Abstract

The  feed plays a critical role in the success of freshwater lobster cultivation, but it often presents challenges due to its relatively high cost, accounting for up to 60% of production expenses. To address this issue, farmers in Sukabumi have devised various alternative feeds by harnessing different protein sources to reduce the expenditure on commercial pellets. One such innovation is a moist feed composed of a blend of pellets, cassava, and snails in a ratio of 1:1:1.4. However, there hasn't been prior testing of its nutritional content. Consequently, this study aims to evaluate the nutritional composition of this moist feed and assess its impact on the growth of freshwater lobsters as well as water quality. For this research, a total of 300 lobsters, ranging in size from 7 to 10 grams, were reared in fiberglass tanks. The lobsters were fed twice daily. The proximate analysis of the cassava and snail-based moist feed revealed protein content (20.52%), fat (2.61%), carbohydrates (12.87%), moisture content (50.64%), and ash content (13.36%). The lobsters exhibited a growth rate of 0.3% per day, and the water quality remained favorable, with parameters such as temperature (23-25°C), pH (6.5-7), dissolved oxygen (5-7 mg/L), nitrate (1.907 mg/L), nitrite (0.141 mg/L), ammonia (0.442 mg/L), phosphate (0.032 mg/L), and alkalinity (237.4 mg CaCO3/L) within acceptable ranges. These findings suggest that the moist feed provided by farmers lacks sufficient protein content to fully meet the nutritional requirements of lobsters, resulting in slower growth. On the other hand, water quality remains conducive for successful lobster farming.

Abstract

Asnan Ridoanrisna. Efficiency Of Pakcoy Plants (Brassica Rapa) In Maintaining Water Quality To Support The Survival Rate Of Tilapia. Under Guidance By Robin And Novita Mz. Tilapia is a freshwater fish commodity with high economic value. According to data from the Central Bureau of Statistics (BPS), tilapia exports reached 12.29 thousand tons with a value of USD 78.44 million. Tilapia farming faces the risk of mortality which can lead to economic losses, one of which is caused by organic pollution. To address this issue, this research employs phytoremediation methods with varying plant densities to improve water quality and tilapia survival. The study was conducted with four treatments: A75 (plant density 75% of the aquarium surface area), A50 (50%), A25 (25%), and A0 (no plants), using an aquarium size of 60 x 30 x 50 cm³. Each treatment received chicken manure at 1.8 grams per aquarium and 40 tilapia fish per aquarium. Observations were made over 15 days in March 2023, measuring physical and chemical water parameters including DO, pH, TDS, temperature, and ammonia, as well as calculating the survival rate of tilapia. Using a Completely Randomized Design (CRD), the study found that treatment A75 achieved the highest survival rate at 62.5%. This result indicates that higher plant density in the phytoremediation method is more effective in maintaining water quality and supporting tilapia survival.

Abstract

Galah shrimp is one type of freshwater shrimp that has great potential for cultivation. One of the obstacles to the growth of king prawns is water quality. This study was conducted to determine the effect of the installation of Vegetable Floating Raft (VFR) on the growth of king prawns (Macrobrachium rosenbergii). This study was conducted using the t-test method, with control and Vegetable Floating Raft treatments. The results showed that the growth pattern of weight and length of king prawns in each treatment was relatively the same. However, the daily weight growth rate of king prawns in the control treatment was greater at 3.36%, compared to the treatment of Vegetable floating raft at 1.26%, while the daily length growth rate of king prawns in the control treatment was 0.86%. The daily length growth rate in the Vegetable floating raft treatment was smaller at 0.61%. During the study the value of the degree of survival of the control treatment was 95%, while in the treatment of Vegetable floating raft the percentage of the degree of survival of king prawns was 62%. Based on the results of visual observations seen the rest of the feed and the rest of the skin during molting. It is suspected that shrimp are stressed due to changes in water quality characterized by increased ammonia levels in the last maintenance week caused by the death of kale plants in the maintenance medium.

Abstract

Changes that occur in aquaculture are influenced by feeding and water quality, causing changes in the composition, abundance, and structure of plankton communities. Therefore, the presence of plankton can be used as an indicator of aquaculture. The purpose of this study was to analyze the structure of plankton communities in freshwater crayfish farming in fiber ponds. For plankton retrieval techniques in this study were carried out every day at 06.00 for 14 days. A total of 50 liters of water is taken from each pond using a bucket, water collection in each pond is carried out at 5 different points and filtered using planktonet. The types of phytoplankton found in 3 fiber ponds consist of classes Bacillariophyceae, Chlorophyceae, Cyanophycae and Rotifers and consist of 13 species. This type of zooplankton consists of the class of rotifers and consists of 25 genera. The type of phytoplankton that most often dominates is found in Microc species. In zooplankton, the type that most often dominates is Branchiaonus. This makes Microcystis. and Branchiaonus. plays a high role in maintaining the sustainability of the ecosystem in fiber ponds. H' values range from 1.2 - 1.5 for E values range from 0.4 - 0.5 and D ranges from 0.3 - 0.5. This shows that the quality of LAT cultivation water is still relatively poor. It is characterized by low diversity and uniformity of plankton and indications of species dominance.

Abstract

Land and water sources are important in cultivation activities. Efforts to overcome the problem of limited land and water for cultivation include technology development. One of the technologies being developed is vertiqua. The Vertiqua that has been developed, both with and without biophysical filters, still has weaknesses, namely high levels of ammonia. Therefore, a biofical modification was carried out, namely using a biofical top filter to increase the effectiveness of reducing ammonia levels to support fish growth in the vertiqua. The aim of this research was to test the effectiveness of the biofical top filter on the rate of reduction in ammonia levels in the vertiqua. The research design was carried out using a Completely Randomized Design (CRD) for one treatment with three repetitions, in this study with an upper biophysical filter as treatment and three vertiquas as repetitions. The data analysis carried out in this research was an experimental method. The results of the research are presented in the form of graphs, tables and narratives using Microsoft Word and Excel. As for testing, the research sample was tested with the middle value using Microsoft Excel and Minitab 21 by comparing the test results with the standard. According to the research results, the use of an upper biophysical filter can have an effect on maintaining physical and chemical water quality parameters (P<0.05) so that they comply with quality standards. However, there are several water quality parameters that do not comply with quality standards, such as pH and nitrite. The use of the upper biophysical filter type in the vertiqua koi fish cultivation system has an effect on reducing ammonia and maintaining water quality so that it meets quality standards. However, the nitrite value at the beginning was high, but after two weeks of testing the value began to decrease, indicating that the upper biofical filter was running optimally.

Abstract

The zooplankton community structure in koi fish (Cyprinus rubrofuscus) aquaculture using the Vertiqua system with a biological biofilter was analyzed to understand the crucial role of zooplankton as an integral part of aquatic ecosystems. Zooplankton, which connects phytoplankton with carnivorous consumers, also serves as an effective biological indicator for assessing changes in aquatic environmental conditions. This study employed a descriptive method to observe the abundance and diversity of zooplankton in three Vertiqua ponds. The observations revealed that the zooplankton groups Rotifera and Ciliophora were dominant, with abundances of 118 Ind/l and 106 Ind/l, respectively. The three observed Vertiqua ponds were categorized as mesotrophic, with an average diversity index of 2.2, zooplankton evenness index of 0.7, and dominance index of 0.2. Measurements of the water’s physical-chemical factors showed an average temperature of 26°C, pH 6, DO 6 Mg/l, ammonia 0.05 Mg/l, nitrite 2.33 Mg/l, nitrate 14.6 Mg/l, and phosphate 1.1 Mg/l. Based on the abundance and diversity of zooplankton found, the pond water conditions can be categorized as mesotrophic with a moderate level of fertility, supporting a varied zooplankton community structure.

Abstract

The high mortality in crayfish shipping transportation activities is due to the high level of stress during transportation. The handling that needs to be considered is when harvesting and transporting the fry. Poor seed transportation can result in stress to high mortality. Transportation of live crayfish can be done in two ways, namely with a wet system using water and a dry system without using water media. Research to maintain mortality begins with packing procedures starting from placing ice cubes in plastic that has been wrapped in newspaper in each 500ml seteroafoam and then inserting 22 crayfish in each box and then allowed to stand with a predetermined deadline. The first treatment survival rate reached 97% of 66 mortalities of 2 tails, in the second treatment 94% of 66 mortalities of 4 tails, the third treatment 80%, of 66 mortalities of 9 tails. Based on the results of the study, the addition of ice cubes to the packing media for crayfish with living conditions resulted in an average survival rate of 90.3% with the shortest deadline of 30 hours and the longest of 40 hours, thus it can be said that the packing media with the addition of ice cubes has an impact on the survival rate of crayfish.

Abstract

The growth of comet fish (Carassius auratus) in the vertiqua system using a biofical filter is motivated by limited land and water which can cause low water quality to affect the growth rate of fish. The utilization of technology needs to be done to overcome these problems and the technology used is vertiqua. Previous research showed that comet fish in the vertiqua system produced slow growth rates and had high ammonia levels. Therefore, vertiqua was modified in the filter section to become a biofical filter. The purpose of this research is to test the effectiveness of comet fish growth in the vertiqua system using a biofical filter. The benefits of this research are that the vertiqua system using a biofical filter can be a solution to overcome the problem of limited land and water, become a support for system cultivation innovation, and become a reference for further research. This research method uses descriptive methods, observation and interviews. The comet fish used in the study were 3-4 cm in size. The results of this study indicate that the vertiqua system using a biofical filter is still not effective in supporting fish growth. The growth rate of comet fish in the vertiqua system is significantly different from that in the soil pond and the growth rate of comet fish in the vertiqua system is lower than that of comet fish in the soil pond. Ammonia value is relatively high from the quality standard (>0.05). However, this system is able to maintain good fish survival and good water quality, especially in temperature, pH, and DO.
