    (2013-06-25) Khairi, Febria; Yusuf Syofyan; Nofrizal
    This research was conducted on 26 June – 5 July 2011 at Village Teluk, Kuala Kampar sub district, Pelalawandistrict in Riau Province. This research aims to examine the construction of drift gillnet fishing gear resulting in a drift gillnet new design. The Method used in this research is a survey method is by directly observing FISHING gear drift gillnet used by fishermen at Teluk Village. Characteristics nets studied and the data are compared according to the discussion of literature study that resulted in the design of fishing gear drift gillnet new. From the comparison there are several differences as follows: webbing; mesh size, the number of mesh size (MD and ML), weight and knot nets. Line rigging; structural line as well as the amount of line ris up and strap ris down below. Buoys; Amount buoys and distance installation. Ballast; Amount weights and distances installation. Peluntang; Amount bouys and distance installation.

    CONDITION OF PHYSIOLOGY FISH TILAPIA (OREOCHROMIS NILOTICUS) ARREST IN THE PROCESS OF USING TOOLS TO CAPTURE ACTIVELY MONITORED ELECTROCARDIOGRAPH (ECG)
    (2013-07-31) Armen, Wahyudi; Nofrizal; Isnaniah
    The research was conducted in March 2013 with the object of Tilapia (Oreochromis niloticus). The research objects are counted by the number of heartbeats different current treatments. The purpose of this study was to determine the heart rate of tilapia (Oreochromis niloticus), a basic knowledge of predicting the rate of metabolism and respiration and heart rate also determine the activity of tilapia at different swimming speeds, in the process of catching up with the use of active fishing gear. The higher the flow rate used in tilapia fishes the heart rate up, and seen in the relative heart rate ranging from (1.1 to 3.78), a portrait that fish require a lot of energy so that the fish is also increasing the body's metabolisme.
