Tetracycline Hcl

Tetracycline HCl is one of the most commonly used antibiotics in fish farming that aims to control diseases caused by bacteria. The purpose of this study was to determine the presence and the level of tetracycline HCl antibiotic residue in freshwater fishes sold at the Segiri traditional market. The method used in this research was a standard addition ultraviolet spectrophotometry. The results showed that residue level of tetracycline HCl in freshwater fish is 192,067 μg/g – 257,409 μg/g. These result was far exceeded the maximum residue level of tetracycline class antibiotics in meat and dairy based on SNI 01-6366-2000 that limit the residue not higher than 0.1 μg/g

The Impact

The main environmental problems associated with fish farming in Denmark are attributable to the dam, the “dead reach” and nutrient and organic matter discharge. The environmental regulation of fish farming in Denmark started with the Environmental Protection Act of 1974, the Statutory Order of 1985 forbidding wet feed, and the Action Plan on the Aquatic Environment of 1987. In the case of freshwater fish farms, the latter was implemented through the measures stipulated in the 1989 Statutory Order on Fish Farms. The impact of Danish legislative measures to reduce and regulate the environmental effects of freshwater fish farms can be summarized as follows: - the number of fish farms has been reduced from about 800 in 1974 to about 500 at present; - production has tripled since 1974 and has been stable since 1989; - a change from wet to dry feed has reduced the environmental impact of the farms; - the national goals of the Action Plan on the Aquatic Environment of 1987 for reducing fish farm discharges of organic matter, nitrogen and phosphorus have been fulfilled. The main remaining problems are that: - the local impact of fish farms on downstream stream quality is still much too high in about 15% of cases; - the problem of the passage of migrating invertebrates and fish is still unsolved at some farms; - the problems posed by “dead reaches” are still unsolved. It is concluded that sustainable fish farming is possible in Denmark, but with the present technology production will have to be significantly reduced.

Pesticide residues, especially in vegetables and fruits, are a reason for concern with respect to the health of consumers and workers that need to return to areas that have been treated with these agrochemicals. The objectives of this experiment were to (a) study the behavior of deltamethrin residues from different formulations on cucumber fruits; and (b) correlate insecticide contents in the fruits with pickleworm control. Treatments were as follows: (a) control; (b) three 30 mL applications of deltamethrin 25 EC 100 L-1 water (emulsifiable concentrate formulation); (c) three 7.5 mL applications of deltamethrin 100 EC 100 L-1 water (emulsifiable concentrate); and (d) three 3.75 mL applications of deltamethrin 200 CS 100 L-1 water (concentrate suspension). Samples were taken at (-1), zero, 1; 3; 5; 7, and 14 days after the last application. Residues were determined by the gas chromatography technique, using an electron capture detector. In order to evaluate insecticide effectiveness, six infestation surveys were conducted during the same sampling times. Although at low levels, the deltamethrin residues in the fruits were above the maximum residue level (MRL = 0.03 mg kg-1), even one day after the end of the safety interval (2 days), and were higher for the CS formulation. The insecticide was effective to control the pest during the entire evaluation period.

Analysis of diazinon residues in cabbages up to 14 days after the final spray application, showed an initial period of rapid decay followed by a period of slower decay, which approximates to first order kinetics. The Australian maximum residue level of 0.7 mg kg-1 diazinon for the whole cabbage was reached in 2-3 days in summer and 7-8 days in winter. The recommended Australia 14-day withholding period, combined with marketing of hearts alone, conformed to Japanese marketing requirements of 0.1 mg kg-1.

Income Levels

This research aims to analyze the base commodity and income levels of freshwater fish farmers.  The research is conducted by survey method in which location was chosen purposively at Pagelaran and Lugusari Villages, Pagelaran Subdistrict of Pringsewu Regency with consideration that the location are the central of freshwater fish production (minapolitan areas).  The samples are 44 freshwater fish farmers who are members of fish farmers group with farming experience of more than five years.  The data was collected in June to July 2017 and is analyzed by Location Quotient (LQ) analysis to determine base commodity and fish farming analysis to identify income level of freshwater fish farmers.  The result of LQ analysis and fish farming analysis showed that the main base commodity was goldfish with LQ score 1,18 and the highest income level from three business focus (breeding business, enlargement business, also the breeding and enlargement business of goldfish) was an enlargement business of goldfish with an income value of Rp1,556,440.29/1,000 m2/month.Key words: base sector, freshwater fish, goldfish, income, main commodity

In this paper, we introduce three indices of trade which are consequently applied to the case maximum residue level, MRLs of pesticide. The aggregation indices of NTM i.e Li and Beghin index of trade, Heterogeneous index of trade (HIT) and actual heterogeneous index of trade (AHIT) regulations to compute their protectionism relative to international standards. The application of indices to Maximum Residue Limit (MRL) affecting cottonseed and its by-product i.e crude cottonseed oil and refined cottonseed oil, using a science-based standards Codex Alimentarius. In this analysis, the main aim of the article is to show the response of the maximum residue limits (MRLs) adopted by 50 importing countries on exports of the cottonseed commodities for the year 2005 to 2014. In this study, we estimate the augmented gravity model using the ordinary least squares (OLS) and Poisson regression estimators. The results show that maximum residue limits (MRLs) have a trade increasing effect on exports of the cottonseed commodities.
