Abstract. Mahmoud HHA, Sastranegara MH, Kusmintarsih ES. 2020. Short Communication: The lifecycle of Neocaridina denticulata and N. palmata in aquariums. Biodiversitas 21: 2396-2402. The study on the life cycle of Neocaridina spp. is important because it plays a major role in the economy and trade between countries. However, there is a lack of sufficient studies on this particular topic. One of the factors that influence Neocaridina spp. life production is its life cycle and the associated water parameters. The objectives of this study were to conduct, observe, and record the life cycle of Neocaridina denticulata and N. palmata and the associated with water parameters (temperature, pH, ammonia, nitrite, and oxygen) in the aquarium. The results showed that there was no difference in the life cycle stages between the two shrimp species. Both species reached the first sexual maturity stage of the life cycle at 75 days, with the maximum body length of the mature shrimp ranging from 2.30-3.00 cm. The eggs became larvae in 15 days, larvae reached the juvenile stage after 60 days, and the juvenile became mature in 15 days. The number of eggs was influenced by the body size of the female shrimps; smaller females produced fewer eggs. Optimal water quality varies by species and must be monitored to ensure growth and survival. The temperature range in this study was 25-28°C and the pH was 6.5-8.0. The ammonia level was in the range between 1.21 and1.72 mg/L, the nitrate was between 0.06 and 7.91 mg/L, and the oxygen was around 5.5-7.9 mg/L. All of the water quality parameters in this study are within the acceptable range for Neocardina cultivation.

Most fish farmers in Malawi culture unimproved fish strains whose growth is slow and mature while still small. Four strains of Oreochromis, namely; selectively-bred/improved O. shiranus (F8), two reciprocal F1 Oreochromis hybrids, and O. karongae as a control (mean weight 2.5 ± 0.7 g) were stocked at a density of 5fish/m2 in 9m2 hapas replicated three times, and cultured for 90 days at Bunda Fish Farm. Fish were fed twice a day with feed formulated using maize bran and soybean containing 30% crude protein throughout the experimental period. The final mean weights were significantly different (p<0.05) across the treatments whereby; hybrid O. shiranus (male) X O. karongae (female) was 12.09g, hybrid O. shiranus (female) X O. karongae (male) was 9.72g, improved O. shiranus (F8) registered 9.23g, and O. karongae was the least with 9.00g. Apparent food conversion ratio was also statistically different (p<0.05) across the treatments whereby; O. karongae was 3.63, hybrid O. shiranus (female) X O. karongae (male) was 3.25, improved O. shiranus (F8) was 3.16 and hybrid O. shiranus (male) X O. karongae (female) was lowest with 2.26. There were no significant differences on the water quality parameters across the treatments throughout the experimental period and were within the required ranges for growth and survival of tilapias fish species. The results suggest that Oreochromis hybrids may be suitable candidates for aquaculture in terms of production as they performed better than the improved O. shiranus and the control O. karongae.

This research aimed to determine the stocking density that support the best growth and survival rate of carp cultivated in aquaponic systems, and to study the water quality of carp culture with different stocking densities in aquaponic systems. The study used 12 aquaria measuring 40x40x40 cm each (water volume of 50 liters). The experimental fish are carp (Cyprinus carpio) weighing in average of 3.5 g/individual. The fish were cultivated with different stocking densities as treatment, including A = 4; B = 7; C = 10 and D = 13 individuals/aquarium. The fish were fed with pellet at 5%/body weight/day with a feeding frequency of two times a day. The study was conducted for 4 weeks. Data consisting of daily growth, survival and water quality parameters (temperature, pH, dissolved oxygen, ammonia, nitrite and nitrate) were measured once a week. The data obtained were analyzed by ANOVA. The results of the study showed that the difference in stocking density had no significant effect on the growth and survival of carp. Water quality was in a reasonable range to support the growth and survival of carp cultivated with aquaponic systems.Keywords: cultivation, carp, aquaponics, stocking density, growth

The Status

A new engineering methodology is proposed to improve the automation process in monitoring the water quality in a small scale aquaculture system. Behavioural Response Analysis using Vision Engineering Network or BRAVENet is proposed, as a support system to a traditional sensor-based system, to monitor critical water quality parameters such as temperature, pH, salinity and dissolved oxygen. BRAVENet is based on the reactions or behavioural responses of tiger prawns to different water conditions. The performance of both the sensor-based system and BRAVENet are analysed and discussed. It is shown that the BRAVENet can identify unsafe levels of water parameters and is a good monitoring and prediction tool for water conditions especially those instances when industry grade sensors fail or become erroneous. Promising results show that BRAVENet can be used as a support system, if not as a replacement, in continuously monitoring the status of the critical water quality parameters of aquaculture systems.

Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density information on tilapia seeds measuring 2-3 cm as an alternative to using tilapia (O. niloticus) seeds 7-9 cm in size so that they can be developed in Batur Lake. The research was conducted in January - March 2020 in the floating net cages in Trunyan Kintamani village, Bangli, Bali. The research used a completely randomized design method with three treatments and three repetitions. The Tilapia seeds used are 2-3 cm with different stocking densities, 100 ind/m3, 150 ind/m3, and 200 ind/m3. The parameters observed were SGR (Specific Growth Rate), absolute growth, SR (Survival Rate), FCR (Feed Conversion Ratio), and water quality including temperature, DO, pH, TDS. The results of this study indicated that stocking density did not have a significant effect on the growth and survival rate of tilapia seeds, because the temperature was too cold so that the tilapia seeds failed to adapt properly at the beginning of stocking and the physiological conditions of the fish were disturbed so that the fish experienced stress and went to died. Water quality parameters measured include temperature with a range value of 25.86-25.880C, pH with a range value of 9.08-9.13, DO (Dissolved oxygen) with a range value of 7.9-8 mg/L, and TDS (Dissolved solids) with a range value of 1040.25-1041.58 mg/L.

Ikan tambakan (Helostoma temminkii) adalah satu dari beberapa jenis spesies ikan air tawar yang ekonomis di Indonesia. Komoditas ini cukup digemari di beberapa wilayah Jawa, Sumatera, dan Kalimantan. Oleh karena itu, prospek pengembangan budidaya ikan tambakan merupakan hal yang penting. Tulisan ini bertujuan untuk mengetahui respons ketahanan ikan tambakan terhadap paparan beberapa parameter kualitas air. Seluruh kegiatan pengujian dilakukan di Balai Riset Perikanan Budidaya Air Tawar dan Penyuluhan Perikanan, Bogor. Ikan yang digunakan pada percobaan ini adalah ikan tambakan generasi kedua hasil domestikasi (panjang standar: 7,5 ± 0,28 cm; bobot: 15,2 ± 2,11 g). Uji toleransi yang dilakukan meliputi ketahanan terhadap salinitas, pH, suhu, dan oksigen terlarut. Jumlah ikan yang diuji untuk masing-masing parameter kualitas air yaitu 30 ekor pada perlakuan salinitas, pH, dan suhu, serta 40 ekor untuk pengujian toleransi terhadap oksigen terlarut dengan tiga kali ulangan pada masing-masing perlakuan. Berdasarkan data penelitian, ikan tambakan dapat bertahan hidup dan beraktivitas secara normal pada kisaran salinitas £ 10 ppt, pH 5-9, suhu 20-35oC, dan kandungan oksigen terlarut > 3 mg/L. Kisaran nilai pada parameter kualitas air di luar batas toleransi dapat berpengaruh negatif pada pertumbuhan dan sintasan ikan tambakan.Kissing gouramy (Helostoma temminkii) is one of valued freshwater fish in Indonesia. This species is quite popular in some areas of Java, Sumatra, and Kalimantan. Therefore, the development of aquaculture for this species is essential. This paper was intended to determine the response of fish resistance to the exposure of several water quality parameters. All of the experiments were carried out at the Institute for Freshwater Aquaculture Research and Fisheries Extension, Bogor. The experimental fish used in the experiment were domesticated kissing gouramy (2nd generation) with standard length of 7.5 ± 0.28 cm and total weight of 15.2 ± 2.11 g. The tests, on the resistance to salinity, pH, temperature, and dissolved oxygen. For each treatment, 30 fish were challenged with salinity, pH, and temperature treatments, and 40 fish for oxygen tolerance treatment. All treatments were conducted with three replications. Based on the results, kissing gouramy could survive and behave normally in the range of £ 10 ppt salinity, pH 5-9, temperature 20-35°C, and dissolved oxygen content of more than 3 mg/L. The range of values on water quality parameters which exceeded the tolerance limit could result in the negative effect on the growth and survival of kissing gouramy.
