The results showed that the water quality of Padjadjaran Retention basin is suitable for use for aquaculture, it is located near the outlet are more suitable for the placement of fish farming containers with a suitability index of 0.53, compared to in the inlet and in the midlet have a suitability index of 0.18 and 0.17, respectively
Demand Factors Analysis of Catfish Products (A Case Study of Mr. Sumar Catfish Salad Stall in Ujungberung Subdistrict, Bandung City, Indonesia)
No full textThis study aims to analyze the demand and the factors that influence the demand for processed catfish products at Mr. Sumar Catfish Salad Stall in Ujungberung Subdistrict, Bandung City. This research was conducted in September 2021. The method used is a quantitative descriptive method using primary and secondary data. The sampling technique used in this study is accidental sampling, a sampling technique of respondents by chance who met directly with researchers at the research location and were used as data sources. The number of respondents in this study amounted to 100 people. Based on the results of the correlation test, there are results that the correlation coefficient value is 0.97 (close to 1), meaning that there is a relationship between the price of catfish salad, consumer tastes, and business location on demand for catfish salad in Mr. Sumar Catfish Salad Stall in Ujungberung Subdistrict, Bandung City. The results of the T-Test and F-Test also illustrate that all independent variables have a partial and simultaneous effect on the dependent variable. The results of multiple linear regression analysis stated that if there were a decrease in the price of catfish pecel by 1 unit, then the demand for catfish salad would increase by 0.094 units. Because of the minus value of the regression coefficient, the relationship between the price of catfish salad and catfish salad demand is not in the same direction. On the other hand, the relationship between consumer tastes and business location on demand for catfish salad is unidirectional because the regression coefficient value is positive. So if consumer tastes increase by 1 unit, then the demand for catfish pecel will increase by 0.072 units, and also if the business location increases by 1 unit, then the demand for catfish salad will increase by 0.092 units
Effect of Seasonal Variations in Hematology, Biochemical, Immunity Constituents in Mugil cephalus, Chano chanos, and Arius arius on Southeast Coast of Tamil Nadu, India
No full textThe assessment of the effect of seasonal variations on health, hematology, and serum biochemical components of three marine teleost fishes, Mugil cephalus, Chanos chanos, and Arius arius from Kovalam, East Coast Road, Southeast coast of Tamil Nadu, India. The objectives of the study pointed out the effect of seasonal variation on fish health and immunity. During summer and pre-monsoon, a total of 20 samples were collected from each sample, and hematological, biochemical, immunity parameters, and fish health were considered. M. cephalus (L-23.86±1.03; W-171.22±35.42) C. chanos, (L-22.36±1.17; W-163.03±33.32) and A. arius (L-22.62±1.08; W-168.72±35.04) have different length and weight. The WBC, RBC, Hb, and HCT were higher during summer in M. cephalus, C. chanos, and A. arius likewise, these parameters were lower in the pre-monsoon period (P<0.05). The MCV, MCH, MCHC, and ESR of all three species were higher in the pre-monsoon whereas in the summer they decreased. Likewise, leukocytes such as neutrophils, monocytes, lymphocytes, eosinophils, and thrombocytes show minimum levels in the pre-monsoon and attain maximum levels in the summer. Most importantly, in the summer, serum components protein and glucose were higher, while cholesterol and urea were lower, and vice versa. Although IgM and IgG levels (P<0.05) were higher in the summer and declined in the pre-monsoon season. In the lysozyme assay, respiratory burst activity (NBT) (P<0.05) reveals a higher concentration in the pre-monsoon and was lower in the summer. A total of thirteen hematological parameters, six biochemical, and two immunological parameters, and lysozyme and NBT activities showed a significant relationship with fish health throughout the seasonal changes. Based on the findings, M. cephalus shows maximum variations in length, weight, hematology, biochemical, and immunity levels, whereas C. chanos showed minimum variations. Hence the report indicates the seasons mainly impact the physiological status of the fish species
Internal Transcribed Spacer (ITS) Region as Molecular Marker for Parasite Identification in Aquaculture: A Review
No full textMolecular technologies may be quicker and more accurate than the culture, serology, and histology procedures that have historically been employed to identify fish parasites. By using molecular diagnostic methods, parasites can be found in asymptomatic fish, allowing disease outbreaks to be stopped. This review discusses the use of Internal Transcribed Spacer (ITS) markers to detect parasite in aquaculture and their potential applications are discussed. It was found that it is a more reliable marker and species identification in combination with other DNA markers. ITS region are highly polymorphic non - coding region with sufficient taxonomic units. Thus, sequences can be separated at the species level. though ribosomal ITS as a universal barcode marker for parasite identification is still hampered by few limitations, the ITS will remain as the key choice for parasite identification. It remains the most important option for parasite identification. Many studies have been carried out using ITS markers for parasites identification such as cestode, nematodes, Pseudoterranova spp., Anisakis type I, Diplostomum, Gyrodactylids Hysterothylacium sp, Glochidia larvae. This identification of parasites are taken from the species Rainbow trout (Oncorhynchus mykiss), Argentinesea bass, (Acanthistius patachonicus), and other samples from various places

No full textPond aquaculture is an alternative aquaculture activity that has high economic value and can be developed in coastal area. The purpose of this study was to describe the profile of milkfish pond aquaculture in Cemarajaya Village, Cibuaya sub-district, Karawang Regency. The method used is a case study with quantitative analysis and descriptive data analysis. The sampling technique used Purposive sampling with 30 respondents. The result show the first for characteristic of cultivation majority are the male, range of age in 50-54 years with an elementary school of education level and then majority of cultivation have been doing this cultivation 2-6 years. Second for general condition majority cultivation 1-5 Ha area, they buy the fish seed IDR 25-30/fish with transportation cost in IDR 300,000-500,000. The cultivation can be stocking from 300,000 – 500,000 fish/Ha/cycle with cost of fertilizer in IDR 225,000-550,000 and cost probiotic in IDR ≤100,000. The production in cultivation can be 190,000 – 255,000 fish/Ha/cycle which is selling at a price IDR 100-200/fish. The labor can be have 10% from production as a cost of labor. These results indicate that the cultivation of milkfish nursery ponds in the Cemarajaya village can still be imporved in order to get maximum production results, because the current production resuls are still below existing standards
Determination of Trophic Status Based on Chlorophyll-a in Cikidang River Pangandaran, West Java – Indonesia
No full textTrophic status is an indicator of water fertility. In general, there are 3 classifications of trophic status, namely oligotrophic, mesotrophic and eutrophic [1]. According to Linus et al. [2] Chlorophyll-a phytoplankton is often used as an indicator of water quality and water fertility status. This research is to determine the trophic status of the waters based on the concentration of chlorophyll-a in the Cikidang Pangandaran river for the development of fisheries management. The research was conducted from November 2021 - January 2022. The method used was a survey method with a purposive sampling technique. The results showed that the concentration of chlorophyll-a ranged from 3.10-7.77 mg/m3. So it can be said that the trophic status of the Cikidang River is mesotrophic or moderate fertility. Parameters of supporting water quality are temperatures ranging from 26.75-29.570C, Light Transparency ranging from 16.12-135.75 cm, pH ranging from 7.38-7.48, Carbon dioxide ranging from 19.8-47.3 mg/L, BOD ranging from 10.41-16.36 mg/L, DO range from 4.38-5.06 mg/L, Nitrates ranged from 0.25-0.37 mg/L and Phosphate ranged from 0.009-0.02975. The water quality in the Cikidang River generally meets the requirements of class II and III quality standards according to Government Regulation Number 22 of 2021 concerning the Implementation of Environmental Protection and Management, so it is still supportive for the survival of fish resources

No full textFishing activities in Pangadaran District are one of the economic sectors that have been supporting regional development and growth. One of the capture fisheries commodities that contribute to improving the economy, especially the fishing profession in Pangandaran District, is shrimp. Generally, fishermen in Pangandaran District use trammel nets to catch shrimp. This study aims to calculate the Fisherman\u27s Exchange Rate (FER) on small-scale fishermen who use trammel nets in Pangandaran District. Fisherman\u27s Exchange Rate is an indicator of economic welfare for fishermen published by Ministry of Marine Affairs and Fisheries. This research was conducted at the Pangandaran and Cikidang Fish Auction Places, Pangandaran District, Pangandaran Regency, West Java, Indonesia in January-August 2022. This research uses a descriptive type of research method with a quantitative approach. The sampling technique used in this research is census. The data used are primary and secondary data with the number of respondents as many as 45 small scale trammel net fishermen in Pangandaran District with interviews. The data analysis method use Fisherman\u27s Exchange Rate (FER). The results of this research indicate that the average exchange rate for small-scale fishermen is 92. FER shows a number < 100. This indicates that small-scale fishermen who use Trammel net fishing gear in Pangandaran District have a deficit. This means that the economic welfare level of fishermen during the calculation period has decreased compared to the welfare level of fishermen in the basic calculation period
