<p align="center"><strong>Abstract</strong></p><p>Sea cucumber <em>Holothuria </em>sp. is a marine biota that has economic value. The rearing activity of sea cucumbers is still limited to the have bay or strait areas with relatively calm coastal. This research aimed to determine the effectiveness of two types of pen‒culture system for sea cucumber rearing to the influence of ocean waves and currents. This research was done from February to July 2017 in the coastal of Rat village, Southeast Maluku Regency. The two of cultivated containers tested were a conventional pen‒culture (treatment A) and engineered pen‒culture (treatment B). A total of 30 individuals sea cucumber seeds sized 4‒6 cm were released at each pen‒culture. Survival rate and water quality were also calculated as supporting data. Observation of endurance and clearance of pen‒culture was done every two weeks. The result of visual observation showed that conventional pen‒culture treatment A was more quickly damaged and it was more damaged compared to engineered pen-culture treatment B.Through t‒test we got T <sub>count</sub> (1.065) &lt; T<sub>table</sub> (6.313) for survival and T <sub>count</sub> (0.084) &lt; T<sub>table</sub> (1.782) for growth.

Sea cucumbers are an Indonesian fisheries export commodity. Sea cucumber populations that are endangered in nature encourage sea cucumbers to be produced through hatchery and nursery. Through nursery, it is expected that sea cucumber juveniles are stronger and can increase survival rate when stocked in growth containers or restocked. This study aims to provide better sandfish nursery techniques and local area characteristics to support hatchery activities. This study was conducted in May - July 2018 at the Hatchery CV Pesona Manir Rat, Southeast Maluku Regency. Juvenile sandfish 30-36 days old, rearing in hapa measuring 100 x 100 x 70 cm with a density of 200 individuals/hapa. In one tank rearing is placed one hapa. During rearing, 100-150% of water is changed and given one-liter Navicular sp. every day. Aeration was installed 4 points on each hapa and water quality measurement was conducted every day. At the end of the study, body length measurements and mortality calculations were conducted. The result is that sea cucumber juvenile which is maintained has absolute growth ranging from 1.98 to 2.1 cm with an average absolute growth of 2.03 cm. The average mortality obtained was 53.83% with a range of 53% - 55%. Based on the discussion it was concluded that this technique can be applied in sandfish nursery. ABSTRAKTeripang merupakan komuditi eksport perikanan Indonesia.

Eel, Anguilla bicolor bicolor has an economic value for export commodity. Eel farming has been developed both of home to industries scales. However, the main problem during the glass eel culture is the low survival rate, characterized by high mortality. This condition is related to the culture technique that has not been established yet, especially water quality management. The research aims to determine the best water exchange during the culture of the glass eel on the survival, growth, and blood glucose. The different percentages of water exchange as a treatment were followed A) control (without water exchange); B) 20% of water exchange; C) 40% of water exchange; and D) 60% of water exchange. The water exchange has affected the survival, growth, and blood glucose (P<0.05). The ammonia, nitrite, and nitrate values during the culture period showed that the control was higher compared to the others. The water exchange of 40% is suitable for glass eel stage culture to obtain the best survival and growth.

Sea cucumbers are an essential fishery resource. Therefore, effective aquaculture methods should be developed to achieve their optimal production. Sea cucumbers are susceptible to various environmental factors, one of which is water quality. Monitoring water quality based on physical and chemical parameters should be useful to the rearing system in aquaculture. In practical use, farmers usually monitor only temperature, salinity, and pH, neglecting the essential role of chemical parameters. This review focuses on and urges the monitoring of physical and chemical parameters. We explored the water quality parameters that may be crucial to the sea cucumber rearing system, including temperature, salinity, pH, dissolved oxygen, ammonia, turbidity, particulate organic matter, total nitrogen, nitrate, nitrite, ammonium, silicate, and phosphate. Furthermore, this paper presents a practical way to monitor the aquaculture or rearing system of sea cucumbers. It is suggested that temperature and salinity are the crucial physical parameters, while the essential chemical parameters are phosphate, nitrate, and ammonia.

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.
