Abstract

The study aimed to evaluate the combination between commercial feed and fermented tofu waste feeding for growth, survival rate and production of red Tilapia Oreochromis niloticus in pond. The study was conducted in Experimental Pond Installation of Research Institute for Coastal Aquaculture, Maros, South Sulawesi, using eight ponds with 2,500 m2 in size. Red Tilapia fingerlings (±8 cm in length) were reared for 112 days with 1 individu/m2 of stocking density. The feeding treatments were of 100% commercial feed (A), 75% commercial feed + 25% fermented tofu waste (B), 50% commercial feed + 50% fermented tofu waste (C), and 25% commercial feed + 75% fermented tofu waste (D). Feeding frequency was given twice a day using concentration 10% of biomass weight in the first month, and decreased by 3% of biomass weight in the fourth month. Experimental was designed by a completely randomized designed consisted of four treatments and two replications for each treatment. Observed variables were growth, survival rate, feed conversion ratio, production, and water quality. Present study indicated that different levels of combination of commercial feed and fermented tofu waste had significant effect on growth (P<0.05), but did not have significant effect on survival rate, production, and feed conversion ratio (P>0.05). Feeding by combination of 75% commercial feed + 25% fermented tofu waste could be utilized optimally by Tilapia. During experiment, pond water quality was in conducive condition to support the growth and survival rate of red Tilapia.

Abstract

Cultivation waste poses a severe threat to reducing environmental quality. However, the problem of low salinity cultivation waste can be overcome by converting it into plants. This research was conducted to assess the impact of salinity on the growth performance of Vannamei shrimp (Litopenaeus vannamei) and water spinach (Ipomoea aquatic Forsk) in a low-salinity aquaponic system. Floating raft system for planting water spinach. Furthermore, the role of water spinach in using N and P nutrients from the culture media of vannamei shrimp was analyzed. The experiment was carried out for 35 days, with two treatments and three repetitions, namely 5 and 10 ppt. Salinity affected the growth performance of shrimp and water spinach. Shrimp reared at 10 ppt exhibited higher growth rate, harvest size, and shrimp yield, along with lower feed conversion ratio (FCR) and water use compared to those reared at 5 ppt. Meanwhile, the performance of water spinach at 5 ppt salinity resulted in higher survival, plant height gain, root length gain, number of leaves, and yield of water spinach compared to 10 ppt salinity. The growth performance of water spinach decreased with increasing salinity, and the efficiency in reducing N and P from the 5 ppt culture media was 1.3 times higher than that of 10 ppt. Water spinach showed better results in the 5 ppt salinity media than 10 ppt, while vannamei shrimp grew at 5 ppt. Therefore, 5 ppt salinity was recommended as a suitable condition for integrated cultivation of vannamei shrimp and water spinach in low-salinity aquaponics. Both species were compatible and complemented each other’s role in developing low-salinity aquaponics.

Abstract

Blind feeding is a feed dosage of feeding shrimp cultivation that is carried out without looking at the shrimp biomass conditions for the first 30 days. The goal is to ensure that shrimp get adequate feed intake in the early stages of growth, yet blind feeding often has an impact on the decline in water quality as a result of overfeeding. The study aimed to evaluate the effect of the blind feeding method on the growth of vaname shrimp (Litopenaeus vannamei) and water quality. The treatments to be tested were the quantity of feed: (a) 123.5 kg/100,000 shrimp; (b) 148.2 kg/100,000 shrimp; (c) 172.9 kg/100,000 shrimp; (d) 197.6 kg/100,000 shrimp; and (e) 222.3 kg/100,000 shrimp. The dose range of blind feeding referred to the habits applied by the cultivators in the field. The shrimp used was PL 12 with a density of 1,000 individuals/m3, which were maintained for 30 days in an aquarium container of 50 x 40 x 30 cm or a volume of 50 liters. The feed was given four times a day at 8.00, 12.00, 16.00, and 20.00. The results of the study showed that the blind feeding feed dosage had a significant effect on the absolute growth of shrimp and total ammonia nitrogen (P < 0.05). The blind feeding treatment (c), which was 172.9 kg/100,000 shrimps, produced the best growth with a lower total ammonium nitrogen so it is recommended that it be applied in shell cultivation in the first 30 days of maintenance.
