Abstract

The research was conducted from April until June 2012 at Soil and Water Quali-ty Management Laboratory Fisheries and Marine Science Faculty of Riau University.The aim of the research was to know chemical and physical characteristics of pondbottom soil and profiles of PMK soil as potencial to development fish pond. The meth-od used was experimental and make up profiles in four lokation.Characteristics of fish pond bottom soil showed relatively acidic soil (PodsolidRed Yellow) with pH ranging from 4.9 to 5.7, the medium to hight levels of organicmatter (1.56 to 2.21%) and low of total N and CEC. Some locations are potentialenough to build a fish pond, although still need to achive pond bottom soil primarilyuse agricultural lime and organic matter to increase of on CEC and the productivity offish pond.Key words : pond bottom soil, soil quality, soil profiles, productivity of soil.

Abstract

Peat soils have the poor water quality, due to its low pH, wich ranges between 3-5, reddish-brown color of the water and minerals and contains very few ground-state nutrient-poor ponds. Household waste can not be used. This study was conducted in Faculty of Fisheries and marine Sciences University of Riau. The results shows that the grade of NPK was very significant effectively on zooplankton abudnance and the species of zooplankton were found from all the treatments consisted of for classes, namely Protozoa, Rotatoria, Crustacea and Insecta. Types of zooplankton derived from protozoa class consists of 4 types namely Coccomonas sp, Euglena sp, Ochromonas sp and Pleodarina sp, whereas Rotatoria class consists of two types of Brachionus angularia and Keratella cochlearis, types of classes crustacea consists of 3 types namely Cyclops sp, Moina sp, and Daphnia sp. The first population peak abundance in all treatments at 12th day with the total abundance in each treatmen of P0 (1,947 ind/l), P1 to (4,623 ind/l), P2 to (9,490 ind/l), P3 (6,327 ind/l). While the second peaks abundance population in all treatments occurred 26 day total abudance in each treatments is P0 (3,772 ind/l), P1 (6,813 ind/l), P2 (13,505 ind/l), P3 (11,193 ind/l). Based on total abundance of 14 times sampling the highest abudance was acieved by P2 treatment (9,490 ind/l)) the 12th day, whereas the second-highest of total abudance of P2 occurred at 26th day (13,505 ind/l).

Abstract

Thyroxine hormones (T4) is a technology that is used to stimulate fish growth. This hormone is produced by the thyroid gland and functioning in general metabolism and growth. This study was conducted from May-July 2016 in Hatchery and Breeding Laboratory, Department of Aquaculture, Fisheries and Marine Sciences Faculty, Riau University. This study was aimed to analyze the effectiveness of the thyroxine hormone (T4) at different dosages to the growth of Pawas fish (Osteochillus hasselti CV), and reared with different density. This study used a complete randomized design with two factors (densities and dosages of hormones) and 3 repetitions. The densities that used were 20, 30 and 40 fish / cage. The hormone dosages given in this study were 2, 4, and 6 mg/kg. The results showed that the density 20 fish/cage is the best density in Pawas culture where the best result of the growth parameters obtained. Addition of thyroxine at a dosage of 6 mg / kg of feed provided the best results on the absolute weight growth (5:12 ± 1.70 g), daily growth rate (2.64 ± 12:47%), protein retention (58.76 ± 8:34%) and the levels of muscle glycogen (4:54 ± 0.20). Addition of thyroxine at a dosage of 4 mg/kg feed gave the best results in the absolute long growth (4.72± 0.89 cm), feed conversion ratio (1:44 ± 0.57), fat retention (108.50 ± 12:47%) and the levels of liver glycogen (6:12 ± 2.60).

Abstract

Research of toxicity of industrial palm oil wastewater and sub lethal test to Oreochromis sp. has been conducted on February 1st to March 1st 2009 in Aquaculture Technology Laboratory, Fisheries and Marine Science Faculty University of Riau. Objective of this research is to determine the concentration of a test material or the level of an agent that produces a deleterious effect on Oreochromis sp. during a short-time exposure under controlled condition. In this study, static 96-h acute toxicity tests were carried out using Oreochromis sp. as test organisms. Probit analysis using the computer software EPA and graphical method were used to caculate the 96-h LC50 depending on data suitability. Results of the 96-h LC50 and Biological Savety Level of the industrial palm oil waste water were 126,06 ml/l and 1.26 ml/l respectively.
