Abstract

Research aimed to evaluate the reproduction status of snakehead in concrete tankand in natural swamp aquatic. Seven indicators can be made by knowing thesnakehead status indicator reproduction so that breeding manipulation in concretetank can be done. The seven indicators were gonadosomatic indexs, hevatosomaticindexs, body weight, liver weight, gonade weight, egg diameter, fecundity andestradiolthe snakehead in natural swamp aquatic show in Agust month was 3,3 ± 0.09 andhevatosomatic indexs was 1,1 ± 0.05 in Agust month. For gonadosomatic indexs andhevatosomatic indexs in concrete tank in April month was 3.6 ± 0.09 and Januarimonth was 1.0 ± 0.08, respectively. Result of measurement the fecundity and eggdiameter of the snakehead in concrete tank in Pebruary month was 2978.3 ± 7.64and 1.3 ± 0.00 mm respectively, The fecundity and egg diameter of the snakehead innatural swamp aquatic in Januari month was 3080.0 ± 7.91 and Nopember andDecember was 1.5 ± 0.04 mm respectively. The estradiolsnakehead in swamp aquatic show the higest concentration in natural aquatic.Average concentration estradiolpg/ml until December was 169.2 ± 6.22 pg/ml. In concrete tank from 80.5 ± 5.17pg/ml in Juli until 118.3 ± 6.78 pg/ml in April. In general it is concluded that thereproduction status of snakehead was similar between in concrete tank and naturalswamp aquatic. Enviroment ”trigger” was the limited factor in finally gonadematuration.

Abstract

Snakehead and other fish species in waters of the swamp doing spawning at the beginning or in the middle of the rainy season. Gonadal maturation process so as to returntime is limited. Aquaculture development is highly dependent on the availability of seeds that meet the timeliness, quality and quantity. The seeds can be produced continuously if supported by the availability of mature broodstock with good quality eggs. Some research about the role of hormones and or the use of stimulants to the success in support of gonad development and spawning, such as; Siam Jambal fish, Pangasius hypophthalmus (Ernawati 1999), Catfish, Clarias batrachus (Zairin et al. 2001), and catfish, Hemibagrusnemurus (Supriyadi 2005). By because they were with potential to take advantage of folicle Stimulating Hormone (FSH) that serves as the control at the start of the reproductive cycle up to ovulation and spermiasi in fish. The aim of this study was to determine the effect ofthe injection folicle Stimulating Hormone (FSH) in the parent rematurisasi catfish. Results from the start 17007-52327 item, 0,63-1,07 mm egg diameter, IGS range of 4, 13 to8.50%, and ranged from 0.86 2.4% IHS. Based on the results of the study injection folicle Stimulating Hormone (FSH) capable shorten rematurasi processing time.

Abstract

Hatchery technology has been controlled but the technology is not maximized seed maintenance. Continuity seed in cultivation is indispensable. Vitamin C has a very big role in the physiology of fish primarily as an antioxidant and anti-stress and curcuma component containing a nutritious oil asitri. Curcumin stimulate liver cells to improveand facilitate the production and secretion of bile, there by improving digestion and accelerate gastric emptying.This study was conducted over five months starting from the preparation,execution, and reporting. This research was conducted in the village Mentaos, Banjarbaru, South Kalimantan. The parameters studied were weight growth, length growth, survival rate, feed conversion, protein retention and fat retention by using statistical test completely randomized design (CRD) with 4 treatments and 3 replications.A treatment using commercial feed shrimp with the codes FL 0, treatment and use of commercial feed, thoroughly mixed with vitamin C brand Sido Muncul C1000 much as1000 mg / kg feed, treatment C using commercial feed FL 0 thoroughly mixed withginger 150 g / kg of feed, and D treatment using commercial feed FL 0 thoroughly mixedwith vitamin C as much as 1000 mg / kg feed and ginger 150 g / kg of feed.The results showed that the commercial feed was given vitamin C and curcuma provide survival rate value and the best feed conversion in post larval climbing perch. Best survival value 23.49% and feed conversion value of 0.51. The results of research into the use of vitamin C and curcuma can be recommended to farmers fish farmers to increase the value of the survival of post larvae climbing perch.

Abstract

The problem of the breeding of the snakeskin gouramy management was theinsufficient maximum degree of hatching eggs which only reached 80.03 %. One of the ways to overcome the problem was to improve the quality of eggs through the improvement of quality of feed given to the mothers of snakeskin gouramy withsupplements and food additives. This study aimed to evaluate the reproductive response of female snakeskin gouramy against the addition of supplements and feed additive, suchas: fish oil, vitamin E and extracts of ginger. The tested fish was female snakeskin gouramy with a minimum age of 8 months and were at maturity level of TKG I or TKGII. The Food used in this study were 3 kinds of commercial feed with the addition of vegetable oil (FCO), the feed with the addition of fish oil and vitamin E (FOT) and the feed with the addition of fish oil, vitamin E and extracts of ginger (FOTG).The results showed that FOT and FOTG could produce gonadosomatic index (GSI), fecundity, egg diameter, hatching eggs and survival rate better than the FCO feed.This occured presumably because of the effect of the addition of vitamin E that prevent edoxidation of fatty acids, so that fat could be used completely. As a result, the quality and quantity of eggs increased. GSI value on all treatments ranged from 3.07 to 3.57 %,fecundity ranged between 3,875 to 5,355 grains, egg diameter ranged from 0.70 to 0.93mm, hatching ranged from 78.12 to 89.58 % and survival rate ranged between 51 to 83 % in all treatments. Food with the addition of fish oil and vitamin E could produce better diameter of eggs and survival rate, while feed with the addition of fish oil, vitamin E and extracts of ginger could generate value gonadosomatic index (GSI), fecundity and hatching eggs higher.

Abstract

The Reproductive ability of parent fish which just finish spawming are common with stage I of gonadal maturity takes for a long time. Gonad may not mature if it is notgiven treatment. Doses of OODEV between 0,3 – 07 cc/kgs body weight give effect in inducing gonadal maturation.This Research shows that the highest fecundity was an average of 33190 eggs obtained from on Treatment C, and the largest egg diameter was an average of 0,7 mm also obtained in the treatment C. The highest HIS score was in treatment C (0,95%), while the highest IGS value obtained in treatment A (13,183%). The result of the Observations on the gonad histology climbing perch parent fish was the treatment with OODEV hormones caused the development of maturity level. Change in values and levelsof water quality were considered metting the standard for live fish climbing perch fish. The statistical test result on all the above test parameters showed that al was notsignificantly different among all treatment given; thus from the given hypothesis HO wasaccepted and H1 was rejected which means that OODEV injection dose did not significantly affect the maturation procces. The treatmen with OODEV was more than the level without the use of OODEV Hormones (Control). This is because of the role of the FSH in OODEV Hormone influenced the development of biosytesis of estradiol -17 betha and gonad.
