Shrimp farming with a non-partial harvest system is a cultivation concept to obtain optimal production harvest. The purpose of this study was to determine the business feasibility status of vaname shrimp (L. vannamei) cultivation with a non-partial harvesting system in terms of the ecological and financial aspects from aquaculture. The research method used in this study is a survey research method with data collection techniques based on purposive sampling. The results showed, this non-partial system is ecologically very feasible, because the conditions of the average daily water quality parameter values (DO, pH, temperature, salinity) during the aquaculture period are still above the water quality standard threshold for intensive aquaculture. The business financial feasibility analysis resulted in a profit of IDR 441,307,102,-, BEP Unit 2,062 Kg, BEP Sales IDR 119,995,253,-, R/C of 1.71, Return on Investment of 47.69%, and Payback Period of 2.7 years. Meanwhile based on investment analysis, the Net Present Value of IDR 34,136,139,245,-, Net B/C 11.61, and Internal Rate of Return 37.23%. So, it can be denied, that based on ecological aspects and economic multiplication of aquaculture systems like this can be categorized as very feasible and profitable to be globally developed.

The highly use of polyethylene plastics in Indonesia has negative impact toward freshwater aquaculture systems. Omnivorous fish is one of the freshwater biota that exposed by microplastics. This study aims to determine the effect of microplastics to water quality and the prevalence of microplastic exposure in tilapia. The experimental design is conducted using a microplastic exposure (polyethylene scrub) with concentration of 0.01 g/L (P1), 0.1 g/L (P2), and 1 g/L (P3). Each treatment is repeated 3 times. The organ groups observed are the gastrointestinal, liver, gills, and gonads. The stages of the research including fish raising, microplastic extraction, water quality measuring parameter, and counting the amount of microplastics. The result obtained for water quality parameter is temperature, pH, and dissolved oxygen still within safe fish farming limit. Microplastics at high concentration in water can cause a decrease in the total value of ammonia and do not affect the value of water temperature, pH, and dissolved oxygen. Microplastics are found in the digestive organs, liver, gills, and gonads. The digestive tract of tilapia is the organ with the most microplastics after 14 days of exposure. It is concluded that microplastic is harmful for the life of tilapia because it can absorb to the liver and gonads.

Mangrove is one of the coastal ecosystem is able to grow in fluctuating water conditions. Mangrove areas are found on the Nusa Lembongan island, Bali, is a ??mangrove ecosystem that have the unique characteristics of water area. The mangrove area is located on one of the small islands in Bali that have no source of freshwater input and there is the entrance of water into the mangrove forest. The uniqueness of waters in mangrove ecosystem will affect the type and density of fauna associated, particularly mollusca. Mollusca are one of the animals that live and thrive in the mangrove ecosystem. Therefore, it is necessary to study which aimed to provide a description of the water quality and mollusca on mangrove ecosystem in Nusa Lembongan. This research was conducted in June 2015 on a six station observation. Measurement of water quality conducted on four water parameters such as temperature, DO, pH, and salinity. Observation on the type and density of mollusca done using transects squared (1 x 1 meter). The range of values ??obtained water quality parameters, such as; 1) salinity (32.00-34.33 ppm), 2) pH (7.06-7.96), 3) temperature (27.27-30.13 Celsius), and 4) DO (2.60-6.90 mg/l). Water quality parameter values ??obtained are still in the range of water quality standard and suitable place to live and grow for marine biota life. Dissolved oxygen (DO) value was still below the threshold quality standard. There six families of mollusca found in six observation station, such as Neritidae, Littorinidae, Columbellidae, Olividae, Carditidae, Muricidae, Potamidae, Certthiidae. The highest density was in Family Potamidae (1.83 ind/m2), so the Family Potamidae is able to adapt and have a wide area deployment.

Nine runoff containment basins (RCBs), used directly or indirectly for irrigating plants in ornamental plant nurseries, and one adjacent stream were sampled for water quality between Feb. and July 2013 in Maryland (MD), Mississippi (MS), and Virginia (VA). Triplicate water samples were taken monthly. Analysis was done for 18 water quality variables including nitrate-nitrogen (NO3−-N) and ammonium-nitrogen (NH4+-N), orthophosphate-phosphorus (PO4-P) and total-phosphorus (T-P), potassium, calcium, magnesium, sulfur, aluminum, boron (B), copper (Cu), iron (Fe), manganese, zinc (Zn), pH, total alkalinity (T-Alk), electrical conductivity (EC), and sodium. Additionally, 15 RCBs from 10 nurseries in Alabama (AL), Louisiana (LA), and MS were sampled in 2014 and 2016. Most prevalent correlations (P = 0.01) were between macronutrients, EC, B, Fe, and Zn, but none were prevalent across a majority of RCBs. Water quality parameter values were mostly present at low to preferred levels in all 25 waterways. Macronutrient levels were highest for a RCB that receives fertility from fertigation derived runoff. Water pH ranged from acidic to alkaline (>8). Results of this study show water quality in RCBs can be suitable for promoting plant health in ornamental plant nurseries, but also shows levels will vary between individual RCBs, therefore demonstrates need to verify water quality from individual water sources.

Mangrove forest is tropical coastal vegetation that grow on muddy and sandy soils which affected by sea tides. One of important commercial species that live in mangrove ecosystem is the mud crab (Scylla serrata). Feed and water quality have been considered as critical components for supporting the growth both of weight and carapace length of this species. This study was conducted from January to February 2017 in the area of ??Ecotourism Kampung Kepiting, Bali. The influence of different natural feed such as Jerbung shrimp (Penaeus merguiensis), Mollusca, lemuru fish (Sardinella lemuru) and sea worms (Nereis sp.) on the growth performance of the mud crab were investigated. Water quality parameter data such as pH, DO, temperature, salinity and ammonium were also collected. The obtained data were analyzed by using variance analysis of Statistical Product and Service Solutions (SPSS) version 21. The result showed that the use of different types of feed have no effect on  the length of carapace, but it has significantly influence on  the specific growth rate of mud crab. Finally, different types of the given feeding were still resulted in the save range of water quality parameters for mud crab culture.
