Selamat Malam sahabat Steemian!
Pada kesempatan ini saya akan membagi ilmu tentang lobster laut di kolam semen
Pembesaran lobster laut dapat dilakukan di kolam semen berukuran 1,5 m x 2 m berkedalaman 1 m atau akuarium berukuran 90 cm x 60 cm x 40 cm. Di kolam semen dengan tinggi air 20 cm, dapat dipelihara 100 ekor dan 15 ekor di akuarium, Pakan selama budidaya adalah ikan rucah. Untuk populasi 700 lobster perlu 3 kg/hari ikan rucah.
Supaya anak lobster nyaman, pada dasar kolam dan akuarium perlu ditaruh karang mirip habitat aslinya. Untuk mencegah kanibalisme saat anggota keluarga Palunuridae itu berganti kulit, di kolam dan akuarium dapat diberi tanaman air seperti rumput merah (red grass). Anak lobster juga perlu tempat berlindung. Di alam pada awal perkembangan hidup, udang karang itu bersifat bentik dan hidup merayap.
Anak lobster secara naluri akan mendekati benda tertentu untuk berlindung dari predator. Meski demikian sifat itu bakal hilang sejalan pertumbuhan tubuh. Artinya, peluang kanibalisme ketika dewasa sangat kecil. Berbeda dengan lobster air tawar yang hingga berukuran besar tetap mempunyai sifat kanibalisme tinggi.
Sebab pemeliharaan di bak, sistem filterisasi menjadi penting. Setiap kolam perlu memakai 3 filter untuk menyaring kotoran dari kolam dan akuarium. Pada filter pertama ditaruh pasir. Filter kedua ditaruh karang kecil, dan filter terakhir yang menjadi resevoar tidak diberi material, tetapi menampung limpahan air dari filter ke-2 yang masuk melalui pancuran. Hal itu dilakukan untuk menaikkan kadar oksigen terlarut sebelum dialirkan lagi ke kolam.
Kualitas air pada budidaya lobster harus dijaga. Rata-rata salinitas sekitar 28-32 ppt, pH di atas 7, dan kadar oksigen terlarut 5-8 ppm. Di luar kondisi itu, pertumbuhan udang karang dapat terganggu. Peternak udang karang perlu benar-benar mengecek parameter itu karena seringkali air laut yang dijual berkadar garam sekitar 25 ppt.
Selamat mencoba budidaya lobster laut, semoga bermanfaat bagi kita semua!
