Abstract

Dissolved oxygen in aquaculture systems, including aquaponics systems, cannot be filled only by natural diffusion, so an artificial aeration system is needed. Suboptimal aeration levels not only affect metabolic activity, but also affect serum and fish blood performance (hematology). This study aims to evaluate the impact of the aeration system on the health and well-being of fish cultivated in an aquaponics system. The method used is by studying the literature related to the aeration system of fish farming carried out in the aquaponic system which is relevant to the keywords of aquaponic system, aeration system, fish health and hematology from various sources such as: Google Scholar, Elsevier, Springer and Research Gate. Based on the comparison of several studies, it can be concluded that the aquaponic system using an aeration system can improve fish health performance based on hematological parameters.

Abstract

Tilapia (Oreochromis niloticus) is one of the most cultivated freshwater fish. The problem that is often faced in fish farming is diseases caused by parasitic attacks (ectoparasites) which can cause a decrease in fish production levels. To overcome these problems, research is needed on the intensity and prevalence of ectoparasites in tilapia (Oreochromis niloticus) to determine the density of ectoparasite attacks and the percentage of ectoparasites in tilapia. Tilapia (Oreochromis niloticus) samples were taken from the Floating Net Cage (KJA) of Lake Batur, Songan Village, Kedisan and Trunyan. Sampling is carried out by purposive sampling or determining location points. The tilapia (Oreochromis niloticus) samples examined were 36 fish samples with a size of 14.7-21 cm tilapia niwana. The ectoparasite found only in the gills of tilapia, namely Dactylogyrus sp. (506 ind) and Gyrodactylus sp. (13 ind). The highest intensity in the genus Dactylogyrus was 14.06 ind/head in the medium category, while in the genus Gyrodactylus it was 1.86 ind/head in the low category. The highest prevalence value in the genus Dactylogyrus is 100% with the always category while for the genus Gyrodactylus is 19.44% with the frequent category. The data supporting water quality in this study includes temperature, pH, and DO. The temperature of lake water in floating net cages during the study ranged from 23oC-28oC, pH or acidity degree ranged from 8.1-9 and DO range from 4.8-5.6 mg/L. The results of the water quality in this study are classified as optimal for tilapia rearing.

Abstract

The development of the marine and fisheries sector is a mainstay sector to improve the Indonesian economy (Blue Economy), where aquaculture is a fairly productive and growing sub-sector. Not only sea waters, Indonesia also has very good freshwater potential for development based on aquaculture. Silver barb (Barbonymus gonionotus) is a native freshwater fish from Indonesia and is one of the economical consumption fish that is affordable for the community. The data collection techniques used are primary data and secondary data. This technique is carried out by Primary data, namely data obtained in the field from observations during the implementation of research. Primary data can be in the form of direct observation or observation, namely directly observing the activities carried out such as observing fish growth by looking at the increase in length and weight. Secondary data, namely data obtained from various books, journals, statistical data, articles, and others. Maintenance of silver barb broodstock is carried out by preparing the pond first starting from drying, liming, fertilizing, filling with water, then maintaining the broodstock. Maintenance of silver barb broodstock for 28 days resulted in SR (Survival Rate) values for males of 100% and females of 99%, then FCR (feed conversion rate) for males of 1.64 and females of 1.72. Water quality measurements were carried out 5 times a week and the range obtained was temperature 28-32 ⁰C, pH 8–8.6 and DO (Dissolved oxygen) 8–9.7 mg/l.

Abstract

Swamp eel is one of the fishery commodities favored by the community. Swamp eel cultivation activities have not been widely developed due to the lack of feed availability to support cultivation efforts. Instead of using artificial feed, the farmer has used natural feed in the form of earthworms so far. Therefore, in this study, artificial feed and natural feed are combined to stimulate the feed acceptance of the eel. This study determined the proportion between artificial and natural feed on the level of feed consumption of swamp eel. The method used consisted of four treatments: 50% feed + worms (control diet), 75% feed + 25 snails, 50% feed + 50% snails, and 25% feed + snails 75%. The results show that the differences in the proportion of artificial and natural feed did not affect the feed selection, time response, and feed consumption by eel. Therefore, 25% snails and 75% artificial feed are recommended to stimulate the eel's feeding response.

Abstract

Abalone is one of the species of the Gastropoda class. There are 7 types of abalone that are spread throughout Indonesian waters, including Haliotis asinina, H. varia, H. squamata, H. ovina, H. glabra, H. planate and H. crebrisculpta. Abalone Haliotis squamata is one of the abalone species that is cultivated at Balai Perikanan Budidaya Laut (BPBL) Lombok. The abalone breeding technique at BPBL Lombok is carried out massively with a ratio of male and female abalone breeders of 1:3. The success rate of abalone breeding is determined by the level of gonad maturity, water quality, irradiation period as well as the length and weight of the abalone body. Abalone breeding begins with container preparation by adding 300 chlorinated limes (kaporit). Abalone breeders are maintained by placing them in a 300 x 80 x 80 cm fiber tank containing four baskets, three baskets containing female abalones and one basket containing male abalones. The feed given to abalone breeders is Gracilaria sp. and Ulva sp., while the feed for larvae is Nitzchia sp. feed. Abalone breeding begins with breeder selection. Breeders used are those that have mature gonads or gonads that have entered TKG 3 which are marked by gonad size larger than the shell. Abalone breeders must be over 4 cm in size and free from disease and. Abalone breeding is marked by the presence of a fishy smell and cloudy water in the container. The number of eggs produced from mass breeding is 1,041,600 grains.

Abstract

The Kutaraja Ocean Fishing Port (PPS Kutaraja) is one of the largest fish landing sites in Banda Aceh, playing a significant role in shark fisheries, particularly for thresher sharks (Alopias pelagicus). This study aims to describe the thresher shark fishery at PPS Kutaraja, assess the status of its utilization, and provide recommendations for sustainable management. The research was conducted through direct observations, interviews with fishermen and fishery business operators, and secondary data analysis. The results indicate that thresher sharks are primarily caught as bycatch using purse seines and longlines. The shark trade at PPS Kutaraja involves multiple stakeholders, from fishermen and intermediaries (toke bangku) to domestic and international markets. Habitat and ecosystem assessments reveal that seagrass and coral reef ecosystems along the Aceh coast are in moderate condition, while mangrove ecosystems remain relatively well-preserved. The composite evaluation of the Ecosystem Approach to Fisheries Management (EAFM) for habitat and ecosystem aspects scored 66.67, categorized as "good." However, the lack of data on key shark habitats, such as spawning, nursery, and feeding grounds, highlights the need for further research. To ensure sustainability, ecosystem-based management strategies, including establishing conservation areas and stricter monitoring of shark fishing practices, are recommended. Implementing effective policies will support the long-term sustainability of thresher shark fisheries at PPS Kutaraja.

Abstract

Probiotics are microbes that can modify the bacterial structure in fish digestive systems. Probiotics are used as feed additives and can improve the host's health. As a result, it can help to prevent Aeromonas infection. This study aims to determine the effectiveness of bacteria from the swamp (Bacillus sp. and Streptomyces sp.) on feed in preventing Aeromonas hydrophila infection in striped snakeheads. The study used P0 (control), P1 (Bacillus sp.), P2 (Streptomyces sp.), P3 (Bacillus sp. and Streptomyces sp. combination), each bacterium 10 ml kg-1 feed. Total of bacteria, prevalence, fish growth, survival rate, and water quality are among the variables assessed. The fish survival, fish growth, and feed efficiency in Channa treated with a combination of Bacillus and Streptomyces (P3) were significantly highest among other, resulting of best prevalence 2.38%.

Abstract

Tourism significantly contributes to regional economic growth, especially through the development of natural attractions and supporting facilities. Banyuwangi Regency has strong potential in coastal tourism, with Boom Marina Beach emerging as a leading destination undergoing rapid development. However, the COVID-19 pandemic caused fluctuations in tourist visits and heightened competition among destinations. This study explores how tourist attractions and facilities at Boom Marina Beach affect visitor satisfaction, with visiting decisions acting as a mediating factor. A quantitative method using Structural Equation Modeling (SEM) with WarpPLS was applied. Data were collected from 130 visitors through purposive sampling. The results reveal that tourist attractions and facilities significantly affect visiting decisions and tourist satisfaction. Moreover, visiting decisions mediate the relationship between attractions, facilities, and satisfaction. The study is grounded in the Theory of Planned Behavior (TPB), which explains how perceptions of attractions and facilities influence tourist intentions and behaviors. The findings contribute to the theoretical development of tourist behavior models and offer practical implications for destination management. It is recommended that managers improve the quality of attractions and facilities, supported by effective marketing and infrastructure development from the local government. Future research is encouraged to explore additional variables such as destination image and tourist experience to provide deeper insights.

Abstract

Optimizing hatchery techniques for guppy (Poecilia reticulata) production is essential for improving reproductive efficiency and economic viability in small-scale ornamental aquaculture. This study evaluated the effectiveness of a simplified spawning system using sterilized aquaria (40×60×40 cm) with aeration and aquatic vegetation to create a semi-natural environment. Broodstock selection based on gonadal maturity and a male-to-female ratio of 2:4 resulted in high spawning success, with courtship behavior observed by day three. A staged feeding strategy—infusoria and egg yolk (days 1–3), Artemia nauplii (days 4–10), and Tubifex (days 11–21)—supported consistent larval growth from 0.5 cm to 1.6 cm over three weeks. Larval survival reached 91.1%, with 162 of 168 fry surviving by day 21. Stable water quality parameters (24–26°C, 7.6–7.9 mg/L dissolved oxygen, pH 6.7–7.1) were maintained through regular siphoning and water renewal. Economic analysis indicated system feasibility, with a production cost of IDR 1,369,250, revenue of IDR 1,620,000, and net profit of IDR 250,750. The benefit-cost ratio (R/C) was 1.18, the break-even point was achieved at 136.93 fry, and the payback period was 17.7 months. These findings highlight the biological and financial viability of low-cost guppy hatchery systems suitable for rural aquaculture settings. Future research should focus on scaling potential, feed alternatives, and digital monitoring to improve system sustainability and profitability.
