Pertumbuhan Ikan Kerapu (Serranidae) pada Keramba Jaring Apung di Perairan Pesisir Teluk Kodek Desa Malaka Lombok Barat

Abstract

ABSTRACT
Growth of the Groupers (Serranidae) in Floating Net Cages at The Coastal Waters
Kodek Bay Malaka Village West Lombok. Study of rearing of Bararnundi cod
(Cromilileptes altivelis), flowered cod (Ephinephelus fuscogutatus) and estuary
grouper (E. tauvia) at floating net cages was canied out on June to December 2004
at the coastal water Kodek Bay MalakaViiage, West Lombok. There was sigdicant
difference in weight growth rate of groupers during observation (X count = 67.420
and X2a 0.05 = 2 1.026 or X count > X2a 0.05) during observation, but not in length (X2
count = 0.998 and X2a 0.05 = 2 1.026 or X count < X2a 0.05). Observed physicochemical
properties of experimental set up are water temperature between 27.2 - 27.8 OC, salinity
between 3 1.8 - 33.8 %o, transparency between 10.3 - 14.5 m, air temperature between
26.6 - 27.28 OC and pH about 8.3 - 8.4.
