Abstract

This research was conducted with the aim to evaluate the performance of blood glucose of brek fish (Puntius orphoides) in response to stocking density stress. Fish weighing an average of 2.21 g with a weight of 27 individuals were given stocking density stress by inserting them into 9 cylindrical containers of 200.96 cm2 width and 3 L volume of peat water with stocking differently for 72 hours. These stocking density treatments are A (2 fishes/0.02 m2), B (3 fishes/0.02 m2) and C (4 fishes/0.02 m2) with three replicates. Blood glucose collected from 1 fish per container at 72 hours. The preliminary test was conducted to determine the oxygen demand of fish through the oxygen consumption level test which can then be calculated oxygen demand from the fish in accordance with the density used. The average value of blood glucose levels of brek fish that were given the stress of stocking density 2 fishes / 0.02 m2, 3 fishes / 0.02 m2 and 4 fishes / 0.02 m2 tends to be low, that is 53 mg / dL, 52.67 mg / dL and 49.33 mg / dL respectively. The response of blood glucose to stocking density stress results in stocking recommendations for culture brek fish ranging from 100-200 fish / m2.

Abstract

Disolved oxygen plays an important role for fish living in its life environment. Information on the ammount of oxygen consumption of a fish in certain volume of water is needed in order to give balancing between the ammount of disolved oxygen and fish in it. The objective of this research is obtaining oxygen consumption level of a juvenile of brek fish (Puntius orphoides) of 5-7 cm body length. Oxygen consumption of fish was measured using a tube that equiped with DO tool (dissolved oxygent, DO), and the tube was filled by fresh water. Measurement of oxygen consumption of juvenil was done by measuring the concentration of dissolved oxygen from fresh water in the respirometer tube, began when fish had entered into the respirometer tube up to two hours observation. The result showed that oxygen consumption rate a juvenile of brek fish (Puntius orphoides) of 5-7 cm length, is ranging between 0.816 and 1.734 mg/hour.
