Abstract

Increasing stocking density in catfish cultivation is part of efforts to increase production to meet catfish needs nationally and internationally. The obstacles faced by household Green mussels (Perna viridis) are a major fishery commodity in Indonesia, producing substantial shell waste. Green mussel shell waste can be used as shrimp feed because of its high calcium content. Nano-chitosan, derived from chitin extracted from green mussel shells, offers enhanced bioavailability and functional properties, making it a promising additive for feed applications. Nano chitosan has the advantage of being biocompatible, biodegradable, and non-toxic. The goal of this study is to create a nano chitosan extract from green mussel shells. Green mussel shells are extracted during the stages of deproteination, demineralization, and deacetylation. The obtained chitosan extract is then combined with Sodium Tripolyphosphate (NaTTP) to yield nano chitosan particles. The nano chitosan particles were then measured and analyzed for the compounds they contained. The extracted chitosan appeared white, with a yield of 71%, which aligns with previous studies on shell-derived chitosan. FTIR analysis confirmed the presence of characteristic chitosan functional groups, including C=O and O-H, at 343 nm. This study successfully synthesized nano-chitosan from green mussel shells that have biocompatibility and high calcium content.

Abstract

This study aims to analyze the biometry of mud crabs caught from mangrove forests to support the provision of kempongan for mud crab cultivators. The research was conducted in Pangkahwetan Village, Ujungpangkah District, Gresik Regency, using a descriptive method. Samples (n= 2,240) collected in the period March-July 2022 from local fishermen. The research variables were biometry, carapace width frequency distribution, condition factor (C), ratio of male and female crabs, and maturity level of mud crabs. Data were analyzed using Microsoft Excel 2013. The sex ratio of crabs caught per month was analyzed by t-test (α=5%). The results of this study obtained a higher male sex ratio (88%) compared to females (12%) in the period March - July, 2022. Mud crab maturity based on the frequency distribution of female crab carapace width was 23.8% (March) , 24.1% (April), 61.5% (June), and 45.8% (July) while male crabs 6.2% (March), 2.9% (April), 6.3% (June ), and 8.2% (July). Male crabs are dominated by thin conditions and female crabs are dominated by fat conditions. The male and female crabs were statistically significantly different. The different conditions between male and female crabs obtained in this study indicate the need for separate management between male and female crabs when used as kempongan in a crab fattening business.

Abstract

Green mussels (Perna viridis) in Banyu Urip Village, Ujung Pangkah Gresik District, have great potential to be developed due to the abundant availability of seeds in nature, easy cultivation methods, namely using floating net cages and step nets, and high market demand. One of the issues with green mussels is the high content of the heavy metal Lead (Pb) in their flesh, which is caused by heavy metal accumulation in the waters. The goal of this study was to isolate, characterize, and test the ability of heavy metal Lead-Pb bacteria to biosorb heavy metal Pb in post-harvest green mussels from sediments and green mussels in the Banyu urip Ujung Pangkah Gresik Sea. The stages of the research included sampling, isolation, macroscopic and microscopic characterization, in vitro testing of Pb heavy metal absorbent. The results showed 6 bacterial isolates, namely two from green mussels coded K1 and K2 and 4 bacterial isolates from marine sediments coded S1, S2, S3 and S4. The six bacterial isolates obtained macroscopic and microscopic characteristics and have been shown in vitro to be able to grow in Nutrient agar enriched 0.8 mg/L Pb(NO3)2.

Abstract

Chlorella sorokiniana is a microalgae with an outstanding nutritional profile and numerous therapeutic substances that can be used as an immunostimulant, including in aquaculture. This research aimed to investigate and characterize peptides isolated from C. sorokiniana protein using TCA digestion and hydrolyzed enzymatically with trypsin. Peptides were then subsequently identified using Tandem LC-MS/MS and Mascot Distiller. Results showed that the percentage of pure protein yield following TCA digestion was 54.66%, and 12 peptides with lengths ranging from 7 to 23 sequences were discovered after trypsin digestion. These peptides originated from various enzymes and chloroplast proteins, including protein synthesis elongation factor TU, photosystem I iron-sulfur center, photosystem II 43 kDa, Ycf4, ATP-dependent zinc metalloprotease FtsH homolog, nitrate reductase, chloroplastic glucose-6-phospate dehydrogenase, and ATP synthase CF1 alpha chain. These findings demonstrated that C. sorokiniana might serve as a source of immunostimulant peptides and proteins, particularly for aquaculture biota.

Abstract

Kabupaten Gresik merupakan salah satu daerah di Jawa Timur yang memiliki potensi budidaya perikanan cukup tinggi. Ikan sapu-sapu (Pterygoplichthys serratus) merupakan salah satu jenis ikan yang menginvasi dalam tambak ikan, termasuk tambak di Kabupaten Gresik. Ikan ini memiliki kemampuan menyesuaikan diri pada lingkungan dengan kadar oksigen rendah sehingga populasinya cenderung berkembang dengan cepat, serta tidak memiliki predator. Oleh karena itu, dilakukan kegiatan pengabdian masyarakat mengenai pemanfaatan ikan sapu-sapu sebagai pakan ikan karnivora dengan sasaran para siswa di SMA Muhammadiyah 1 Gresik. Metode yang digunakan pada kegiatan sosialisasi adalah menggunakan metode ceramah, penyuluhan, focus group discussion, serta demonstrasi. Kegiatan pengabdian pada masyarakat yang dilakukan meliputi perumusan formulasi pakan, sosialisasi mengenai karakteristik ikan sapu-sapu dan pembuatan pakan ikan, serta pemberian pakan uji coba kepada ikan karnivora lele (Clarias sp.). Melalui sosialisasi yang telah dilakukan, para siswa SMAM 1 Kebomas Gresik sebagai sasaran dalam kegiatan pengabdian mendapatkan informasi mengenai pentingnya pemanfaatan ikan sapu-sapu sebagai supplementasi pakan untuk mengurangi populasinya sebagai hama tambak ikan sekaligus memberikan alternatif solusi penyediaan pakan terjangkau bagi ikan karnivora sehingga secara tidak langsung dapat mengurangi biaya operasional pembudidayaan ikan di kolam maupun pertambakan.

Abstract

The rise of the world of ornamental fish in Indonesia has become a business opportunity for various groups. One of them is the ornamental snakehead fish or Channa pulchra. This fish comes from Myanmar and was imported to Indonesia to meet the needs of the ornamental fish market. One of the factors that influence the success of a fish farming business is the FCR and SR values. The lower the FCR value and the higher the SR value, the better the sustainability of the cultivation business. To maintain FCR and SR values, a good quality feed supply is needed. The aim of this research is to determine the effectiveness of supplementing pelleted feed in the form of Spirulina flour and butterfly pea flower flour (Clitoria ternatea), which contain nutrients to support growth and immunity so that they can improve FCR and SR values. The methods used in this research are quantitative and experimental methods. The experimental design used was a completely randomized design (CRD) with 12 containers filled with 1 fish/container. Data were analyzed using the ANOVA test which was carried out with Duncan's advanced test. Observation parameters include FCR value, SR value and water quality. The results obtained showed that there was an effect of providing different additional feeds on the FCR value with the best treatment being treatment A with a value of 3.6 ± 0.61. Treatment B has a value of 5.35 ± 0.21 and treatment K has a value of 4.05 ± 0.53. Meanwhile, the SR value does not show any influence from providing additional feed which is different from the value of 100% for each treatment parameter. Water quality results include a salinity value of 0 ppt, DO 7.16 ± 0.68 mg/l and temperature 29.62 ± 0.82 °C. The water quality value is still considered safe for cultivation unless the temperature is too high which is thought to influence fluctuations in the FCR value.

Abstract

Vannamei shrimp (Litopenaeus vannamei) is a major aquaculture commodity with high economic value, contributing significantly to foreign exchange earnings. Suboptimal management of the aquaculture environment can promote the proliferation of pathogens, particularly Vibrio spp., leading to production losses from vibriosis. This study aimed to biochemically characterize Vibrio spp. isolated from vannamei shrimp aquaculture and to determine the dominant species. Water samples were collected from three brackish water aquaculture tanks in Serang, Indonesia, and cultured on TCBS agar, Hi Chrome Vibrio, and TSA media. Pure isolates were subjected to a series of biochemical tests, including Gram staining, catalase, oxidase, motility, carbohydrate fermentation, aerobic–anaerobic growth, salinity tolerance, MR-VP test, decarboxylase, indole, KCN, urease, and gas from glucose. The isolates were Gram-negative, catalase- and oxidase-positive, motile, curved bacilli, fermentative, and exhibited variations in carbohydrate fermentation patterns (glucose, sucrose, lactose). All isolates grew at 6% salinity and 37°C, with some variations in characteristics between tanks. Based on the biochemical profiles, the isolates were consistent with Vibrio parahaemolyticus, highlighting the need for proper environmental management to mitigate the risk of vibriosis in vannamei shrimp aquaculture systems. These findings underscore the importance of regular water quality monitoring and biosecurity measures to prevent disease outbreaks.
