%X Spiny lobster (Panulirus homarus) has a high selling price at puerulus, pre adult
lobster and adult lobster stages. Pre-adult and adult spiny lobster able to produce
with cultured puerulus by using immersion cages. The performance of puerulus
cultured has not been optimized with different cage sizes and varying stocking
densities. The purpose of the study was to evaluate the performance of puerulus of
spiny lobster cultured at different immersion cage sizes and stocking densities.
The study was conducted with two experimental units of a completely randomized
design using two sizes of tubular immersion cages and three different stocking
densities. The immersion cages used were 77 cm in diameter, 65 cm in height, 8
kg in weight (S immersion cage) and 96 cm in diameter, 89 cm in height, 18 kg in
weight (M immersion cage). The stocking densities of puerulus used were: 200
ind/immersion cage unit; 300 ind/unit and 400 ind/unit. The parameters observed
include: absolute weight growth, daily growth rate, survival rate, feed conversion
ratio and physicochemical parameters of water quality. Analysis of variance
followed by Duncan's test was used to obtain the best immersion cage size and
stocking density. Quality parameters were compared with references to indicate
the feasibility of spiny lobster rearing. The results showed that the performance of
rearing spiny lobster puerulus was optimum in S and M size cages at a stocking
density of 200 ind/unit with the highest survival rate. Even though the absolute
weight growth and daily growth rate were the lowest but significantly different
(P<0.05) from other stocking densities. Water quality parameters during rearing
are included in normal conditions for spiny lobster.

Lobster pasir (Panulirus homarus) memiliki harga jual tinggi pada tahap benih
bening lobster, lobster pra dewasa dan lobster dewasa. Untuk memperoleh produk
lobster pasir pra dewasa dan dewasa, pembesaran benih bening lobster dapat
dilakukan dengan wadah kurungan benam. Performa pembesaran benih bening
lobster pasir belum dioptimasi dengan kurungan benam yang berbeda ukuran
dan padat tebar yang bervariasi. Tujuan penelitian dilakukan untuk mengevaluasi
performa pembesaran benih bening lobster pasir pada ukuran kurungan benam
dan padat tebar yang berbeda. Studi dilakukan dengan dua unit percobaan rancangan
acak lengkap menggunakan dua ukuran kurungan benam berbentuk tabung
dan tiga padat tebar berbeda. Kurungan benam yang digunakan berdiameter
77 cm, tinggi 65 cm, berat 8 kg (kurungan benam S) dan berdiameter 96 cm,
tinggi 89 cm, berat 18 kg (kurungan benam M). Padat tebar benih bening lobster
yang digunakan yaitu: 200 ekor/unit kurungan benam; 300 ekor/unit dan 400
ekor/unit. Parameter yang diamati antara lain: pertumbuhan berat mutlak, laju
pertumbuhan harian, tingkat kelangsungan hidup, rasio konversi pakan dan parameter
fisika-kimia kualitas air. Analisis sidik ragam dilanjutkan uji Duncan digunakan
untuk memperoleh kurungan benam dan padat tebar terbaik. Parameter
kualitas dibandingkan dengan referensi untuk menunjukkan kelayakan pembesaran
benih bening lobster pasir. Hasil penelitian menunjukkan performa pembesaran
benih bening lobster pasir optimum pada kurungan benam S dan M dengan
padat tebar 200 ekor/unit dengan tingkat kelangsungan hidup tertinggi. Meskipun
dengan pertumbuhan berat mutlak dan laju pertumbuhan harian paling rendah
tetapi berbeda nyata (P<0,05) dengan padat tebar lainnya. Parameter
kualitas air selama pembesaran termasuk dalam kondisi normal untuk
pemeliharaan lobster pasir.
