Abstract. Sofarini D, Herawati EY, Mahmudi M, Hertika AMS, Arfiati D, Musa M, Amin M, Supriharyono. 2019. Analysis of stomach content of piscivorous fishes caught in Danau Panggang Peatland, South Kalimantan, Indonesia. Biodiversitas 20: 3788-3793. The purpose of this study was to analyze the stomach content profile of piscivorous fishes caught at the reservaat station and the station without activity as The control station, in the Danau Panggang peatland. Sampling was carried out four times and the index of preponderance stomach content was determined in piscivorous fishes. The results showed there were nine fish species in the reservaat area, including Cryptopterus spp., Pangasius nieuwenhuisii, Chana striata, Anabas testudineus, Pangasius sp., Mastecembelus erythrotaenia, Macrognathus aculeatus, Mystus nigriceps, and Mystus nemurus. Their gut was dominated 89% by Chrysophyta, and 37.5% by Diatom and Navicula. In the area without activity, six species of fish were caught, including Cryptopterus spp, Pangasius nieuwenhuisii, Anabas testudineus, Pangasius sp, Mystus nigriceps, and Mystus nemurus, with 83% of their gut dominated by Diatom. The water temperature was 28.07-33.25º C, brightness (6-115 cm), pH of 4.23-6.97, dissolved oxygen (DO) (1.4-6.5 mg/L) and BOD (7.52-24.92 mg/L) i.e., water quality parameters that tend to be incompatible with the persistence of fishes. These limiting factors of peatland water and extreme conditions led to a limitation at availability of natural food for piscivorous fishes.

Abstract. Musa M, Lusiana ED, Buwono NR, Arsad S, Mahmudi M. 2020. The effectiveness of silvofishery system in water treatment in intensive whiteleg shrimp (Litopenaeus vannamei) ponds, Probolinggo District, East Java Indonesia. Biodiversitas 21: 4695-4701. Whiteleg shrimp (Litopenaeus vannamei) is a popular aquaculture species in Indonesia due to its high market demand. It requires excellent water quality to ensure its growth rate and production. Therefore, intensive culture system is considered. However, the system threatens the sustainability of the adjacent environment and thus proper water treatment is necessary to increase the quality of water used in shrimp farming as well as the wastewater it produces. In this study, we explored the use of a silvofishery system that integrates mangroves into a pond as a potential solution to this issue. This study aimed to assess the effectiveness of the silvofishery system at treating water inputs and effluents of a whiteleg shrimp pond in Probolinggo District, East Java, Indonesia. Eight physicochemical water quality parameters and a phytoplankton community at four sampling sites during neap tide period were examined in this study. The effectiveness of the silvofishery system in increasing water quality was analyzed using analysis of variance (ANOVA), while the diversity of phytoplankton for biomonitoring was measured with the Shannon-Wiener diversity index (H’). The results showed that the mangrove effectively increased the quality of the water supply and wastewater in the intensive whiteleg shrimp pond-especially in terms of nutrient removal-as well as the biodiversity of its phytoplankton community. Other parameters such as TOM and ammonia also decreased, though this was not statistically proven.
