Gracllaria sp. merupakan rumput laut yang memiliki nilai ekonomis tinggi karena menghasilkan agar. Agar banyak dimanfaatkan dalam bidang industri maupun pangan. Kualitas Gracilaria sp. ditentukan oleh kadar agar, pigmen serta  proksimatnya. Penelitian ini bertujuan untuk mengkaji pengaruh parameter kualitas media tumbuh Gracilaria sp. terhadap biosintesis agar, klorofil a, karoten dan kadar proksimat (protein, karbohidrat, lemak, abu, dan air). Lokasi pengambilan sampel di reservoir dan biofilter tambak udang Vaname (Litopenaeus vannamei). Kondisi lingkungan perairan yang diukur adalah kandungan nitrat dan fosfat, suhu air, salinitas, DO (oksigen terlarut), serta pH (Derajat keasaman). Ekstraksi agar dilakukan dengan metode alkali. Karakterisasi agar menggunakan analisis Fourier Transform Infra Red. Hasil penelitian menunjukkan kandungan agar (31,4 ± 0,42%) pada reservoir lebih baik dibandingkan biofilter. Begitu pula dengan konsentrasi klorofil a (19,61 ± 0,04 mg/g), karotenoid (7,42 ± 0,21 µmol/g) serta kadar protein (15,38 ± 0,27%). Kadar lemak, karbohidrat, air dan abu pada kedua lokasi tidak berbeda nyata. Hasil karakterisasi agar menujukkan keberadaan gugus galaktosa 3,6-anhydro-L-galaktosa. Gracilaria sp. is well known as to has a high economically value, due to the application of the agar content that is used in various industries especially in food industry. The quality of Gracilaria sp. depends on agar and pigment content as well as proximate analysis. This study aimed to investigate the effect of water quality parameter on Gracilaria sp habitats to agar, chlorophyl a, carotene and proximate analysis (protein, carbohydrate, total lipid, ash, water content). Samples were collected from reservoir and biofilter from Litopenaeus vannamei’s waste pond. Water quality parameter measured were nitrate and phosphate, water temperature, salinity, dissolved oxygen (DO) and pH. Agar extraction was done by alkali methods. Agar and its chemical structure were characterized by FT-IR analysis. Results showed that agar content (31.4 ± 0.42%) on reservoir was better than biofilter. Higher results from reservoir samples were also found in chlorophyl a (19.61 ± 0.04 mg/g), carotenoids (7.42 ± 0.21 µmol/g) and protein level (15.38 ± 0.27 %). On the other hand, total lipid, carbohydrate, water and ash content were similar. Based on FT-IR analysis shows that the galactose 3,6-anhydro-L-galactose was present.

Rapid industrialization around riverside without having proper environmental consideration causes severe water pollution in our country. On accordance with the consecution of this problem the study was conducted to investigate the water quality of Narai canal and Balu river during January to June, 2012. Water quality parameter analysis i.e. color, odor, pH, total dissolved solids (TDS), dissolved oxygen (DO), ammonium (NH4) results show that except pH all exceeded standard limit for domestic water use, irrigation and fish cultivation. The minimum and maximum values of pH, TDS, DO and NH4 were 6.89-7.33, 982-1308 ppm, 0.33-2.12 ppm and 6.79-89.76 ppm, respectively. Present analysis with secondary research data also revealed that this pollution rate is becoming intensified quickly which may pose a great threat in future for human health, ecosystem and sustainable agricultural production. So, Effluent Treatment Plants (ETP) is urgently needed to minimize the concentration of pollutants and ultimately to save the river water of the concerned area.J. Bangladesh Agril.

This paper presents the results of investigation on water quality in Ninh Binh coastal area in 2015. The results show that the risk quotient of water quality of the area was 0.34, indicating the water was safe for aquatic life. However, for individual water quality parameter, the coastal water of Ninh Binh was contaminated by TSS, ammonium and arsenic; water faced the risk of deficiency of dissolved oxygen. The remaining water quality parameters (nitrite, phosphate, cyanide, oil and grease, coliform, Cu, Pb, Zn, Cd, Hg and organochlorinated pesticides) are safe for aquatic life. As spatial distribution, the concentration of pollutants in water is lower at depth > 15 m. In the rainy season, the water quality tends to decrease compared to the dry season.

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.
