The study focused on assessing the fecundity and gonadosomatic index (GSI) of the Gongota Loach species, scientifically known as Somileptes gongota, during the period spanning from April 2019 to March 2020. The fecundity of S. gongota exhibited a range of values, spanning from 3375 to 73459.75. Out of a total of 36 specimens, 16 were identified as male while 20 were identified as female. The typical length of female specimens varies between 5.4 cm and 12.5 cm, with a corresponding body weight range of 3.72g to 19.52g. The recorded mean GSI values for the twelve-month period from April to March were as follows: 0.158, 0.231, 0.225, 0.242, 0.176, 0.00, 0.00, 0.13, 0.00, 0.00, 0.00, and 0.134. The lowest mean GSI value of 0.00 was observed during the months of September, October, December, January, and February. Conversely, the highest mean GSI value of 0.242 was recorded in the month of July. According to the monthly mean GSI of female individuals, the observed spawning season for this species spanned from April to July throughout the duration of the study, with the peak season occurring in July. The highest recorded level of fecundity was observed in the month of July, reaching a value of 73459.75. Conversely, the lowest level of fecundity was recorded in August, with a value of 3375. The study revealed a significant correlation between fecundity and body weight, as represented by the equation F=4.51BW-40115, with a coefficient of determination (r2) of 0.835. The observed fecundity values varied between 3375 and 73459.75, while the corresponding body weights ranged from 3.72g to 19.52g. The correlation between fecundity and standard length was determined to be F=0.012 SL3.628 (r2=0.794). The results of the regression analysis revealed a cubic relationship between fecundity and standard length, as well as a linear relationship between fecundity and body weight. A comprehensive understanding of fecundity and gonadosomatic index (GSI) is imperative for effective fish management.

One of the obstacles that exist in this carp hatchery business is the lack of knowledge about the quality of feed that is not in accordance with the nutrients needed by fish. Feed quality that does not match the needs of the fish will lead to a low life-pass rate and fish growth rate. To overcome this, feed mixtures are made using fermented banana stems as a source of probiotics. The use of probiotics becomes an internal solution to produce optimal feed growth and efficiency, reduce production costs, and ultimately reduce environmental burdens due to waste accumulation in waters. The purpose of this study was to determine the right dose and effectiveness of adding probiotics from fermented banana stems mixed directly in carp seed feed on the growth and survival of carp fry. This study was designed using a complete randomised design (CRD). It consisted of 4 treatments and 3 replication for a total of 12 experimental units. The treatments used in this study were treatment A (control), treatment B (1.5 ml/100 g feed), treatment C (3.0 ml/100 g feed), and treatment D (4.5 ml/100 g feed). Based on the results of the study, the highest growth in absolute length and absolute weight and the highest survival occurred in treatment C (3.0 ml/100 g of feed).

This study was conducted in Tanore upazila (sub district) of Rajshahi district, Bangladesh for a period of six months from July 2019 to December 2019. Investigation was carried into the economics of polyculture of Indian major carps with small indigenous fish species (SIS) Shing (H. fossilis), Magur (C. batrachus), and Pabda (O. pabda). The species composition was carps with shing (T1), carps with Magur (T2), carps with Pabda (T3) and only carps (T4). The economic feasibility of four different combinations was analyzed on the basis of the expenditure incurred and total return from sale price of fish in the local market. The net benefits per hectare from 6 months culture period for T1, T2, T3 and T4 were Bangladesh currency (Taka) as BDT. 635730.42, 805548.25, 580948.95 and 291489.07, respectively which largely reflected the gross fish production levels of 7680.42 ± 6.68, 8324.94 ± 16.64, 7581.13 ± 24.94 and 6344.55 ± 10.30 kg ha-1. However, carp polyculture with Magur (T2) provided highest benefit (BDT. 805548.25 ha-1), followed by carps-shing polyculture (BDT. 635730.42/ha-1), carps-Pabda polyculture (BDT. 580948.95 ha-1) and only carps (BDT. 291489.07 ha-1). BCR (Benefit Cost Ratio) was obtained highest in Carp-Magur polyculture, followed by carp-shing and carp-Pabda polyculture systems. So, Carp-Magur polyculture may be better as it has ensured better production of protein enriched SIS Magur and also economic point of view and this system is encouraging for rural people because they would get Magur regularly for consumption and carps as a cash crop.

Social mapping or social mapping is a comprehensive and systematic approach used to gather data and information about the various aspects of a specific area. It involves understanding the social, cultural, and environmental characteristics of the community residing in that area. The process of social mapping was carried out in the Bojongsoang District, encompassing the sub-districts of Tegalluar, Lengkong, Cipagalo, Buahbatu, Bojongsoang, and Bojongsari, situated in the Bandung Regency. This comprehensive study was conducted over a period spanning from December 2022 to June 2023. The research methodology employed in this study involves a qualitative descriptive analysis conducted through a survey. The survey includes direct field observations and interviews with randomly selected respondents who are engaged in tilapia aquaculture. The study involved a total of 45 tilapia farmers and 7 policy stakeholders from each village. The characteristics of respondents who are fish farmers in the Bojongsoang District can be differentiated based on social and economic factors. Approximately 96% of the respondents chose tilapia farming as their main livelihood. Men play a primary role in running the tilapia farming business, while women are also involved in some aspects. The majority of the population adheres to the Islamic religion and belongs to the Sundanese ethnic group. There are kinship ties between the local community and the owners of tilapia farming land. Social stratification exists with the highest positions held by the district head (Camat), members of the regional legislative council (DPRD), and religious scholars (ulama). Meanwhile, community leaders and elders occupy the middle position, while the general population holds the lowest position. Based on the research, the author's recommendations include the need for land use management for tilapia farming practitioners in Bojongsoang and the importance of policy evaluation for stakeholders in the area.

This research aims to analyze the economic potential of the fisheries sector, whether it is a basic or non-basic sector in Cianjur Regency, West Java Province. This research was conducted in Cianjur Regency, West Java Province. The time of the research was carried out in January-April 2023. This research used data on the Gross Regional Domestic Product (GRDP) of Cianjur Regency and West Java Province on the basis of 2010 constant prices according to business field 2016-2021. GRDP is the total value added to goods and services produced by all business units in a certain area. The method for determining the basic and non-basic sectors uses Location Quetion (LQ) analysis by comparing the regency fishery sector with the fishery sector of West Java Province. Location Question analysis is a calculation technique to be able to find out the basic or non-basic sector by comparing the percentage of the contribution of the fisheries sector. Based on the calculation results of the Location Question (LQ) analysis of the fisheries sector in Cianjur Regency, it was found that in 2016-2021 it had an average LQ value of 5.506 (> 1), in which case the Cianjur Regency fisheries sector is the basic sector. This shows that each year has a comparative advantage, meaning that the production of the Cianjur Regency fishery sector can meet the needs of the community in its own region and is able to meet demand from other regions.

This study aims to determine the exposure effect of insecticide with the azadirachtin active ingredient on the immunity of nile tilapia. This research was conducted in March and August for the preliminary test and September-October 2022 for the main test at Ciparanje Inland Aquaculture Hatchery, Padjadjaran University. This study used the experimental method of Complete Randomized Design with five treatments and three repeats. The nile tilapia used is 6-7 cm. The treatment used is exposure to insecticide with different doses, namely A (0 ppm), B (26.25 ppm), C (52.5 ppm), D (78.75 ppm), E (105 ppm). Parameters observed included red blood cell count, white blood cell count, feed response, shock response, and macroscopic symptoms up to day 14. Red blood cell and white blood cell data were analyzed in a quantitative descriptive manner. Data on feed response, shock response, and macroscopic symptoms were carried out in a qualitative descriptive manner. Water quality data were analyzed in a quantitative descriptive manner. The results showed that exposure of insecticide with azadirachtin active ingredient interfered fish health by increasing white blood cell count, lowering red blood cell count, disrupting feed response and shock response. The higher the concentration of insecticide given, the more it affects the immunity of tilapia. Treatment without the addition of insecticides is the best treatment in this study.

Essential oils (EOs) from medicinal plants like lemon (Citrus limon) are considered promising to replace synthetic antibiotics in aquaculture production due to their ability to improve fish health. The aim of the research was to investigate the in vitro antibacterial potentials of varying levels of lemon EO against Streptococcus agalactiae, Escherichia coli, Staphylococcus aureus and Aeromonas hydrophila isolated from Nile Tilapia. This research was conducted at the Microbiology unit., Kenyan Marine and Fisheries Research Institute, Mombasa, Kenya and Environmental Microbiology and Biotechnology Laboratory, Department of Microbiology, University of Ibadan, Ibadan, Nigeria in December 2021. Extraction of EO from lemon peel was performed using steam hydro distillation. The quantitative and qualitative profiling of extracted oil was performed using Gas Chromatography-Mass Spectrometry. The antibacterial potential of lemon EO was tested against some pathogens using the agar well diffusion method while the Minimum Inhibitory Concentrations (MIC) and Minimum Bactericidal Concentration (MBC) were determined by the broth dilution method. The most abundant chemical was D-Limonene (37.56%), 3-Carene (15.88%) and Terpinen-4-ol (93.4%). The lemon EO at 100% and 50% concentration respectively showed the highest antibacterial activity against S. agalactiae (26.00mm and 28.33mm) and E. coli (33.00mm and 30.00 mm); while the least activity was observed against A. hydrophila (8.33mm and 6.67 mm) at P = .05. The MIC and MBC values revealed that 50% lemon EO inhibited bacterial growth for S. agalactiae whereas it was greater than 50% for S. aureus, E. coli and A. hydrophila. Lemon EO has potential antibacterial properties against tested pathogens that affect cultured fish and could be considered a good candidate for further research to develop new antibacterial drugs in aquaculture.
