Abstract

High floc accumulation in intensive catfish culture will increase the bacterial consumption of oxygen and affects the dissolved oxygen in the media is relatively low then affecting the fish growth.  For control the floc accumulation is to remove the flock regularly. However, removing a large amount of floc will affect the flock's ability to control nitrogen waste in the water and the utilization of the flock as feed for fish will be minimum. The research was conducted to evaluate of floc volume levels on water quality and production performance of catfish culure in the biofloc system. The research design used a completely randomized design (CRD) with 4 treatments and 3 replications. The research treatments were floc volume level (KVF), namely (KVF) 20-40 ml/L, (KVF) 40-60 ml/L, (KVF) 60-80 ml/L and (KVF) 80-100 ml/L. The results showed that the water quality in all treatment were within the safe level for catfish. (KVF) 60-80 ml/L and 80-100 ml/L had higher survival rates of 100% (P <0.05). The growth rate in (KVF) 80-100 ml/L showed the lowest value compared of other treatments (P <0.05). (KVF) 60-80 ml/L can improve feed conversion ratio and increase protein retention by 59.17%, significantly different compared to other floc level treatment (P <0.05).

Abstract

This study was executed to resolve the argument on the growth superiority of three Nile tilapia strain such as, existing strain of Nile tilapia (ESNT), genetically improved farmed tilapia (GIFT) and sex reversed Monosex cultured in brackishwater pond and to comprehend the relationship of water physico-chemical parameters with the growth. Analogous age group of fish each weighing about 0.62±0.09 g with iso-stocking density (5ind./m2) and a culture tenure of 120 days was considered. The physico-chemical variables were at their optimal level over the entire time span of culture. However, all physico-chemical variable beyond alkalinity and ammonia showed strong positive correlation with mean fish weight. The study revealed that, weight gain by GIFT strain was nearly 25.9% and 5.10% higher than Monosex and ESNT strain, respectively. The highest final mean body weight was achieved in the GIFT strain (223±8.60 g) and there was significant difference among the strains. The highest apparent SGR of 16.85%/day was attained in the GIFT strain without significant variation across the strain. GIFT strain gave significantly (p<0.05) higher gross fish yield (9789.70 Kg ha-1) along with best feed conversion ratio (FCR) and survival, whereas they differed significantly among the three strains. The GIFT strain showed closest isomeric growth while the rest two had allotropic growth pattern. Thereby the results established that, strain difference significantly (p<0.05) impacted the growth parameters and GIFT was the best strain. Overall results greatly minimizes the controversy on growth pattern of different strains of Nile tilapia reared in brackishwater ponds, Bangladesh.

Abstract

Vibrio harveyi infection was an obstacle in shrimp culture. Meanwhile, the use of antibiotics in disease control was no longer effective, so the use of immunostimulants such as meniran leaves was the safest alternative. The purpose of this study was to determine the effect of adding different doses of meniran leaf extract (Phyllanthus niruri L.) to feed on the immune system of vannamei shrimp (Litopenaeus vannamei) which was challenged with Vibrio harveyi. This research was an experimental study using completely randomized design (CRD) consist of 5 treatments and 3 replications, namely, P1 (positive control): commercial feed + V. harveyi infection; P2 (negative control): commercial feed + 0.9% NaCl; P3: commercial feed + 0.5% Meniran leaf extract + V. harveyi infection; P4: commercial feed + 1% Meniran leaf extract + V. harveyi infection; and P5: commercial feed + 2% Meniran leaf extract + V. harveyi infection. The parameters observed were survival and immune response. Immune response analysis was carried out by counting hemocytes, phagocytic activation and total bacteria present in the shrimp intestines at the end of the study. The results of this study indicate that the addition of meniran leaf extract affects the immune system and the viability of vannamei shrimp. In conclusion, the addition of meniran extract to vannamei shrimp feed with a dose of 1% can improve the immune system and viability of vannamei shrimp against vibriosis.

Abstract

The purpose of this study was to determine the administration of Caulerpa racemosa extract in clinical sign and intestinal histopathological profile of whiteleg shrimp (Litopenaeus vannamei) after infected by Vibrio parahaemolyticus. The study was conducted using a completely randomized design (CRD) with six treatments and three replications. Shrimp were divided into six groups, two control groups without the administration of C. racemosa extract, the other four groups with the administration of C. racemosa extract with successive doses; 30 mg/kg (P1), 60 mg/kg (P2), 120 mg/kg (P3) and 240 mg/kg (P4) through feed. On the 15th day of rearing, the control group was divided into two groups: negative control (K-) was injected with PBS and then positive control (K+) and four other treatments (P1, P2, P3 and P4) were infected with V. parahaemolyticus. The results showed that intestinal damage caused by V. parahaemolyticus infection were inflammation and necrosis. The administration of C. racemosa extract had a significant effect on the histopathological profile of the whiteleg shrimp intestine. The lowest percentage of damage was found in the P4 treatment, which was 19.6% with a indication of low damage. Clinical sigs appeared at 48 hours post-infection pale hepatopancreas, empty intestines, reddened uropods and gnats. From this study, it can be concluded that the administration of C. racemosa extract to the feed at a dose of 240 mg/kg is the best dose in reducing the level of damage to the intestinal organs of whiteleg shrimp infected with V. parahaemolyticus.

Abstract

Gambusia was studied in Oubeira lake in spring 2016. A total of 100 specimens were collected in the lake. The sex ratio was F:M = 5.12: 1. The length-weight relationship was estimated for the population, with Wt = 0.0197Lt2.4451. The condition factor was calculated C=1±0.2 (for population) and a significant difference was observed between males and females. For 100 examined stomachs, the diet mainly consists of algae (N=54.96%, Pi= 166%, O=91%), followed by the mosquito larvae (N=21.52%, Pi= 65%, O=49%), detritus (N=19.2%, Pi= 58%, O=46%) and arthropods (N=4.3%, Pi= 13%, O=13%). For mosquitoes, two genus were recorded: Culiseta and Culex with 4 species: Culex pipiens, Culex theileri, Culex laticinctus and Culex antennatus. The culture experiments confirmed the important predation on mosquito larvae was observed with feeding intensity for females and males of 86 ± 12.28 % and 92 ± 8 % for the Culex larvae and 91 ± 7 and 93.66 ± 5.68 for the Culiseta larvae, respectively. No significant difference was observed between the sexes or for mosquito larvae. Our data support the idea that the introduction of mosquitofish has both negative and positive effects since this fish feeds on the most abundant food and not only on mosquitoes.

Abstract

The Diatom of Melosira sp. is one of the potential microalgae candidates for future biofuel resource due to its high lipid profile and fatty acid content, high growth rate, and a quick deposition rate. Salinity stress is one of the environmental factors affecting the growth of microalgae and their lipid content. This research was conducted to identify the response of Melosira sp. treated with different salinity levels on the cell growth rate, biomass productivity, and lipid production.  The microalgae cells were incubated for 8 days in 1 liter of F/2 growth medium with different salinity levels from 10 ppt to 35 ppt. Cell’s growth, SGR, biomass, lipid, and water quality factors were measured during incubation. This study revealed that the growth pattern of Melosira sp. cells under various salinities was customarily similar. Observation in the 35 ppt salt presenting the biomass productivity was 711.04 ± 69.38 mg.L-1 with lipid productivity which was 60.49 ± 1.72 mg.L-1. On the other hand, the observation of the lowest salt concentration displaying the biomass productivity was 316.64 ± 16.66 mg.L-1  with the lipid productivity which was 41.46 ± 6.94 mg.L-1. Hence, the results demonstrated that the lower salinity stress in 10 ppt enabled significant cell’s lipid production than the higher salinity of Melosira sp. in F/2 medium. Furthermore, lipid productivity was uncorrelation with biomass production pattern. This information may be useful in optimizing Melosira sp. lipid performance as a supporting knowledge.

Abstract

Bonylip barb (Osteochillus hasselti) is a favourite freshwater fish, especially in West Java, Indonesia.  Cultivation of bonylip barb is carried out in a conventional method; therefore, it is necessary to apply new cultivation technology, namely biofloc. The purpose of this study was to know the growth, feed efficiency, and survival rate of Bonylip barb in biofloc system cultivation (C/N ratio 10) with different stocking densities.  This research was conducted in March – July 2021, and the experiment was conducted at the Laboratory of Aquaculture, Faculty of Agriculture, Djuanda University, Bogor.  The object of research is bonylip barb seed (size 4.5 – 5.5 cm). The research design was a completely randomized design with three treatments of stocking density {A (10 fish/21 L), B (20 fish /21 L), and C (30 fish /21 L)} with four replications. Parameters observed were specific growth rate, feed efficiency, survival rate, and water quality. Furthermore, data were analyzed using analysis of variance (ANOVA) and LSD test.  The results showed that treatment A (stocking density 10 fish/21 L) had the best performance with a specific weight growth rate (2.03 ± 0.15%), feed efficiency (78.7%), and survival rate (100%). Water quality during the study was feasible for bonylip barb life. Keywords: Biofloc, Molasses, Osteochillus hasselti, Specific Growth Rate, Survival Rate

Abstract

A data acquisition system for measuring and storing dissolved oxygen levels has been implemented to monitor water quality levels in shrimp culture media using an internet-based potential redox sensor (ORP). The purpose of this study is to apply ARMS, an instrument for monitoring internet-based potential redox data (dissolved oxygen levels) in shrimp culture media in real-time to determine the condition of water quality. This system is designed using an ORP sensor that uses WIFI communication. In principle, when the ORP sensor is placed in the water in the shrimp culture media, the potential redox data will be detected by the sensor connected to the ESP8266 which processes and transmits data which is then displayed and analyzed on the smartphone interface. In this study, 9 units of shrimp culture media prototype ponds were used for observational tests. The object of observation in the pond is water quality data in the form of sediment potential redox values. At this stage of research, two processes of observation of data collection were conducted. The first process is to monitor water quality conditions on the user's smartphone display, in the form of the potential redox value of each pool measured by the ARMS instrument for 12 weeks. The second process is to compare the potential redox observation data measured by the ARMS instrument and the ORP Meter in each pool. Observation of comparative data took place during the 6th week. The sediment potential redox values for treatments 1, 2, and 3 were 69 mV, 151 mV, and 210 mV respectively. The average redox potentials in the water are in the range of 90.56 mV to -263 mV for treatment 1; 90.75 mV to -62,934 mV for treatment 2; 90.65 mV to 60.73 mV for treatment 3. This range is the measurement range from week 0 (shrimp seed stocking) to week 4. The results of the comparison of the two tools show that the accuracy of the ARMS tool is more than 95%.

Abstract

Currently, the problem of increasingly limited land availability has led to increasingly limited cultivation activities. The decreasing number of large cultivation locations requires people to be more creative in utilizing narrow locations and in saving water. Fish farming in buckets is a potential solution for aquaculture in a narrow area with more efficient use of water, easy for the community to do in their respective homes with relatively small capital, and finally able to meet the nutritional needs of the community. The purpose of this study was to determine the growth of tilapia (Oreochromis niloticus) kept in buckets using water spinach plants (Ipomoea aquatica). This research used two treatments, namely P0: control (fish farming in buckets without using plants) and P1: fish farming in buckets using plants. Parameters observed were absolute weight growth, absolute length growth, feed efficiency, and survival. The results showed that the P1 treatment resulted in an absolute weight growth of 3.44 g, an absolute length growth of 1.12 cm, feed efficiency of 93.08%, and survival of 100%. While the P0 treatment resulted in absolute weight growth of 3.92 g, absolute length growth of 1.21 cm, feed efficiency 81.75 %, and survival of 82.5%. Rearing tilapia in buckets without water spinach plants better results than using water spinach plants.
