and B (25.14±0.02%), respectively. In Chlorella vulgaris, all fertilization treatments showed very significant differences, B fertilization (28.24%±00.006) yielded the highest phyto-protein content, if compared to A (23.63% ± 0.003) and C (19.74% ±0.006 ), respectively. All fertilization treatments showed very significant differences (P <0.05) on Spirulina platensis. The highest content of phyto-protein (62.68 + 0.05%) was present in treatment C, when compared to A (52.18 + 0.05%) and B (62.37 + 0.01%) treatments, respectively.

Abstract

The observation was conducted to study the yolk absorption activity andmorphological development on the initial state of senggaringan (catfish) fishlarvae. Larvae used for this research were from the artificial spawning ofbroodstock, reared in fiber tank. The result showed that newly hatched larvae has3.02 mm ±0.14 total length and 1.1202 mm3 yolk volume. During yolk absorptionperiod, organogenesis development and length added also occurred. Larvaedevelopment occurred after hacthing involved the eye spot (23 hours, 1 minute),mouth opening (25 hours, 21 minutes) and pigmentation (50 hours, 5 minutes),.Organogenesis development and the total length increment improve, following theincrease of yolk absorption rate.

Abstract

Durian leaves have been used extensively to aid in the anesthetic process in various types of fish. The purpose of this study was to determine the immotilization capacity and stress response and survival of Tilapia under anesthesia. The RAL study design (4x4) was carried out with the durian leaf infusion treatment at concentrations of 2%, 4%, 6% and 8%. The fastest induction and sedation times were at 8% and 6% concentrations, which were 12.33 minutes and 13.35 minutes, respectively. The highest survival rate was at a concentration of 2% which reached 100%. Blood glucose levels increased due to anesthesia, ranging from 67.75 to 134.25 mg/dL
