Background: Natural preservatives are compounds produced by natural ingredients that can suppress bacterial growth and development. Natural preservatives are carried out because most of the preservatives circulating are chemicals and unsafe for the body. One of the natural preservatives is by using garlic extract (Allium sativum L).  Objective: This study is aimed to determine the effectiveness of the antibacterial garlic (Allium sativum L) as a natural preservative in fresh African catfish (Clarias gariepinus).  Method: This research used the Pour Plate iroculation method. African catfish (Clarias gariepinus) which is soaked with garlic (Allium sativum L) with a concentration of 7%, 14% and 21% for 30 minutes, then the fish will be kept at room temperature with a storage period of 24 hours and 48 hours and calculated growth in bacterial numbers with the Colony counter.  Result: Based on the research result, it was found that garlic extract (Allium sativum L) can obstruct the effectiveness of antibacterial in African catfish (Clarias gariepinus) at a concentration of 14%.

Fat Diets

Lipids, together with proteins, are traditionally considered as primary fuels during aerobic swimming. The effects of dietary fat and carnitine supplements and exercise on the energy metabolism of juvenile fish were investigated. One hundred African catfish (Clarias gariepinus) were fed four isonitrogenous diets containing a fat level of 100 or 190 g kg-1 diet and one of the two levels of carnitine (15 and 1000 mg kg-1). Fish grew from 61 to 162 g in 10 wk. Thereafter, 6 fish per group swam vigorously for 3 h and the results were compared with unexercised groups. Fish receiving 1,000 mg carnitine accumulated 2- to 3-fold more carnitine than fish receiving 15 mg carnitine. Plasma acyl-carnitine level was affected by an interaction between dietary treatment and exercise (P < 0.05). Adenosine triphosphate and phosphocreatine concentrations were higher in the white muscle (WM) of exercised fish fed the high-carnitine supplements, compared with the low-carnitine fed fish (P < 0.05). Adenilate energy charge indexes were higher and ammonia concentrations were lower in WM of fish fed high-carnitine and high-fat diets. Dietary carnitine supplements may be needed in growing fish when dietary lipid level is high. In that case extra dietary carnitine can maintain the body energy reserves at adequate level when fish is exposed to a short-term, exhaustive exercise, a physiologic stress common both in nature and in intensive aquaculture systems.

Testicular morphology and sperm motility were evaluated in cultured Clarias gariepinus (n = 25) purposively assigned to five groups according to their age. The results showed that the testes were paired, elongated, dorso-ventrally flattened structures, situated in the caudal aspects of the body cavity. The mean length of both right and left testes increased linearly with age, being significantly (p < 0.05) higher at 6 months than at 4 and 5 months of age, and also significantly (p < 0.05) higher at 8 months than at 6 months of age, while the mean weight and organo-somatic index of the catfish testes increased linearly until 6 months of age, after which no significant (p > 0.05) increase in the testicular weight and organo-somatic index was observed. Unidirectional progressive movement of spermatozoa was detected in the milt of C. gariepinus at 6, 7 and 8 months of age, but sperm cells were non-motile at 4 and 5 months of age. Histological sections showed seminiferous lobules, whose germinal epithelia were characterized by many cysts enclosing clones of sperm cells. Each cyst enclosed a clone of sperm cells at an identical stage of spermatogenesis. Spermatids and spermatozoa were present in the lumen of the seminiferous lobule. The obtained results indicate that the morphology of the testes of C. gariepinus is similar to the testes of members of the order Siluriformes, but sexual maturity and production of motile spermatozoa may be achieved at 6 months of age in the African catfish.

Indonesian people have long used garlic as traditional medicine because it contains various chemical compounds that are beneficial to the body. In this study identification of garlicin and kuersetin compounds in garlic as an antibacterial. This study requires 500 grams of garlic each in wet preparations consist of fine garlic and garlic extract, and dry preparation consists of garlic powder. In addition, this research requires 2,1 liters of 96% ethanol. Garlic is dried at 400C with TMI Vacuum Oven and extracted at 250C. Garlic powder is made using Krisbow dry cabinet with a temperature of 1000F and a pressure of 10 Pa. Garlisin content was identified by GCMS Shimadzu TQ8030 and FTIR Perkin Elmer Spectrum Two UATR, while identification of quercetin using Shimadzu HPLC type UFLC. The result shows that the compound garlicin (C6H10S2) was found in the three samples with identical similarity levels. In addition, the three samples showed differences in kuersetin content. The highest kuersetin content was 458.729 ppm garlic extract while the lowest kuersetin content was 81.181 ppm fresh garlic. Both of these compounds have potential as antimicrobial compounds.

The results of reproduction were tested in females of the African catfish (Clarias gariepinus Burchell 1822) after stimulation of ovulation with carp pituitary (4 mg/kg body weight) or with Lecirelin (15 &mu;g/kg) and metoclopramide (10 mg/kg). After administering the synthetic substance eggs were obtained from all females while in the group treated with pituitary homogenate 7 out of 8 hypophysed females spawned. The applied spawning agent did not significantly influence the weight of eggs expressed in grams, but in the case of females treated with carp pituitary homogenate a significantly higher weight of eggs expressed as the percentage of body weight of fish was recorded. The applied stimulators of ovulation did not affect any trait reflecting the quality of eggs. Females used as an experimental material belonged to two categories in respect of body weight: lighter females with average body weight of 2.63 &plusmn; 0.36 kg and heavier females with average body weight of 3.91 &plusmn; 0.48 kg. It was proved that the weight of eggs expressed either in grams or as a percentage of a female&rsquo;s weight was significantly related to the body weight of a female (P &le; 0.01 and P &le; 0.05, respectively), as well as the percentage of fertilised eggs and the percentage of living embryos after 28 hours of incubation (P &le; 0.05 and P &le; 0.05, respectively). The interaction between the stimulator of ovulation and the female body weight was significant only for traits reflecting the weight of obtained eggs (P &le; 0.05 and P &le; 0.01). &nbsp;

In this study, African Catfish (Clarias gariepinus) were cultured in water contaminated with phthalate, benzene and cyclohexane (10 μg/mL), respectively, over a period of 65 days. They were, thereafter, used as protein source to formulate feed for albino rats (Wistar strain) for 28 days. The weights of the body and selected tissues of the rats were monitored and standard enzyme assays were conducted for some enzymes in the serum. Results showed that rats in cyclohexane group gained 58% whereas the control group gained 46% of body weight. Liver weight (absolute and relative) of test rats were found to be significantly lower than that of control (p < .05). Enzyme activity of serum of test rats was found to be significantly higher than that of control (p < .05). Experimental evidence suggests leakage of enzymes from the liver to the serum, thus the elevated serum enzyme activity and that the contaminants may damage the liver.

To investigate quality changes of garlic associated with cultivars and storage conditions, northern type `Seosan' and sub-tropical type `Daeseo' garlics were stored at controlled atmosphere (O2 3%, CO2 5%, -1 ± 1°C) condition, low temperature (-1 ± 1°C), and room temperature (20 ± 5°C). The rate of sprouting, weight loss, enzymatic pyruvic acid content, and degree of greening in crushed garlic were determined during storage. The rate of sprouting was higher in `Daeseo' than in `Seosan' garlic in all storage conditions. Sprouting was effectively suppressed in low temperature and controlled atmosphere storage. Weight loss in `Daeseo' garlic was higher than in `Seosan' garlic. Enzymatic pyruvic acid (EP) contents increased for 3 months storage period, and then decreased gradually as the storage period was prolonged at room or low temperatures. However, EP content decreased dramatically during storage under CA condition in both cultivars. When garlic bulbs were crushed, greening appeared in the garlic stored at low temperature for more than one month. However, greening did not occur in the crushed garlic bulbs stored in CA condition.

Cellular And Humoral Immunity

Growing fish in closed water supply installations with a high planting density leads to accumulation of waste products, turning the habitat into toxic. Growing fish in such an environment leads to stress and increases the stress on their liver, which provides the body with detoxification of metabolites. To reduce stress, adaptogens are used, which increase endurance and survival, increase adaptive plasticity, and strengthen the immunity of fish. We used an adaptogen called Trekrezan. The work aim was to study the morphofunctional changes in liver and its microarchitectonics in African catfish grown using Trekrezan. The analysis of morphofunctional changes in liver allows us to judge the general physiological state of fish body. The liver index of African catfish grown without the use of Trekrezan is significantly higher in both males and females, compared to African catfish grown with Trekrezan, which indicates an intensification of metabolism. Analysis of histological structure of African catfish liver (Clarias gariepinus), grown without the use of the Ttrekrezan, revealed abnormalities of the parenchymal layer of liver with signs of fatty dystrophy, signs of necrotic changes in liver cells, hemorrhages in vascular region, a violation of polarity in the structure of hepatocytes. In species raised in an environment with Trekrezan, these abnormalities are absent, since Trekrezan, due to the activation of cellular and humoral immunity, leads to decrease in intoxication, provides strengthening of immunity, and increases the body's resistance to unfavorable factors of medium.
