Abstract

Cultivating duckweed in aquaculture effluent offers a viable approach to eliminating contaminants. The duckweed biomass obtained can be utilized for the generation of bioenergy. However, elevated levels of ammonium (NH4+) in aquaculture effluent, combined with variations in light intensity, can hinder biomass formation. The precise mechanisms underlying this inhibition remain incompletely elucidated. The study assessed the efficacy of duckweed (Lemna perpusilla) as a treatment agent for wastewater from catfish farms. The objective was to evaluate the growth response of duckweed and its efficacy in reducing ammonium levels. The research demonstrated that daily light intensity fluctuated using shade nets and that the ammonium concentration of aquaculture wastewater varied according to the age of the fish. The shade nets, which blocked 25% of the sunlight and had an average daily light intensity of 3433.34–15199.56 lux, demonstrated a slightly elevated NH4+ removal efficiency and duckweed productivity of 69.34% and 0.050 kg/m²/day, respectively. However, these values were not statistically significant when compared to conditions without shade nets, which had a removal efficiency of 63.97% and duckweed productivity of 0.042kg/m2/day (P<0.05). The implementation of shade structures that effectively decrease solar exposure by 25% shows promise for enhancing duckweed productivity and optimizing nutrient reduction in wastewater from fish cultivation systems. This approach contributes to the promotion of sustainable integrated aquaculture.

Abstract

Nitrogen and phosphorus in a water culture are derived from the metabolism of the farmed organism, feed residue and microbial activity in the water. One way of controlling water quality due to waste in the form of nitrogen and phosphorus from aquaculture is to utilize filter feeder organisms of Anadonta woodiana Lea. This study aimed to analysis the effectiveness of the absorption of nitrogen and phosphorus in waters by A. woodiana as filter feeder. A total of 0 (control), five, ten, and 15 gravestone were putted into a tank of 35 L of water derived from Cirata reservoir. Each treatment was given three times repetition. Measurement of total nitrogen and phosphorus in gravestones were performed at baseline and end of treatment. In addition, measurement of total nitrogen and phosphorus in the water tank was measured every ten days. Another measurement is the length and weight of gravestone. Direct observations made on gravestones barnacle survival, pH, dissolved oxygen, temperature, and turbidity every day. Aeration was provided in each aquarium. Based on the results obtained, the survival of gravestone in the density of five gravestones was 93.33%, in ten gravestones density was 90%, while in 15 gravestones was 95%. The percentage reduction in total nitrogen in the water at the end of treatment was 57% for the five gravestones density, and for ten gravestones was 88.2%. The decrease of total phosphorus in water in ten gravestones density was 37.4%, whereas the increase in density of 15 gravestones and total phosphorus water percentage was 26.9%. On the density of ten gravestones, the body weight decreased until to 3.3%, while in the density of 15 gravestones decreased until to 2.5% on day 30. Results of water quality analysis showed that the DO values decreased from baseline to end of treatment (from 5.08 to 4.86 mg/L), the average water temperature from 26.5 to 27.4 °C, pH values 7‒8, and highest turbidity values was obtained in the density of five gravestone. Decrease in the percentage of total nitrogen in the water suggested nitrogen and phosphorus have been absorbted for barnacle growth.

Abstract

Transportation of fish fry with high density in closed system will reduce levels of O2, increasing CO2 and NH3, will also elevate the fish stress so that increase fish mortality. To reduce the effects of increased CO2 and NH3 can be applied by using zeolite and activated charcoal, while to reduce the fish stress is through the addition of salt. This study aims to determine the dose of salt added into the water containing zeolite and activated charcoal in a closed transportation system with a high fry density for 72 hours. The study was conducted two stages, namely the preliminary study and the primary study. The preliminary study involved the observation of the survival rate of fish fry during fasting, oxygen consumption rate of fish fry, the rate of total ammonia nitrogen (TAN) excretion of fish fry, and the adsorption capacity of TAN by zeolite and activated charcoal. In the primary study, fry transport simulations was carried out for 72 hours in the laboratory. Gourami fry (body length of 4 cm and body weight of 1.7 g) with the fry density of 50 fish/L were placed in the packing bag which has been filled with zeolite as much as 20 g/L and activated charcoal as much as 10 g/L. The study used a completely randomized design with five treatments and two replications: A: blank (without zeolite, activated charcoal, and salt), B: control (20 g/L zeolite+10 g/L activated charcoal), C: 20 g/L zeolite+10 g/L activated charcoal and 1 g/L salt, D: 20 g/L zeolite+10 g/L activated charcoal and 3 g/L of salt, and E: 20 g/ L zeolite+10 g/L activated charcoal and 5 g/L salt. The results of preliminary study showed that the survival rate of fish fry was 100% and active swimming for five days without food, the level of oxygen consumption as much as 1340.28 mgO2, produce NH3 as much as 22.64 mg/L, while zeolite and activated charcoal adsorbs >50% of TAN in time of 120 seconds. In the primary study, the survival rate of fish fry during the 72-hour transportation for treatments A, B, C, D, and E, were 0%, 57%, 59%, 65% and 74%, respectively. Treatment E with survival rate of 74% was obtained at NH3 concentration of 0.016±0.069 mg/L and CO2 as high as 89.89 mg/L while the DO of 4.26 mg/L. The highest growth and survival rate of fry for 17 days post-transportation was treatment E, accounting to 2.95% and 100%, respectively.Keywords: zeolite, active charcoal, closed system transportation, survival rate, gourami fish

Abstract

ABSTRACTGrowth rate of pearl goldfish juvenile Carassius auratus relatively slow to reach market size which will take approximately three months. To accelerate its growth can be done by providing exposure of the fish to low-power electric fields (10 V) via 3 ppt salinity water, with the goal of providing the close isoosmotic conditions, and also to streamline the flow of electricity from the electrodes to the body of the fish. This study aims to calculate the survival and growth rate of pearl goldfish juvenile of S sizes (2‒4 cm of body length) which were maintained at 3 ppt salinity water and treated by different exposure time of electric field (zero, two, four, and six minutes before feeding) with 10 volt electric power. Fish were cultured at a density of 2 fish/L in the (20×30×20 cm3) aquaria in volume of 6 L of water. Test fish had an average body length of 4.11±0.05 cm and the average body weight of 2.89±0.05 g. Exposure time of electric field were zero, two, four, and six minutes before the fish are fed, performed every day as much as three times i.e. morning, afternoon, and evening. The research design used was completely randomized design with four treatments, namely 0, 2, 4, and 6 (time for exposure is zero/control, two, four, and six minute) with three replications. The results show test fishes exposed to 10 volt electrical field for zero, two, four, and six minutes, have no significant effect on survival rate (P>0.05). For growth performance, four minute exposure treatment gives the best results compared to controls (P<0.05), supported by an increase in the percentage of the ratio of gut length to body length of the fish and higher feed efficiency.Keywords: long exposure to the electric field, growth performance, pearl goldfishABSTRAKPertumbuhan benih ikan hias maskoki mutiara Carassius auratus relatif lambat, karena untuk mencapai ukuran jual memerlukan waktu sekitar tiga bulan.
