“…The large composition of dinoflagellates around FNC is thought to be caused by adequate environmental conditions. This is in accordance with previous research [31], that Dinoflagellates can multiply if environmental factors such as light, temperature, salinity and nutrients are adequate. [32] and have an efficient body shape for swimming and are equipped with sensory antennae to determine the position of prey and predators [33].…”

The leftover food and feces from fish aquaculture in the floating net cages (FNC) may contribute to the nutrient enrichment at surrounding FNC water. The phytoplankton community structure is the one of important indicator for water quality evaluation. This research aims to determine the plankton community structure and water quality around FNC, Sendang Biru, Malang. Plankton samples and physico-chemical parameters were taken at 3 locations at surrounding FNC area. The results show that phytoplankton from the Bacillariophyceae class and zooplankton from the Hexanauplia class (copepods) dominate in the community structure. Phytoplankton abundance ranges from 795-11405 ind/L, diversity index (H') ranges from 1.47-2.43, evenness index (E) ranges from 0.76-0.95, and dominance index (D) ranges from 0.1-0.3. Meanwhile, zooplankton abundance ranges from 15-634 ind/L, H' value in range of 2.05-2.58, E value in the range of 0.72-0.84, D value in the range of 0.11 -0.17. Nitrate and phosphate have values that exceed the specified quality standards.

“…Budidaya kepiting bakau masih mengalami kendala antara lain: kurangnya ketersediaan benih dan tenaga kerja (Mardiana et al, 2019); pembudidaya kurang memperhatikan daya dukung lahan (Agus, 2008). Permadi (2018) mencatat rangkaian riset pembenihan kepiting yg sudah dimulai sejak 1984, dan pada periode penelitian 1992/1993 telah berhasil hingga fase crab I, kemudian tahun 2002 telah berhasil pada fase crab IV (5,45%) selama 26 hari, namun tingkat survival rate benih yang dihasilkan masih rendah. Peningkatan kualitas induk dan penanggulangan penyakit saat pembenihan adalah dua aspek yang perlu diteliti lebih lanjut untuk meningkatkan survival rate.…”

Nilai ekspor kepiting Indonesia turun drastis mulai tahun 2015, sedikit mengalami peningkatan di tahun 2019 namun masih jauh dibandingkan nilai ekspor tahun 2013 dan 2014. Komoditas kepiting Indonesia memiliki daya saing yang kuat di pasar ekspor ditunjukan dengan nilai RCA (Revealed Comparative Advantage) diatas satu. Data tahun 2019 menunjukkan Indonesia baru menyumbang 1,66% dari total nilai ekspor kepiting dunia. Volume produksi kepiting dari tahun 2015-2017 masih didominasi oleh tangkapan alam sekitar 75-85% sedangkan produksi dari budidaya hanya 15-25%. Dari produksi kepiting budidaya 15-25% tersebut benihnya masih bergantung dari alam. Produksi kepiting Indonesia masih bergantung pada hasil tangkapan alam, sementara pemanfaatan sumber daya kepiting terbatas. Tujuan kajian ini adalah untuk memberikan gambaran kondisi saat ini budidaya kepiting bakau dan merumuskan strategi pengembangan budidaya kepiting yang belum berkembang secara optimal. Metode yang digunakan dalam penelitian ini adalah melalui study literatur, wawancara dan Focus Group Disscussion (FGD) yang dianalisis secara deskriptif. Permasalahan budidaya kepiting saat ini adalah benih sulit didapatkan pada bulan-bulan tertentu sehingga kegiatan budidaya terganggu. Mengingat pasar yang masih terbuka luas, namun hasil tangkapan mulai berkurang ditandai sulitnya memperoleh benih kepiting dari alam secara kontinyu, maka kegiatan budidaya dari pembenihan harus segera diwujudkan dan ditingkatkan produksinya. Kebutuhan benih untuk kegiatan budidaya sangat besar sehingga diperlukan banyak hatchery.The export value of Indonesian crabs fell drastically starting in 2015, with a slight increase in 2019 but still far from the export values of 2013 and 2014. Indonesian crab commodities have strong competitiveness in the export market as indicated by the RCA (Revealed Comparative Advantage) value above one. Data for 2019 showed Indonesia only contributed 1.66% of the total world crab export value. The volume of crab production from 2015-2017 is still dominated by natural catch, around 75-85%, while production from aquaculture is 15-25%. Of the production of cultivated crabs, 15-25% still depend on natural seeds. Indonesia's crab production still relies on natural catches, while the utilization of crab resources is limited. This study aims to provide an overview of the current condition of mud crab culture and formulate a strategy for developing crab culture that has not developed optimally. The method used in this research is through literature study, interviews and Focus Group Discussion (FGD), which were analyzed descriptively. The problem with crab cultivation today is that seeds are challenging to obtain in certain months, so cultivation activities are disrupted. The market is still wide open, but the catch is starting to decrease, marked by the difficulty of continuously obtaining crab seeds from nature. The cultivation activities from hatcheries must be realized, and production must increase. Seeds for cultivation activities are huge, so many hatcheries are needed.

“…As stated by [24] estuary areas are very productive, and serve as habitats for various types of coastal and marine biota [25] so they have high biodiversity [22,25,26,27,28]. [29] claimed that the estuary ecosystem is used by biota (particularly fish) as a spawning area, nursery, food storage area, and migration route; in an estuary environment fish are generally euryhaline [20].…”

The research was conducted from May to July 2022 in six zones to determine the diversity, niche width, distribution, and community structure of demersal fish. Fish were surveyed using a drift gillnet at a maximum depth of 15 m, identified, and analyzed using clusters and nMDS to determine their grouping. SIMPER analysis was used to discover individual variations between zones and depth strata, while ANOVA was used to determine the significance of individual fish observed. The results of the study found 8 species, 8 genera, and 8 families with Eubleekeria splendens as well as Chelonodon patoca having the highest niche widths (04.42 dan 04.33), then E. splendens, Terapon jarbua, Scatophagus argus, Plotosus canius, C. Patoca, and Johnius carouna were relatively abundant (frequency > 80%). Aside from that, J. carouna is the fish with the most individuals discovered (82 ind and 32.54%). Cluster analysis and nMDS are divided into two groups, with J. carouna being the differentiator between fish groupings based on zonation and C. chanos, C. patoca, and J. carouna being the differentiator between fish groupings based on depth strata. Furthermore, the ANOVA test reveals that individual demersal fish between zones have a significance of < 0.05, whereas individual demersal fish between depth strata have a significance of > 0.05.
