Abstract

A successful capture fisheries business requires a fishing port with excellent facilities. This study, therefore, aims to analyze the current facility utilization rate of Pondokdadap, The Coastal Fishing Port (CFP) and formulate a suitable development strategy. The study was conducted using a descriptive survey from January to April 2021. Twenty-four respondents comprising 11 CFP (Coastal Fishing Port) and FAP (Fish Auction Place) employees and 13 fishers and fish traders were obtained using the inclusion criteria. Primary data was collected through structured interviews based on a questionnaire, while secondary data were obtained through literature reviews on books, articles, and journals related to research. Subsequently, an analysis of facility utilization at CFP Pondokdadap was carried out, while a SWOT analysis was performed on the proposed alternative development strategy. Based on the results, the existing physical condition of the facilities is satisfactory, with varying utilization rates. However, the Government and the CFP Pondokdadap management are encouraged to implement other development strategies, for instance, strengthening fisheries competitiveness by maintaining fish quality, optimizing Sempu Island as a natural breakwater and marine aquaculture fisheries, developing a fishery information system, building supporting facilities at CFP Pondokdadap, as well as improving the quality of human resources, apparatus, and fishing communities at CFP Pondokdadap.

Abstract

Cimanuk River is the second longest river in West Java, flowing from Garut to Indramayu. One of the sub-watersheds of the Cimanuk River is the Cipeles River in Sumedang and Majalengka. Genggehek (Mystacoleucus marginatus) is a type of native fish (indigenous) found in these two rivers. The purpose of the study was to determine growth performance including size distribution, growth pattern and condition factors. The research was conducted by conducting a survey in the dry season in September 2020. The method used was the fisheries biology method. Measurement and data analysis were conducted at the Aquatic Resources Laboratory of Padjadjaran University. The number of fish caught was 231 with a length range of 45 mm - 116 mm and a weight range of 1,1 g – 37,4 g. The growth performance of fish living in Cimanuk River was different from that living in Cipeles River. In Cimanuk River had positive allometric with regression equation W = 4.10-6 L3.2171 and W = 6.10-6 L3.1449. Weight growth was faster than length, condition factor was between 1,27 and 1,33. The growth performance of fish growing in the Cipeles River had a negative allometric growth pattern. The length growth was faster than the weight with the regression equation W = 7.10-4 L2.1182 and W = 7.10-5 L 2.7434, R2 = 0.36 and 0.92, condition factor K = 1.01 and 1.35.

Abstract

This study provides a relevant examination of fish consumption among Indonesian youth; it contributes to their perception of fish quality assurance. A cross-sectional sample of Indonesian youth scholars between 17 and 26 years old (n = 1.163) responded to an online questionnaire validly from February to March 2021. Structural equation modelling was used to estimate the direction and strength of relationships between variables. The results demonstrate that fish availability, health involvement, fish consumption in childhood, sensory beliefs, and price correlated significantly with fish consumption among Indonesian youth, but that relationship was mediated by attitude to consume fish. Social pressure also has a significant correlation to fish consumption among Indonesian youth. Meanwhile, we found that Indonesian youth's perception of fish quality assurance negatively moderates the relationship between fish and fish consumption. This perception of fish quality assurance is likely not to affect the real-world relationship between the desire to consume fish and fish consumption. Understanding the role different variables play in their fish consumption habits may provide helpful insights for the government to develop strategies for increasing the final goal, which is the intake of fish among young consumers.

Abstract

Fishery products are a high source of nutrients, especially fatty acids. The smoking technology with liquid smoke is being developed to preserve fishery products. With this processing, fish are expected to be more durable and have better nutritional content, especially polyunsaturated fatty acids (PUFA), needed in the body. For this reason, research has been carried out to see the impact of fish processing with liquid smoke technology on the fatty acid profile of smoked Indian scad. The method used is the experimental method using coconut shell liquid smoke and samples of fresh and smoked Indian scad. The results showed that the fatty acid profile of fresh and smoked Indian scad contained 27 types of fatty acids consisting of 11 saturated fatty acids and 16 unsaturated fatty acids. The content of polyunsaturated fatty acids (PUFA) in fresh and smoked Indian scad is greater than the content of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). The high ratio of PUFA-ω3/PUFA-ω6 and the low value of Index of Atherogenic (IA) and Index of Thrombogenic (IT) of fresh and smoked Indian scad treated with coconut shell liquid smoke indicate the quality of fish fat is very good for consumption which is beneficial for health.

Abstract

More than 80% of national fishery production is produced by small-scale fishers, who generally have low levels of education and live in small communities, making them vulnerable to global changes. Fishers in small-scale fisheries use simple technology to limit the search for target commodities and new land. Fishing technology and variability of fish commodities are spatial components that reflect the productivity of fish commodities. In this study, cluster analysis was used to identify shifts in the distribution of marine resource use in 2008-2017 in 34 provinces of Indonesia. By understanding the spatial distribution of small-scale fisheries, changes in coastal marine ecosystems can be identified to avoid overexploitation of marine products. The study results show that motorized and outboard motorboats have increased while non-motorized boats have decreased. Skipjack tuna, snapper fish, and crab commodities are a significant production volume. Clustering analysis resulted in three groups with different characteristics. Cluster 3, which consists of Banten, West Java, and North Sumatra, experienced significantly increased fisheries productivity. Therefore, a priority scale program is needed by growing small-scale fisheries' role, such as budget allocations, to improve the economic scale of business actors in these areas.

Abstract

Vannamei is a superior commodity of aquaculture in Indonesia. However, production of vannamei only reached 91.5% of the 450.000 tons revised target. Several factors are the cause of the target not being achieved. One of which is a disease outbreak. The use of probiotics as an application that improves the health status of shrimp is a better choice than the use of antibiotics for treatment. The effectiveness of the application of probiotics to control pathogenic microorganisms is highly influenced by the type of bacteria used. This research was conducted to examine the efficacy of using two different types of probiotics with different bacteria compositions on the productivity of vannamei shrimp. The 2.200 m2 pond plots shielded with low-density polyethene (LDPE) were used. The stocking density was 250 fry.m-2. The vannamei shrimp were fed with an artificial diet containing protein from 30-40%, fat form 5%, fibre form 4%, and water content form 11% during rearing. In preparation and maintenance of water management, probiotics A and B. were applied. The results showed that the use of type B probiotics reached better productivity than type A.

Abstract

The biological aspects of the spotted barb, Barbodes binotatus (Valenciennes, 1842) in Tamblingan Lake were not published yet. This study aims to determine the biological aspects of spotted barb in Tamblingan Lake. Fish samples were captured using gill nets with various mesh sizes at five fixed stations monthly from January to December 2019. A total of 357 individuals of the spotted barb was collected, with the total length of the specimens ranging from 3.9 to 15.6 cm, and total weight varied between 0.93 and 60.30 g. The length-weight relationship for males and females were expressed as W = 0.0375L2.83 and W = 0.0272L3.02, respectively. The growth pattern for males and females was allometric negative and isometric, subsequently. The male-female sex ratio was 1.10:1, and the condition factor for males and females were 0.75-1.42 and 0.40-1.49, respectively. We observed male fish with gonad maturity stage I to IV. In contrast, female fish have gonad maturity stage II to V. The highest gonadosomatic index of male and female fish was found in September, indicating a peak of the spawning time. Fecundity ranged from 57-23897 eggs, with an average of 5901 eggs.

Abstract

The study explored the potentials of C. ferruginea as a nutritional supplement while also testing its possible toxicity to fish. Standard proximate and mineral analysis procedures were used to estimate nutritional composition, while Lorke's and Tainter and Miller's methods were used to determine LD50 of C. ferruginea. Results were presented as means±SD, and analysis of variance was used to test for differences in means. The values obtained for each parameter measured were significantly different (p<0.05) across all the samples. The analyzed ash contents for the crude powder, aqueous, ethanolic extracts were 1.47±0.02, 1.06±0.01, and 0.85±0.01,respectively. A low protein concentration of less than 5% was recorded across the samples. A decreasing trend (75.05±0.25 < 52.09±0.19 < 31.21±0.61) was observed in the carbohydrate values in the crude powder, aqueous and ethanolic extracts, respectively. The mineral composition of C. ferruginea across the samples was significantly different (p<0.05). The crude powder sample had the highest values recorded for all the minerals analyzed, followed by the aqueous and then ethanolic extract except for iron and copper, where ethanolic extract had higher values than aqueous extract. The values obtained for alkaloids, flavonoids, saponin, tannin, phenolic compounds, and oxalates showed a significant increase (p<0.05) in the crude powder sample, aqueous extract, and ethanolic extract, respectively. However, the ethanolic extract had higher values than the aqueous extract for glycosides, terpenoids, and steroids. Of the phytochemical components analyzed, oxalate had the highest value (16.11±0.01) followed by saponin (12.31±0.19), alkaloids (8.12±0.00), and tannin (6.43±0.17). The lowest values were recorded in steroids (0.11±0.00), terpenoids (0.29±0.01), and glycosides (0.34±0.01). LD50 was calculated to be 223.61 mg/kg for aqueous extract of C. ferruginea and 170.29 mg/kg for ethanolic extract (Lorke's method), while 124.82 mg/kg was obtained for aqueous extract and 128.63 mg/kg for ethanolic extract of C. ferruginea (Miller and Tainter method). The behavioural responses observed include weakness, hanging within the water column, and slow response to feeding. Mortality was recorded in some doses. The results indicate that C. ferruginea is a potential source of energy and minerals when incorporated into the fish diet. Its phytochemical constituent is wealthy and could be used in fish health management. However, the plant is toxic and cautiously applied with an LD50 value lower than 2.500 mg/kg.

Abstract

This study examined the length-weight relation and condition factor of Tillapia zilli in River Yobe, Northeast, Nigeria. Three hundred fifty fish species were collected from commercial fishers at selected landing sites within the study area between June and November 2020. The morphometric and meristic characteristics examined varies due to environmental variations such as water temperature, stress, food availability, spawning ground, fishing intensity, and sex. The mean condition factor shows no significant difference (P < 0.05) throughout the sampling period. A linear relationship was established W = 0.4667 L1.1279 and significant at P < 0.01 with b value indicating a negative allometric growth pattern. The correlation coefficient (r2 = 0.5212) indicated that LWR model is reliable. This study provides baselines on length-weight relation and condition factor of Tillapia zilli in River Yobe. Thus further research should be encouraged on the water body for sustainable utilization, decision making, and policy formulation.

Abstract

Despite its importance in global fishery production as the world's second-largest producer, Indonesia is not one of the top ten fish exporting countries. This study uses constant market share analysis to examine Indonesia's fishery export performance. The data was collected from the United Nations International Trade Statistics Database and covered Indonesia's fishery exports from 1999 to 2019. Indonesian fishery products are classified using four-digit Harmonized System codes ranging from 0301 to 0308. Export growth is decomposed into four components: the global market, commodity compositions, market distributions, and competitiveness effects. The results indicate that the significant growth of the global fishery trade was the primary driver of Indonesia's fishery exports during the period. Indonesia is directing a significant portion of its exports to the most dynamic destination markets, such as China and ASEAN countries. The commodity composition and competitiveness effects were negative and significant throughout the period. Indonesia's integration into the global economy through structural adjustment programs, a liberalization strategy, WTO accession, and participation in several trade agreements, but these policies have had little impact on competitiveness. Indonesia's share of the global fish trade has declined from 4.11 percent in 1999 to 2.75 percent in 2019. Over the last 20 years, Indonesia's market share has gone down, which shows its lack of competitiveness.
