Striped Catfish

Koto Masjid Village is the largest production center in striped catfish fish farming activities in Riau Province. One of the inhibiting factors is the disease caused by bacteria, this study aims to determine the types of pathogenic bacteria that have the potential to infect striped catfish. This research was conducted in August - November 2019, samples of striped catfish used in the study amounted to 15 tails with an average length of 15-25 cm taken from 5 ponds in Kampung II, Koto Masjid Village, XIII Koto Kampar Subdistrict, and then identified bacteria by Conventional Laboratory in Fish Parasites and Diseases, Faculty of Fisheries and Marine, Riau University, Pekanbaru. This study uses a survey method that is by taking samples from the field in Pu and then the isolation of bacteria is carried out from the kidney organ in the TSB media then purified on the TSA media. The results of the study found 3 types of pathogenic bacteria namely Aeromonas sp., Edwardsiella sp., and Pseudomonas sp. Water quality during the study was pH 6.6-70, DO 4.05-4.35 mg/L, NH3 0.035-0.2 mg/L and Temperature 28-300C.

ABSTRACT: Aquaculture also known as fish farming is one of the methods for breeding rearing and harvesting of freshwater and marine species of fish and shellfish, in ponds, rivers, lakes and oceans. In this article an attempt has been put forth to study and apply techniques that could help in improving the water quality in aquaculture ponds and to further understand the role played by enzymes and probiotics by means of bio remedial procedures and protocols. Aquaculture productivity needs to be improved to cater the ever-increasing demand, no doubt, but simultaneously a proactive role for environment protection is required. The gathering of organic wastes worsens the water quality and reduces the level of dissolved oxygen in the fish aquaculture ponds. This further increases the formation of toxic metabolites such as ammonia (NH3), nitrite (NO2-) and hydrogen sulphide (H2S). Hence, NH4+ or NO3- removal processes (nitrification and denitrification) become essential for the pond water quality. This can be carried out by applying different types of nitrifying and denitrifying bacteria such as Nitrosomonas, Nitrobacter and Alcaligenes. In the present investigation, 2 earthen ponds were selected from Ponnagi near Eluru in Krishna district, Andhra Pradesh, India. One pond (Pond A) was treated with probiotics having Nitrosomonas, Nitrobacter and Alcaligenes sps. And the other pond (Pond B) was kept as control. During the culture period, the water samples were collected from probiotics treated and control ponds for analysis of water quality parameters. The current study is aimed to focus on the changes in water quality and biochemical characterization of bacterial isolates from water samples of Ponnagi area in probiotic treated ponds and to compare the results with ponds not treated with probiotics.

AbstractThis study aimed to determine the quality of drinking water supplied in different types of food stalls in Jashore Municipality, Bangladesh. A total of 35 water samples were collected from different tea stalls, street side fast food stalls, normal restaurants and well-furnished restaurants. The water quality was evaluated by determining the distinct physical, chemical and biological parameters. The results revealed that the water used in the food stalls and restaurants for drinking purpose was in desired quality in terms of turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), sulfate (SO42−), phosphate (PO43−), chloride (Cl−), sodium (Na) and potassium (K) concentrations. The values were within the permissible limit proposed by the Bangladesh Bureau of Statistics and the World Health Organization. Concentrations of calcium (Ca) and magnesium (Mg) found in several samples were higher than the World Health Organization standard. Iron (Fe) concentrations were higher than the permissible limit of the World Health Organization. Only 46% exceeded the permissible limit of Bangladesh Bureau Statistics. The threatening result was that the samples were contaminated by fecal coliform, indicating that the people of Jashore Municipality may have a greater chance of being affected by pathogenic bacteria. The drinking water provided in the street side fast food stalls was biologically contaminated. The findings demonstrate that the drinking water used in food stalls and restaurants of Jashore Municipality did not meet up the potable drinking water quality standards and therefore was detrimental to public health.

Aquaculture Water

In a fish farm, the water quality is important to ensure fish growth and farm productivity. However, the study of the quality of water using in aquaculture has been ignored until now. Although there are several methods to treat water, nanomaterials have not yet been applied for indoor fish farming because it may difficult to supply a sufficient amount of water, and the operating parameters have not been developed for recirculating aquaculture systems. Nanotechnology can be applied to treat water, specifically through adsorption and filtration, to produce drinking water from surface water and to treat wastewater by processing a high volume of effluent. The adsorption and filtration of seawater has also progressed to allow for desalination of seawater, and this is recognized as a necessary tool for extended treatment protocols of various types of seawater. This study investigated the treatment of aquaculture water using nano-porous adsorbents (e.g., pumice stone) to control the contaminants in seawater in order to maintain the water quality required for aquaculture. The results are used to derive an analytical relationship between the ionic species in aquaculture water, and this provides empirical parameters for a batch reactor for aquaculture. The quality of the influent and effluent for aquaculture is compared using time-series analyses to evaluate the reduction rate of ionic components and thus suggest the optimum condition for fish farming using bioreactor processes.

Tiger grouper is a marine aquaculture commodities that has good prospects to be developed. One of the areas that could potentially be used as a place of tiger grouper fish farming is the Tegal Island, Pesawaran. The purpose of this research was to analyze the level of water quality for fish farming tiger grouper (Epinephelus fuscoguttatus). This research was carried out in March-May 2017 descriptive analytic nature by doing the observations on the quality of waters which include physical and chemical parameters. The data that used in this research sourced from primary data about the suitability waters of the island while the secondary data is form in research location maps. There were 4 sampling stations which determined with global positioning system (GPS). The results showed that the water quality which is owned by the island's waters on station 1, 2, 3 and 4 were in the quite appropriate category for the cultivation of tiger grouper.
