Abstract

The aims of the was study to determine the effect of immersion parent fish guppy pregnant using coconut water with different doses and time of the percentage of male fish seed production. Selected coconut water as a natural ingredient of synthetic hormone replacement 17α-methyltestosterone (MT) is commonly used for aligning the male fish. This research was conducted in June through September 2013 the Laboratory of Fish Hatchery and Breeding Faculty of Fisheries and Marine Science, University of Riau. This study used an experimental method with 12 treatments and 3 replications. This treatment uses doses of 0, 10, 25 and 45 ml of coconut water with immersion time 10, 20 and 30 hours. The results showed that no effect of coconut water toward the percentage of male guppy fish produced with the highest value at a dose of 10 ml were soaked for 20 hours which is 62.5%. Nevertheless, these results are still lower than the MT treatment (92.7%). At doses of 0 and 10 ml no effect on survival rate. However, at doses of 25 and 45 ml guppy fish survival rate decreases.Keywords: Briefing sex, coconut water, guppy fish, Poecilia reticulata

Abstract

This study was conducted on September 2013. This study aimed to determine the correlation between stocking density of seed production (X1), feed pellets (X2), fish farmers experience (X3) and the outpouring of hours of work (X4) on the common carps enlargement pond production. The method used in this study is a survey method with the number of respondents 34 people were taken by simple random sampling of 170 farmers common carps enlargement pond.From the results of multiple linear regression of each production factor to common carps enlargement pond in East Panti Village acquired the production function Y= –0.320+0.022X1+0.905X3+0.027X3–0,008X4. With a regression coefficient (R) was 0.973 and a coefficient of determination (R2) was 0.946. The relationship of production factor common carps enlargement pond had a very strong unindirectional relationship to the production enlargement pond production (sig. = 0.000) so that the factors are key in common carps enlargement ponds business while X4 had the weak trade-offs (sig. = 0.070) or had an excess of working hours.Keywords: Relationship Analysis, Factor Production, Production, Common Carps.

This research was conducted in February 2013 at Tanjung Putus Oxbow Lake.Phytoplankton samples were collected from 3 stations. In each station, there were 2sampling sites, in the surface and in 2.5 Secchi depth. Sampling was done three times,once a week. Objective of this research was to find-out the vertical profiles ofphytoplankton abundance in Tanjung Putus Oxbow Lake. Results of this researchrevealed 47 species of phytoplankton were classified into 5 classes, namely, Chlorophyceae(14 species), Cyanophyceae (6 species), Bacillariophyceae (10 species), Chrysophyceae (1species), and Xanthophyceae (5 species). The phytoplankton abundance at surface rangedfrom 221634-361213 cells/l and in 2.5 Secchi depth ranged from 135814-216923 cells/l. Thevertical profile of phytoplankton abundance was higher in surface than that in 2.5 Secchidepth. The water quality parameters such as water temperature ranged from 30-31oC,transparancy from 89-92.3 cm, depth from 141.7-301.7 m, pH 5.0, dissolved oxygen from3.50-6,17 mg / l, free carbon dioxide from 7.76-15.7 mg / l, nitrate from 0.02-0.1 mg / l, andphosphate ranged from 0.020-0.1 mg / l.
