Vannamei shrimp (Litopenaeus vannamei) are one of the mainstays of Indonesia's aquaculture sector, which has great export potential. The development of Millennium Shrimp Farming (MSF) or millennial generation of shrimp farming means that the younger generation is encouraged to actively farm shrimp in a millennial way with the concept of cultivation using small amounts of land, low salinity and maximizing the regulation of water quality. Water quality in vannamei shrimp cultivation is managed by utilizing the application of probiotics and plankton growth. Plankton plays an important role in aquaculture, as natural food and an indicator of the fertility and stability of water bodies. Plankton itself is one of the main components in the food chain system and food web in vannamei shrimp cultivation. The aim of this research was to determine the type of plankton found in the vannamei shrimp ponds of Pangandaran Marine and Fisheries Polytechnic Teaching Factory. The data analysis method used is descriptive quantitative. The test parameters in this research were: plankton abundance, plankton diversity, plankton uniformity and dominance of plankton species found in vannamei shrimp ponds. The results of plankton identification in vannamei shrimp cultivation ponds in Pangandaran Maritime and Fisheries Polytechnic Teaching Factory revealed 7 species of plankton, including: (50-71)% from the Chlorophyta (green algae) group; (16-32)% from the Cyanophyta group (blue-green algae); (2-13)% from the Chrysophyta group (diatoms); 1% from the Phyrrophyta group (dinoflagellates); (2-3)% from the group of protozoa; (1-2)% from the Branchiopoda group and (2-8)% from the Euglenophyta group. The observation results show that the water in vannamei shrimp ponds has moderate biota community stability with plankton uniformity index values under moderate or unstable conditions. Otherwise, there is no individual dominance in the shrimp pond waters.

Seaweed farming is one of the most important aquaculture sectors in Indonesia, contributing significantly to the national economy. Among various species, Eucheuma cottonii is widely cultivated due to its high carrageenan content and industrial value. Optimizing environmental conditions, such as culturing depth, is crucial to improving growth performance and productivity. This study evaluated the effect of different culturing depths on the growth of E. cottonii using a modified floating net cage system in Jepara Bay. The experiment applied three depth treatments—25 cm (A), 45 cm (B), and 65 cm (C)—each with two replications. Seaweed growth was monitored over 49 days and assessed based on absolute weight and specific growth rate (SGR). Results showed that seaweed cultivated at 25 cm had the highest growth performance, with an absolute weight of 102.2 g and the highest SGR, whereas the lowest values were recorded at 65 cm. ANOVA analysis confirmed a significant effect of depth on growth (p < 0.05), supported by Duncan’s test indicating clear differences among treatments. Water quality parameters (temperature, salinity, pH, and dissolved oxygen) remained within optimal ranges, suggesting depth was the primary factor influencing growth. The findings highlight that shallower depths promote greater light penetration and photosynthetic efficiency, thus enhancing E. cottonii growth. A culturing depth of 25 cm is recommended for optimal productivity in similar cultivation systems.
