Abstract

Turmeric (Curcuma longa Linn.) is one of the natural sources that can be used to improve the appetizer of fish and this improve the growth of that fish. Research aimed to understand the growth and survival of C.carpio fed with turmeric-enriched pellets was conducted from March to May 2022. There were 4 different dosages of turmeric powder applied, namely T0 (Control), T1 (0.5 g/kg), T2 (1 g/kg), and T3 (1,5 g/kg). The fish was reared in a 25 L container completed with an aerator and filter. The density of fish was 15 fish/container, around 3 g BW and 6 cm TL. The fish was fed ad-satiation, 3 times/day and was reared for 49 days. Sampling was conducted once a week. Results showed that the survival rate of fish in all treatments was good, more than 95 %. The best growth was obtained in T3, as the fish achieved 6.29 g BW and 7.61 cm TL. While the fish of other treatments were lower, they were T0 (4.60 g; 6.72 cm), T1 (4.73 g; 6.85 cm), and T2 (4.99 g; 7.03 cm). The best FCR was also found in T3 (1.37) and the FCR of other treatments were T0 (2.28), T1 (2.10) and T2 (1.97) respectively. Data obtained indicate that the addition of turmeric powder improves the growth as well as the FCR of C.carpio.

Abstract

The purposive of this study, namely to find out how much and what are the sources of income for traditional fishermen's families in Belang District, and the expenses of traditional fishermen's families in Belang District. The Method used in this research is a survey method. The populations in this study are traditional fishermen in Belang District. The sampling method is using a quataed Multi-Stages Purposive Sampling, with the number of sample villages being 15 villages and the sample fishermen taken are fishermen with fishing rods and nets as much as 10% of the total population in each sample village. The data analysis used is descriptive qualitative and quantitative analysis. The standard of living of traditional fishing families is analyzed using the Engel index. Based on the results of the analysis, it is known that the income of traditional fishermen's families in Belang District comes from their main job as fishermen, side jobs outside the field of fisheries. The total incomes of traditional fishermen's families in Belang District on average for one year is Rp.53.394.000. There are two types of expenditures for traditional fishermen's families in Belang District, namely expenditures for food and expenditures for non-food such as clothing, housing, health, education, electricity, transportation and others. The total average expenditure for one year is Rp. 53.394.000, which is divided into expenditures for food needs of Rp. 32.284.500 and expenditures for non-food needs, which are Rp. 21.109.500. The results of the analysis of the Engel index are 60.46%, used to meet food needs only. The proportion for food, which is 39.54%. This is indicates that the standard of living of traditional fishermen in Belang District is still relatively low because more than half of their income is only sufficient to meet food needs.

Abstract

One of the microalgae that are widely used in the industrial world is Spirulina platensis which has high nutritional content of protein, fatty acids, vitamins and antioxidants. In its growth, this microalgae requires media and the addition of macronutrients nitrate and phosphate which greatly affect the growth and productivity of S. platensis biomass. This study aims to determine the effect of nitrate and phosphate concentrations on S. platensis biomass on an indoor scale and to determine the optimal nitrate and phosphate concentrations to achieve maximum biomass. This research was conducted in August 2020 as an experimental method, with culturing S. platensis with the addition of different concentrations of nitrate and phosphate. The design used in this study was a Completely Randomized Design consisting of 5 treatments that are 0 ppm, 10 ppm, 20 ppm, 30 ppm, and 40 ppm, each treatment with 3 repetitions. The source of nitrate and phosphate used is NPK. Water quality parameters during culture with temperatures ranging from 29-30oC, salinity 25-26 ppt, and pH 8. The optimal concentrations of nitrate and phosphate to achieve the maximum biomass is in treatment C (30 ppm) with a total of biomass 0,43 g. Whereas in treatment D (40 ppm) the biomass did not show a significant increase because the dose was too high with a total of biomass only 0,299 g

Abstract

Environmental condition and water quality in general may affects the health status of fish and it represents in the structure of fish organs such as the gill, kidney, and liver. To understand the structure of the gill, kidney, and liver of Pangasius hypophthalmus that live in the Tanjung Kudu Lake (good water quality) and in the Sail River that has been polluted, a study has been conducted from November to December 2020. Twelve fishes (6 fishes/river) were analyzed. The tissue was formalin-fixed and processed through alcohol series, paraffin-embedded, 5m sliced and Hematoxylin-Eosin stained. The histological samples were then studied using a binocular microscope Olympus CX 21. The abnormality level of the tissue was categorized using the Histopathological Alteration Indeks (HAI). Results showed that the fish tissues from both study sites indicate light abnormality signs such as hyperplasia, hypertrophy, and lifted epithelia. The HAI was 2 for fish from the Tanjung Kudu Lake and 3 for the fish from the Sail River. This index indicates that the abnormality may be cured as the water quality improved.

Abstract

The entry of nutrients (nitrate, phosphate and silicate) from land-based anthropogenic activities (industry, agriculture and household waste) through rivers can potentially cause changes in water quality and will affect fertility and aquatic organisms such as phytoplankton. These three nutrients play an important role in the living tissue cells of living organisms and in the photosynthesis process. This study aims to analyze the effect of nitrate, phosphate and silicate content on the plankton abundance in the estuary of the Batang Arau River, Padang, West Sumatra. The method used is a survey method, the determination of the sampling station is done by purposive sampling, data were analysed by Excel and SPSS Software. Based on the results of laboratory analysis, the nitrate content ranged from 0,117 to 0,485 mg/l, phosphate content from 0,239 to 0,704 mg/l, and silicate content from 0,031 to 0,685 mg/l. Planktonic diatom abundance in the estuary of the Batang Arau River ranges from 194 to 750 ind/l. The results of the statistical analysis of the effect of nitrate, phosphate and silicate with an abundance of diatoms are expressed by the equation Y = 743,019 - 481,828Nitrate - 199,552Phosphate - 172,971Silicate. This equation explains that the effect of nitrate, phosphate and silicate content on diatom abundance has an inverse or negative relationship, where nitrate, phosphate and silicate levels increase, the diatom abundance will decrease. The difference of content and the relationship between parameters analyzed in this research are discussed.

Abstract

This research was conducted in April 2021 to analyze organic matter content in the sediment and the abundance of macrozoobenthos. The purpose of this study was to analyze the content of organic matter in sediments and their relationship with the abundance of macrozoobenthos in the waters of the Pakning River, Bengkalis Regency, Riau Province. Sediment and macrozoobenthos samples were taken from the waters of the Pakning River, Bengkalis District, Riau Province. The method used in this research is a survey method. Sampling was determined using purposive sampling at four different stations. The results of this study indicate that the organic matter content of sediment in the waters of the Pakning River has a percentage of 6.73-12.76%. The highest organic matter content is at station 1 of 12.76% and the lowest organic matter content is at station 4 of 6.73%. The highest average abundance of macrozoobenthos was 19.26 ind/m2 at station 1 with the dominant species being Anadara granosa. Connection between organic sediment and abundance of macrozoobenthos has a linear regression equation y = 1.8442 +0.1662x with a coefficient (R2) of 0.1491 which means that the effect of organic matter in the waters of the Pakning River is 14.9% while 85.1% is influenced by other factors. The value of 0.38 indicates that the relationship between organic matter and the abundance of macrozoobenthos is, a moderate relationship
