Delonix regia is commonly called Flamboyant or flame of the forest. The seeds were fermented, boiled, sundried and then ground into powdered meal. 40% crude protein based test diets containing Delonix regia seed meal D0 = 0%; D15 = 15%; D20 = 20% and D25 = 25% inclusion levels respectively were prepared. Red tilapia (Oreochromis niloticus) fingerlings of 6 weeks old were acclimatized for two weeks and then stocked in 12 hapas at 15 fish per hapa measuring 0.6 m × 1.2 m × 0.7 m placed in a concrete tank. Each diet was assigned to fish in a separate hapa in triplicate and administered at 3% fish body weight per day for 16 weeks. Fish weight and length were taken initially, bi-weekly and terminally. Water quality was monitored weekly. Number of fish at the end was recorded and survival rate, growth, feed utilization, fillet yield and blood parameters were determined. The data were subjected to the analysis of variance and mean separation (P= 0.05). Survival rate was highest in fish raised on D20 and least in D25 without any significant difference across the range. Mean growth performances, feed utilization indices and fillet yield were generally congruent between D20 and D25 with varying degrees of significant difference to other feeds. Results of blood assay did not depict harmful effects of the test diets indicating that the fish enjoyed some good measures of health. The gross performance of fish on D20 was optimal. It was therefore concluded that 20% dietary inclusion level of fermented, cooked and dried flamboyant seed was the best for the red tilapia (Oreochromis niloticus) post fingerlings.

Abstract Red tilapia is kind of freshwater culture fish is quite popular because it has several advantages compared with other types of freshwater fish. To fullfil the demand of red tilapia can be overcome by cultivation. Effort to increase the production of red tilapia is to improve the quality of feed. The purpose of this study was to try the effect of the use of sword bean seed meal on the growth rate, survival rate and feed efficiency of red tilapia. The research method is experimental with completely randomized design (CRD) with five treatments and four replications. The treatments used were: (A) sword beans seed meal at 0% and soybean meal by 50%, (B) 10% sword beans seed meal and 40% soybean meal, (C) 20% sword beans seed meal and 30% soybean meal, (D) 30% sword beans seed meal and 20% soybean meal and (E) 40% sword beans seed meal and 10% soybean meal. The main parameters that measured were growth, survival rate and feed efficiency. Secondary parameters measured were water quality. Analysis of the data using analysis of variance (ANOVA) and to know the difference between treatments using Duncan's Multiple Range Test. Results showed the administration of sword bean seed meal on feed rations provide a significantly different effect (p<0.05) on the growth and feed efficiency but not significantly on survival rate of red tilapia (p>0.05 ). Highest daily growth rate obtained on treatment B on feed containing 10% of sword bean meal (1.20 %) was significantly different than treatment A (1.02 %), C (0.88 %) , D (0.85 %) and E (0.75 %) . Lowest daily growth rate was treatment E that significantly different with treatment A and B but not significantly different with treatments C and D. Highest feed efficiency obtained on treatment B (30.29 %) was not significantly different than treatment A (27.56 %), C (25.95 %) and D (27.78 %). Lowest feed efficiency was treatment E (17.84 %) significantly different than treatment B. Subtitution of sword bean seed meal in feed rations gave result that was not significantly different effect on the level of survival of red tilapia. Water quality of red tilapia rearing media was temperature range between 25-28° C, pH 7-8, dissolved oxygen 2-5 mg/L and ammonia 1.5 to 3.0 mg/L.

Tilapia is a popular fish for consumers and aquaculture in every part of Thailand. This study was conducted to determine the level of mineral supplementation in the diet for the growth of red tilapia fingerlings, which gave the lower fish production cost. The fingerlings with an initial average weight of 3.1 ± 0.48 g and a length of 2.5±0.24 cm were raised in 3 m3 concrete tank with 1.5 m3 of water volume at 20 fish/m2 stocking density. Fish were fed with pellets diet (28 % crude protein), which contained different levels of mineral supplements (0 (control), 20 and 40 g/Kg) in triplicate replications. The experiment was conducted within 80 days. The results showed that fish fed with diet3 had better average daily weight gain (ADG) and food conversion ratio (FCR) than diet2 and diet1 significantly (P<0.05). The ADG and FCR of fish fed with diet3 showed 0.70 ± 0.02, 1.72 ± 0.02 respectively, but there was a non-significant difference in survival rate from all treatments (P>0.05), and the fish production cost of diet 3 is lower than those in diet1 and diet2. Thus, this experiment concluded that minerals supplementation at the level 40 g/kg diet were suitable for tilapia aquaculture.

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.

Organic and inorganic pollutants such as N, P, and heavy metals are a serious problem in water bodies (lake, reservoir, river, and stream) and have deleterious effects to pond productivity and human health. These pollutants produced from anthropogenic activities (i.e. industrial, agricultural, and settlement) are released into the water bodies and causing poor water quality. Constructed wetland (CW) is one of the technologies that have the capability to solve such problems. The purpose of this experiment was to examine the efficiency of constructed wetland in terms of reducing pollutants from the stream as a water resource for aquaculture area and increasing fish production. Two kinds of treatments were set up: one fish pond culture with constructed wetland and the other one without constructed wetland (control). Each treatment consisted of three replications. The result showed that water quality in the fish pond with CW was better than the control. Constructed wetland were able to reduce ammonia (NH3-N), nitrite (NO2-N), nitrate (NO3-N), TN, phosphate (PO4-P), TP, Cu, Pb, and As concentrations to 15.00%-88.27%, 9.52%-72.73%, 11.11%-57.14%, 20%-66.67%, 24.44%-80.77%, 12.04%-77.95%, 50.00%-100%, 56.25%-100%, and 46.83%-100%, respectively. Nile tilapia cultured in pond using CW was higher than the control in terms of total length, body weight, and survival rate. The t test revealed that nile tilapia (Oreochromis niloticus) cultured in pond with CW and the control has significant difference (P<0.01) in terms of total length, body weight, and survival rate. This is the evidence that constructed wetland technology is very useful on improving water quality and increasing pond productivity of nile tilapia cultured in the freshwaterpond.

 Abstract. Hidayati D, Nurtjahyani SD, Oktafitria D, Ashuri NM, Kurniallah W. 2019. Short Communication: Evaluation of water quality and survival rate of red tilapia (Oreochromis niloticus) by using rice-fish culture system in quarry land of clay. Biodiversitas 20: 589-594. Quarry land is an area that has been used as mining land and has different characteristics from the former conditions before being mined so that the level of productivity of the soil decreases. This study aims to determine the suitability of clay quarry land in Tuban as a cultivation medium based on the analysis of the water quality and survival rate of red tilapia (Oreochromis niloticus) using rice-fish culture system. This study used a completely randomized experimental design method with triplicate of three ratio of cultivation medium using Ex-mining Land Soil (EmLS) from quarry land and Top Soil, i.e., 1:0 (A), 1:1 (B), and 0:1 (C/Control). Results of water quality measurements that include nitrite, nitrate, temperature, pH, and dissolved oxygen in descriptive unreal influence showed good condition. However, ammonia gives a significantly different effect mainly on the survival rate in 30 days nurture. In the end, the ANOVA test result of tilapia survival in treatment A was not significantly different (P>0.05) with treatment B and control. Based on these data, it can be seen that the EmLS from the quarry land of clay and TS can be used as a medium for cultivation of red tilapia (O. niloticus) with the recommended ratio of 1:1.
