Abstract

ABSTRACTPENDAHULUANPinctada maxima adalah spesiesakuakultur yang mempunyai nilaiekonomi tinggi (Taylor et al. 1997). Dipasaran internasional, mutiara yangdiproduksi sering kali disebut dengannama “South Sea Pearl”. Indonesiatermasuk salah satu negara penghasilmutiara (South Sea Pearl) yang cukupdiskenal di pasaran dunia, sebagian besarproduksi South Sea Pearl yang dipasarkanberasal dari hasil budidaya (Anna2006). Produksi mutiara berbasisbudidaya merupakan aktivitas usaha yangmenguntungkan. Perkembangan usahabudidaya mutiara saat ini sudah mengarahpada kegiatan industri yang terintegrasi(Fassler 1995).The Effect of Temperature and Salinity to The Physiological Respons on The Larvae ofPinctada maxima (Jameson). Energy budget is one of the most sensitive tools available forindividual assessing environmental changes like temperature and salinity, and also prerequisitefor individual growth and survival. The aim of this study is to obtained information on energybudget on routine metabolism, in different levels of temperature and salinity, and to know thelevels of optimum temperature and salinity. The research was used randomized block design,with three replications. The result showed that optimal temperature and salinity on P. maximalarvae was 28 oC and 32 – 34 ‰ (BE and BF). Energy budget to routine metabolism increasedwas attributed to increased temperature and salinity due to the optimal, than would be decreasedwhen temperature and salinity increased. The highest of energy budged for routine metabolismat treatment BF. Stage I: energy budged between 6.73 – 7.35 C g wet weight-1 hour-1 (28.18 –30.74 J g wet weight-1 hour-1); Stages II: 5.85 – 5.95 C g wet weight-1 hour-1 (24.48 – 24.90 J g wetweight-1 hour-1); Stages III: 4.73 – 4.80 C g wet weight-1 hour-1 (15.07– 19.58 J g wet weight-1hour-1). The highest survival rate of larvae was by treatment BF, but has not higher significant(P e” 0.05) with BE, stage I: survival rate between 87.75 – 87.92 %; Stage II: 81.91 – 82.39 % andstage III: 76.72 – 77.26 %. The best of relative growth length of larvae by treatment BF and notsignificant (P e” 0.05) with BE, at stage I: 29.78 x 17.93 ?m – 30.57 x 18.43 ?m (AP x DV); stageII: 57.62 x 46.73 ?m – 58.13 x 47.33 ?m and stage III: 80.32 x 69.29 ?m – 80.88 x 69.62 ?m. Thequickest time of plantigrade stages have found by treatment BF (day 19.50) and hasn’tsignificant (P > 0.05) with BE (day 20.85).Keywords: Pinctada maxima, larvae, response; physiology, metabolism.Kata kunci: Pinctada maxima, larvae, respon, fisiology, metabolisme.

Abstract

A total of 2466 fish were sampled from Serayu River in Banjarnegara, Central Java. The aims of study are to assessthe relationships among length weight, growth, condition factors and sex ratio of of the brek fish (Barbonymusballeroides) with fragmented habitat. The study started from June 2012 to May 2013 using survey mehods. Thestudy sites consist of six stations which were into three segments based on the reservoir position, i.e lower segment(St.1-St.2), middle segment (St.3-St.4), and upper segment (St.5-St.6). The results show length weight relationshipwere W= W= 7.10 -7*L3.084 (r2= 0.97) for all specimens, W = 8.10-6 *L3.061 (r2= 0.96) for males, and W= 7.10-7*L3.089(r2= 0.98) for females; growth pattern were allometric over all condition factor were almost the both males andfemales, i.e. 1.0234 and 1.0275 respectively. Based on the segment, males were the highest in March at the middlesegment i.e 1.2105 (n= 49) and the lowest at was the upper segment i.e. 0.8952 (n = 29). In females, the highestwas also in March at the upper i.e. 1.1895 (n = 19) and the lowest in April at the lower segment i.e. 0.9478 (n=35); sex ratio consists of 1073 males and 1393 females or 1: 1.29.Key words: growth, length-weight relationship, condition factor, and sex ratio

Abstract

ABSTRACTBrek is a consumption fish belong to barbs group that widely distributed, one of them is in Serayu river. The aims of this study was to reveal the characteristics of meristic, morphometric, and habitat of the species. The study was conducted on the Serayu river especially in Banjarnegara, Central Java Province. Sampling was conducted on May 2012 to June 2013. The area of study was divided into three zones and the zones was categorized based on Reservoirs at Mrica area these are upper zone, reservoir zone, and below the reservoir zone. Fishing gear used are cast net, elektorfishing, and gill nets. Samples of fish were caught preserved in 4-10% formalin solution and then observed in the laboratory. Morphometric characters observed were 24 characters. The results were standardized to standard length, then analyzed with discriminant methods. The structure of the scales and number of ridges on the back of the last dorsal fin spines also observed. The results meristic characters are 4.8 dorsal fin, 3.5 anal fin, 1.14-16 pectoral fin, and predorsal 10-13 scales, also there were no spots on the caudal peduncle. The results of discriminant analysis showed known five characters distinguishing three species near 100%. The habitats have rocky bottom, rapid current, and divide into two groups.Keywords: barb fish, meristic, morphometric, Serayu river
