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.

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.

The present study was carried out to document the characteristics and to analyse the present status of ornamental fish enterprise in the Ratnagiri District of Maharashtra State. A total of 71 ornamental fish enterprises were surveyed. Ornamental fish industry of Ratnagiri District was dominated by men and majority of them belong to one religion. The ornamental fish enterprises was found to be the primary source of livelihood for these people. Maximum units were established in less than 0.01 ha land. The retail shops were small with an area of 10-20 sq. m. The major items of non-recurring expenditure were tanks, water supply and electrical items, water treatment equipments, building for housing the tanks, water quality parameter analysis equipments, aerators, blowers and hosing for aquarium tanks. Major items of recurring expenditure were dry feed, electricity charges and communication charges. Goldfish and angelfish were the most preferred groups due to the demand in market. Monsoon crops were mostly taken by ornamental breeding and rearing units. Dry feed was commonly used by the enterprise for feeding and salt as chemical for treating fish while oxytetracycline was the common antibiotic used by ornamental fish entrepreneurs. The maximum breeding and rearing unit holders were those who got trained as beneficiaries of the Rainbow Revolution Scheme (RRS) of the Marine Products Export Development Authority (MPEDA).

A study was conducted from July 2013 to June 2016 on production rate, quality, and color of pearl, cultured at Trishal, Fulbaria and BFRI (Bangladesh Fisheries Research Institute) of Mymensingh region. Freshwater pearl producing mussel, Lamellidens marginalis was used in this experiment. Eighty mussels per decimal were stocked in integration with fish culture. Three ponds from three locations were used. The area of each pond was 40 decimal having water depth of 1.5m in Trishal, Fulbaria and BFRI respectively. Water temperature, pH, Ammonia, Dissolve oxygen, Alkalinity, Ca2+ and Phytoplankton (× 103) ranged from 25.37-28.730C, 6.2-7.92, 0.02-0.3mg/l, 5.09-6.08mg/l, 100.17-191.50, 15.31-25.87and 48.99-63.45, respectively. Survival rate of the operated mussels were 30.62%, 34.62% and 40.25%, respectively. After 3 years of rearing, 53%, 76% and 93% pearls containing mussels were harvested from Trishal, Fulbaria and BFRI respectively. After final harvesting total pearl production, its quality and color were observed and found better at the location of BFRI, followed by Trishal and Fulbaria. Research study concluded that, the quality of pearl depends on intensive care, proper management, suitable water quality parameter, sunlight penetration, food availability and soil quality of the culture pond.  J Bangladesh Agril Univ 17(3): 424–429, 2019

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.
