Abstract

Seaweed (Kappaphycus alvarezii) could be a source of carrageenan needed for industrial sector. The purpose of this study to analyze the characteristics of carrageenan seaweed cultivated with bag and non-bag cultivation systems and different seed weights. The research was conducted in the waters of Bone Bay and the Laboratory of the Indonesian Center for Brackish Water Cultivation and Fisheries Extension in Maros. This study used a factorial completely randomized design (CRD) consisting of factor A (using bags and non-bags), and factor B (seed weight 15, 50, 75, 100, and 125 g). The results showed that the cultivation method factor, seed weight factor, and their interaction had an effect on carrageenan yield, gel strength, ash content and water content (P <0.05). Different cultivation systems with different initial seed weight combinations showed different best results for each parameter. The highest value of yield of carrageenan was observed in the bag culture system with a seed weight of 100 g, namely 29.18 ± 1.10%. The highest value of gel strength was observed in the non-bagged cultivation system with a seed weight of 75 g, namely 1344.69 ± 18.43 g/cm2. The highest value of ash content was found in the non-bagged cultivation system with 125 g of seed weight, namely 30.02 ± 0.13%. The highest value of water content was found in the bag culture system at a seed weight of 15 g, namely 38.63 ± 0.26%. Different cultivation methods and seed weight resulted in other carrageenan characteristics of seaweed for each parameter.

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

Direct discharge of Lapindo hot mud resulted in abundant toxic substances in the Porong River. The impact extended beyond water quality, affecting fish in the river the Porong River which is their habitat. This study aims to characterize the histopathology of Nile tilapia affected by hot mud and assess the environmental conditions of the Porong River. Histopathological analysis revealed edema, congestion, hyperplasia, fusion, and necrosis in gill lamellae. The kidneys exhibited degeneration, inflammation, edema, hemorrhage, and necrosis, while the liver showed hydropic degeneration, vacuolization, congestion, and necrosis. These results indicate that the toxic substances in the hot mud affect the organ conditions of Nile tilapia in the water.

Abstract

Cantang grouper is a leading commodity, especially hatchery centers, namely East Java and Bali which is Indonesia's flagship. The growth of cantang grouper fish is hampered by one of the diseases caused Iridovirus and Viral Nervous Necrosis (VNN). These two diseases attacks the seed stage which causes high mortality, so that early detection is needed for preventive action. This study aims to detect and inventory of Iridovirus and VNN in cantang grouper. This research was carried out at BPBAP Situbondo, Irodovirus was detected using conventional PCR and VNN using rRT-PCR. Cantang grouper samples measuring 2,5-12 cm came from Situbondo and its surroundings, Bali and Lombok with a total of 23 samples. The test results showed that all samples were negative for Iridovirus, while the VNN examination showed 3 positive samples and 20 negative samples. Observation of clinical symptoms showed that the cantang grouper were in good health, swimming actively and did not show symptoms of Iridovirus and VNN infection. The prevalence of VNN infection in cantang grouper 13,04% which was included in the category of frequent infections.

Abstract

Cultivation of the seaweed Gracilaria verrucosa is necessary as a preventive measure against overexploitation. One applicable method is tissue culture, which requires special attention to nutrient needs to support accelerated growth. These nutrients can be provided through fertilization. One commonly used chemical fertilizer in seaweed tissue culture is Provasoli’s Enriched Seawater (PES). This study aims to determine the optimal PES fertilizer dosage for the production of G. verrucosa seedlings through tissue culture using a vegetative propagation method. This study used a completely randomized design with analysis of variance (ANOVA) consisting of four treatments of different PES fertilizer doses with three replicates for each treatment. The results showed that fertilizer dose variation did not significantly affect the absolute growth of explant weight, but tended to increase the number of growth points. Growth points began to increase in the second week for all treatments, and by the fourth week, the number of growth points at a 1.5% dosage showed a significant difference compared to other doses. The application of PES fertilizer in G. verrucosa seedling production through tissue culture with vegetative propagation indicates that different fertilizer doses do not affect explant growth but significantly influence the increase in growth points by the fourth week
