Abstract

Sea urchins were ecologically and economically important biota, but scientific information on sea urchins is still very minimal and there is no ongoing monitoring. The purpose of this study was to determine the density, abundance, community structure, and distribution patterns of sea urchins in the intertidal zone of Karanrang Island, Pangkep Regency. The research in June-July 2022 was carried out at high and low tide using three transects measuring 1 x 1 m consisting of four plots measuring 50 x 50 cm.  Determination of stations based on information from local residents to get observation stations based on tidal conditions. The results showed that three species of sea urchins from two families were found, namely Diadema setosum, Echinothrix calamaris, and Tripneustes gratilla. The species of D. setosum was found to be very abundant (97.3-97.6%) and tended to be more abundant during high tide than during low tide. The index of diversity and uniformity of porcupine species is low (H' = 0.130-0.142 and E = 0.118-0.129). The species dominance index was in the range of 0.946-0.953 indicating high dominance of D. setosum. Spatially, D. setosum had a uniform distribution pattern, whereas E. calamaris and T. gratilla were distributed in clusters. Further spatial and temporal research is needed to comprehensively determinant the conditions of the sea urchin population on Karanrang Island, Pangkep Regency.

Abstract

The practical application of waste recycling as feed supplement is potentially required by small-scale aquaculturist. Furthermore, some of the flour derived from waste sea urchin shells and in adopted in feed, including Deadema setosum were evaluated to estimate the effect on white shrimp Litopenaeus vannamei moulting. This research required the experimentation of four doses with triplicate supplementation (0, 2, 4, and 6 g 100 g-1 of feed) on shrimps four times daily (12% of body weight) for 35 days test period. The juvenile specimens, characterized by an initial weight of 1.61±0.11 g, were stocked at a density of 12 individuals in a 12 L aquarium. In addition, four compartments were created in each aquarium to facilitate progress observations. The proximate analysis results showed a 53.76±0.27% calcium content in the shell flour, which significantly increased (P0.05) after higher dose supplementation, in the sequential order 18.65±0.13%, 20.04±0.08%, 23.18±0.10%, and 25.04±0.11%. Moreover, the frequency and moulting interval with 4 g doses (16.59%±0.36% day-1 and 5.91±0.18 days-1) were significant (P0.05) and considered the best, compared to 0 g (10.48% ± 0.24% day-1 and 9.97±0.37 days-1), 2 g (13.49%±0.96% day-1 and 8.10±0.29 days-1), and 6 g (13.81%±0.24% day-1 and 7.90±0.06 days-1). In addition, the respective trend pattern for both parameters increased and decreased at 4 g and 6 g, correspondingly. The highest moulting intensity was also obtained with the 4 g doses, at a range of 4 to 6 times, while the lowest (0 g) varied from 3 to 4 times. These sea urchin shell flour was determined to have numerous practical applications as a feed supplement with proven ability to stimulate moulting in vannamei shrimp.Keywords:MoultingCalciumShellSea urchinFeed supplementationVannamei shrimp

Abstract

ABSTRAKSistem ko-kultur yang menggabungkan hewan akuatik dengan tanaman padi selama ini lebih banyak dipraktekkan di air tawar. Eksprimen empat sistem budidaya (monokultur, polikultur, IMTA-non padi, dan IMTA-padi) di air payau dengan tiga ulangan telah diteliti untuk mengevaluasi Laju Pertumbuhan Spesifik (LPS) dan Pertumbuhan Karakteristik Morfometrik (PKM) udang windu. Sebanyak 20 ekor udang windu dikombinasikan dengan ikan nila dan kerang darah masing-masing 20 ekor dan 10 ekor teripang pasir. Sementara itu, 4 rumpun padi salin diapungkan pada bak pemeliharaan dengan menggunakan nampan. Selama 4 minggu, LPS udang windu relatif bervariasi diantara sistem monokultur, polikultur, IMTA-non Padi, dan IMTA-Padi, masing-masing 2,6±0,1% per hari, 3,0±0,3% per hari, 2,9±0,1% per hari, dan 3,3% per hari. Pola yang sama diperoleh untuk PKM (panjang total, panjang kepala, panjang badan, dan panjang karapaks). Analisis ragam menunjukkan bahwa sistem budidaya mempengaruhi secara signifikan LPS dan PKM udang windu (p0,05). Uji HSD Tukey mengindikasikan bahwa LPS dan PKM tertinggi pada sistem IMTA-Padi secara signifikan (p0,05) lebih tinggi dibandingkan sistem monokultur, polikultur, dan IMTA-non padi. Namun, pada ketiga sistem budidaya ini tidak mengindikasikan perbedaan yang signifikan (p0,05). Hasil penelitian skala laboratorium ini memberikan informasi penting potensi pengembangan budidaya udang windu berkelanjutan melalui sistem IMTA-padi di air payau.Kata Kunci:  air payau, ko-kultur, pertumbuhan, udang windu,ABSTRACTThe co-culture systems that combine aquatic animals with paddy have been practiced more in fresh water. Four experimental culture systems (monoculture, polyculture, IMTA-non paddy, and IMTA-paddy) in brackish water with three replications were conducted to evaluate the Specific Growth Rate (SGR) and Growth Morphometric Characteristics (GMC) of tiger shrimp. A total of 20 tiger prawns were combined with 20 tilapia and blood clams and 10 individuals of sea cucumbers. Meanwhile, four clumps of saline paddy were floated in rearing tanks using trays. During the four weeks, SGR of tiger prawns varied relatively between monoculture, polyculture, IMTA-non paddy, and IMTA-paddy systems, respectively 2.6±0.1% day-1, 3.0±0.3% day-1, 2.9±0.1% day-1, and 3.3% day-1. The same pattern was obtained for GMC (total length, head length, body length, and carapace length). Analysis of variance showed that the aquaculture system significantly affected to SGR and GMC values (p0.05). Tukey's HSD test indicated that the highest SGR and GMC values were significantly (p0.05) higher in the IMTA-Paddy system than in the monoculture, polyculture, and IMTA-non paddy systems. However, three cultivation systems did not indicate significant differences (p0.05). The results of this laboratory scale research provide important information on the potential for developing sustainable tiger prawns cultivation through the IMTA-paddy system in brackish water.Keywords: brackish water, co-culture, growth, tiger prawns,

Abstract

Increasing the productivity of aquaculture must be supported by feed input; however, in addition to being expensive, this input can produce nutrient waste. Therefore, finding inexpensive alternative forms of feed with environmentally friendly cultivation practices is important to do simultaneously. This study aimed to determine the effect of variations in the form of maggot feed on the Nutrient Reduction Efficiency (NRE) of freshwater clams (Pilsbryoconcha exilis) in an integrated multitrophic aquaculture (IMTA) system. This 28 day experiment used a Completely Randomized Design (CRD) with four types of feed treatments (live maggots, dried maggots, supplemented maggots, and commercial feed (control). A total of 10 individuals of freshwater clams combined with 10 tilapia fish and freshwater lobsters respectively, as well as 4 clumps of rice were floated in a rearing tank with a volume of 50 L of fresh water. The results of analysis of variance showed that variation in feed had a significant effect (P<0.05) on the NRE of ammonia (NH3), nitrate (NO3), phosphate (PO4) by freshwater clams (Pilsbryoconcha exilis). Tukey HSD test results indicated that the highest NRE of ammonia (NH3) in live maggots feed was significantly different (P<0.05) from dried maggot feed and supplemented maggots, but not significantly different (P>0.05) from commercial feed. NRE nitrate (NO3) was significantly different in each treatment. Meanwhile, the highest NRE phosphate (PO4) in live maggots feed was not significantly different (P>0.05) from dried maggots, but was significantly different (P<0.05) from supplemented maggots and commercial feed.

Abstract

There are several threats to the sustainability of the Tilapia fish cultivation business in the Muara Tami District, which is one of the Tilapia fish production centers in Jayapura, Papua Province. The research was carried out with the aim of analyzing the sustainability of fish cultivation development in the Muara Tami District, Jayapura City, carried out from October to December 2023 with interviews with 30 fish cultivators, data processing and analysis methods using Multi-Dimensional Scaling-Rapid Appraisal for Sustainability ( MDS-Raps) which is a modification of Rapid Appraisal for fisheries (Rapfish). The research results show that the sustainability status of fish farming in the Muara Tami District in the ecological, social, economic, technological and institutional dimensions (multidimensional analysis) is 36.63% in the less sustainable category and the results of the analysis show that the sustainability dimension that has the largest index value is the economic dimension. So a simultaneous strategy is needed for all four dimensions to develop and improve indicator attributes in the social, ecological and technological dimensions, especially in the institutional dimension.

Abstract

The plant species mangrove has been knowed to be effective for the bio-desalination process. However, there is currently no scientific evidence supporting the ability of mangrove bio-desalination when implemented through the floating method. This laboratory-scale study aimed to evaluate the bio-desalination of several mangrove species using the floating method. This study consisted of four treatments and three replicates. Treatments included a control group without mangroves (treatment A) and three treatments using mangroves (treatments B, C, and D), Bruguiera sp., Rhizophora sp., and Avicennia sp., which were positioned floating in a tank using a tray. During the eight weeks of rearing, nutrients were provided through 60 mL liquid NPK fertilization. The results showed that there was a decrease in salinity concentration in all mangrove treatments between 22.5-23.9 ppt from the initial salinity of 30 ppt. Different results were observed for the treatment without mangroves, and the salinity concentration tended to increase until the end of the research to 31.6 ppt. The highest Salinity Reduction Efficiency (SRE) was achieved by Avicennia sp.. (25.1%), followed by Rhizophora sp. (22.8%), and the lowest in Bruguiera sp. (20.3%). The results of this study showed that bio-desalination using mangroves had a significant effect on SRE, and each treatment indicated a significant difference (p<0.05). The results of this study provide initial evidence of the potential of the mangrove floating method for bio-desalination of seawater into brackish water.
