Komposisi plankton pada perairan terutama pada tambak udang Vannamei dapat berperan sebagai parameter ekologi perairan selain sebagai pakan alami dan penghasil oksigen. Sistem resirkulasi merupakan salah satu cara untuk menjaga kualitas air yang nantinya mampu mendukung komposisi plankton yang seimbang sehingga budidaya udang vannamei super intensif dapat berjalan optimal. Microbubble merupakan suatu alat yang berfungsi menghasilkan gelembung udara dalam air denga ukuran diameter kurang dari 200 µm. Gelembung mikro ini mampu meningkatkan kadar oksigen terlarut sehingga dapat menurunkan kadar ammonia dalam air budidaya sampai 95%. Penelitian yang dilakukan merupakan penilitian eksperimental yang dirancang dengan menggunakan dua kolam bundar dengan diameter 3 m. Satu kolam bundar menngunakan aerator dan yang lain menggunakan Microbubble untuk sistem aerasinya. Jenis Plankton diamati menggunakan mikroskop. Dari hasil penelitian tersebut Genus plankton yang mendominasi adalah Chlorophyta dengan nilai 88,%, Cyanophyta 8,%, dan Chrysophyta 2,7%. Jenis Chlorophyta meliputi Chlorella, Nanochloropsis, dan Oocystis. Penggunaan Microbubble mampu meningkatkan kelarutan oksigen, dari hasil penelitian nilai DO yang di dapat 5,05 mg/L. kelarutan oksigen yang tinggi di perairan memberikan dampak yang positif terhadap udang dan juga biota perairan yang lain.

Natural feed such as phytoplankton, contains high levels of protein, fat, and carbohydrates to enhance the growth performance and immunity in shrimp. Moreover, the presence of phytoplankton in the water column can make the waters shady so that it stimulates the shrimp to actively look for food during the day. Silicate is a macro element that used to promote the cell growth and cell wall formation of plankton. Ceraclean fertilizer product is an artificial hydrated calcium silicate with many small pores so that it is easily soluble in water to facilitate nutrient absorption by plankton cells. This study aims to determine the abundance of plankton in vaname shrimp culture ponds with the addition of ceraclean fertilizer and its correlation to the growth of vaname shrimp. This study uses a household-scale circular pond equipped with microbubble aerator technology with a power of 0.5 HP. The stocking density used was 700 fish/m3 and the maintenance period at DOC was 75. The average weight of shrimp growth at harvest was 9.8 grams with a total biomass of 273 Kg with an FCR of 1.1. A total of 262 ind/ml plankton were identified in household-scale aquaculture ponds with a percentage of Chlorophyta 57.20%, Cyanophyta 37%, Crysophyta 5%, Dinoflagellates 0.8% and Protozoa 0%. This study explains the low intake of feed used during the rearing period and the low FCR value because the shrimp utilizes natural feed. This also causes the growth of vaname shrimp in this study to continue to increase every week with an SR value of 90.1%.

Aquaculture expansion in Pasuruan's coastal areas raises concerns about water and sediment pollution, but the spatial variability and magnitude of these impacts remain insufficiently quantified. This study aimed to assess the water and sediment quality at pond outlets across different aquaculture systems. Samples were collected from seven intensive (high-input shrimp farming), traditional (low-input, extensive ponds), and silvofishery (integrated aquaculture with mangroves) aquaculture farms from July to September 2024, coinciding with peak farming activity. Water and sediment samples were collected from seven farms and analyzed for chemical parameters, organic matter content, and redox potential. Results of the current research record extensive spatial and temporal heterogeneity that is driven by aquaculture management and external events like the WSSV epizootic in August 2024. Ammonia concentrations increased dramatically at stations within intensive vannamei shrimp farms (5.5 mg/L), while downstream stations exhibited natural dilution and mitigation by mangroves. Sediment quality analysis demonstrated a reducing condition with redox potential values from as low as -100 mV and SOM concentrations as high as 23%. Correlation analysis highlighted intensive farming systems as the main drivers of water and sediment degradation, with mangrove belts demonstrating resistance through nutrient adsorption and filtration with COD, TSS, and organic matter as primary pollution contributors. These findings emphasize the urgent need for adopting sustainable practices, such as polyculture systems, reduced feed input strategies, the implementation of constructed wetlands, and enhanced mangrove rehabilitation around aquaculture zones, to minimize environmental impacts and preserve coastal ecosystem health.

Feed management is a crucial component in the cultivation of vannamei shrimp, particularly during the larval stage which requires complex and varied nutritional needs. This study aims to explore innovative feed management strategies by combining natural and artificial feeds in an industrial-scale setting at Hatchery PT Suri Tani Pemuka, Bali. Natural feeds used included Thalassiosira sp. and Artemia salina, along with six types of artificial feeds administered throughout the larval rearing period from Nauplius to Post Larva (PL) 11 stages. Growth parameters, larval health, and water quality were regularly monitored. The results showed that this feed combination provided high nutritional content (45–60% protein, 16–23% fat) and favorable larval survival rates, ranging from 63.62% to 76.15% across the three rearing tanks. There were no significant differences in larval length among tanks (P>0.05), and water quality parameters remained within optimal thresholds. Microscopic observations supported visual assessments, indicating good physiological development in the larvae. This innovative feeding strategy demonstrates strong potential to enhance the sustainability and efficiency of vannamei shrimp larval aquaculture

The vannamei shrimp (Litopenaeus vannamei) is one of the most popular shrimp species, widely cultivated throughout Indonesia. This species has several advantages, including rapid growth, the ability to be cultivated at high densities in intensive systems, and resilience to environmental changes. The presence of plankton and the quality of water in the cultivation medium significantly affect the growth and survival of vannamei shrimp. This study aims to evaluate plankton abundance and the dynamics of water quality in intensive vannamei shrimp farming. The research was conducted at two intensive vannamei shrimp farms in East Java with shrimp aged between 1 and 60 days. Water quality measurements were taken directly from the cultivation ponds (salinity, pH, and dissolved oxygen) and in the laboratory (ammonia, nitrite, phosphate, alkalinity, and total organic content). The average abundance of plankton in the intensive vannamei shrimp farming medium ranged from 190 x 10³ to 960 x 10³ individuals/mL, consisting of four groups: green algae, diatoms, dinoflagellates, and blue-green algae. Green algae were the most abundant group, making up 69.9% to 71.9%, while diatoms were the least abundant at 1.9% to 3.0%. In intensive vannamei shrimp farming, the salinity of the cultivation medium ranged from 16 to 35 ppt, pH from 7.5 to 9.0, dissolved oxygen from 3.2 to 5.7 mg/L, and temperature from 28.0 to 31.3°C. The water chemistry parameters measured were ammonia, nitrite, phosphate, alkalinity, and total organic content, with respective ranges of 0.001–0.030 mg/L, 0.05–1.00 mg/L, 0.25–3.00 mg/L, 104–232 mg/L, and 27–131 mg/L. The dynamics of water quality remained within the optimal range for vannamei shrimp farming, as outlined in Regulation KP Number 75 of 2016 regarding general guidelines for the rearing of tiger shrimp and vannamei shrimp.
