Abstract

Vanamei shrimp and milkfish (Chanos Chanos) are now being cultivated in ponds using a polyculture system maintained simultaneously in one container. The development of cultivation technology shows that seaweed can be produced along with shrimp and milkfish in ponds. The addition of seaweed is expected to increase production and improve the environmental conditions of cultivation. This polyculture cultivation system can increase the efficiency of land use can also increase the productivity of ponds. This research was conducted in the pond of Glagah Lamongan village for 42 days. This study used milkfish, shrimp vaname and seaweed Gracilaria verrucosa. The research method uses the Complete Randomized Design (RAL) method with three treatments and three repeats. It gets nine experimental units; the data in the analysis using ANOVA is conducted tukey further tests. Treatment A (density of milkfish and shrimp ten tails/m2, seaweed 250g/m2), treatment B (density of milkfish and shrimp 20 tails/m2, seaweed 500g/m2), treatment C (density of milkfish and shrimp 30 tails/m2, seaweed 1000g/m2). Variables taken are the Absolute Length of milkfish, shrimp vaname and seaweed. The results obtained the total length of milkfish, shrimp vaname and seaweed highest in treatment A (7.67 ± 0.54a). Water quality during maintenance, temperature ranges from 29.2 – 32.8oC; D.O. 1.13.4mg/l; Salinity 1-3 ppt; brightness range 24 – 50 cm and ground redox obtain a range value of 42-(-328)mV. Keywords: Polyculture, Absolute length, Water quality, Soil redox.
