Abstract

Induction of laser puncture in the male catfish broodstock has a positive influence by increasing reproductive activity which is very helpful for the process of gonadal maturation. The contribution of laser puncture induction in accelerating gonadal maturation can be seen with an increasing in the value of Gonado Somatic Index (GSI) and Hepato Somatic Idex (HIS) indicators. The purpose of this study was to examine the effect of laser puncture induction on increasing the value of GSI and HIS male catfish broodstock. This experimental study used 48 broodstocks of one year old male catfish with a body weight of 1000-1200 g maintained in a concrete pond. The treatment consisted of 2 groups i.e. without induction and induction of laser puncture, each treatment was repeated 4 times. Laser puncture induction was performed every 15 days at the point of reproduction for 15 seconds until the 75th day. The parameters observed were GSI and HIS. The results showed that there was a highly significant increase (P <0.002) in the value of GSI and HSI in male male catfish broodtock after induced by laser puncture. Conclusion for this research was laser punctur induction at the point of reproduction in male catfish can accelerate gonadal maturation with indicators of increasing GSI and HIS values.

Abstract

Efektifitas penggunaan kincir air selama masa periode blind feeding budidaya intensif udang vannamei (Litopenaeus vannamei) merupakan salah satu kegiatan penting yang harus diperhatikan demi kelangsungan siklus budidaya yang stabil. Tujuan dari penelitian ini adalah untuk mengetahui tingkat transfer oksigen oleh kincir air serta hubunganya terhadap parameter harian kualitas air tambak. Peneltian ini dilakukan dengan konsep desain kausal ex-post facto selama 30 hari awal masa budidaya intensif udang vannamei (Litopenaeus vannamei) atau selama periode blind feeding budidaya. Hasil penelitian menunjukan bahwa nilai parameter kualitas air di lokasi tambak masih sesuai ambang batas. Sedangkan tingkat transfer oksigen oleh kincir air bersifat fluktuatif selama 30 hari masa pengamatan. Sementara dari hasil uji korelasi menunjukan bahwa hanya variabel suhu dan salinitas air memiliki keeratan hubungan yang kuat terhadap proses transfer oksigen oleh kincir. Sehingga dapat disimpulkan bahwa fluktuasi tingkat transfer oksigen oleh kincir air akan berpengaruh ataupun dipengaruhi oleh kondisi suhu dan salinitas air tambak.

Abstract

Reproduction aspects of banana prawn were important in determining of the fisheries management. These results can indicate the condition of fisheries that are or will be managed. Banana prawn was one of the main commodities in South Sorong fisheries. This study aims to estimate some of the reproductive aspects of Fenneropenaeus merguiensis as part of a management measure to determining the zone to be a no-take zone area in the prospective area of South Sorong MPAs. The data analyzed were from data collecting from January to December 2018 in three sampling sites in South Sorong, among others Inanwatan, Bakoi, and Konda with the results of 5,009 carapace length samples, 4,589 including sex observation and 3,621 including banana prawn GMS observations. Data analysis performed by analyzing the distribution of carapace length frequency, sex ratio, length-weight relationship, length at first maturity (Lm50), and length at first captured (Lc50). The results of this analysis showed that the ratio between male and female gender was not balanced, with male gender to be less with a ratio of 0.4: 1.4 overall in NTZ 2 and 3. Comparison of Lc and Lm in NTZ 2 and NTZ 3 were respectively Lc < Lm and Lc > Lm. More fishing pressure will have implications to reduce the average size of banana prawn caught. Overall, NTZ 3 had relatively more stable conditions compared to NTZ 2.

Abstract

Information abundance and distribution of fish larvae in coastal waters of East Lampung currently very limited. The research aimed to improve the knowledge of the early life of organisms, in order to manag biodiversity and biological resources in the waters. Research station representing the several water sectors: in-shore, near-shore, and off-shore. The research was a representation of eastern monsoon (June) and transition monsoon (September) in 2017. Fish larvae was harvested using bonggo-net tool while its identification to family level using portable Dino-lite. Based on the result the Abundance of fish larvae in eastern monsoon was higher than transition monsoon. This research found 81 families of fish larvae. There were 10 dominant families, that are Gobiidae, Pegasidae, Mullidae, Pomacentridae, Sillaginiidae, Bleniidae, Bythitidae, Carangidae, Pseudochromidae and Bothidae. The distribution of fish larvae in the lower in-shore was higher than near-shore and off-shore, while east and transitional seasons have not much different larval catches.  Temperature, salinity and pH parameters indicated optimal range state for survival and growth of fish larvae, brightness and turbidity in accordance with water quality standards, currents velocity on eastern monsoon is very fast while transition monsoon is fast to very fast. Phytoplankton and zooplankton showed sufficient natural food availability for the life of fish larvae. Result Canonnical Corespondence Analysis (CCA) analysis to connectivity of abundance and larvae distribution showed that the brightness parameter forming a point projection while other water environment condition parameters form a vector projection in both period of monsoon. The abundance and fish larvae distribution in coastal waters of East Lampung in all three sectors of the waters had proportionality to the parameters of environmental conditions, especially the current parameters and the difference of the monsoon period.
