Abstract

Diseases control in tiger shrimp farming activities needs to be done by applying biosecurity and early detection of IMNV. This study aimed to identify the application of biosecurity and IMNV detection in tiger shrimp hatchery activities at the Hatchery Surya Prima Benur. The method of collecting data on the application of biosecurity at the Surya Prima Benur Hatchery is carried out by observing field activities, interviews and participating in activities directly. IMNV detection in tiger prawn fry was carried out by PCR machine. The results of the study indicated that the application of biosecurity at the research site includes infrastructure biosecurity, personnel biosecurity, biota biosecurity, and environmental biosecurity. Detection of IMNV in 6 samples of fry showed negative IMNV results indicated by the absence of a band on the 139 bp molecule according to the positive control. The results of this study can be used as technical guidelines for the implementation of biosecurity and the IMNV inspection process in tiger shrimp hatchery activities.

Abstract

Rumput laut menjadi salah satu komoditas perikanan penting di Indonesia. Pemupukan rumput laut dengan metode perendaman dapat dilakukan untuk meningkatkan pertumbuhan rumput laut. Penelitian ini bertujuan untuk mengevaluasi interval perendaman rumput laut Eucheuma denticulatum menggunakan pupuk PES secara “in vitro”. Rancangan percobaan penelitian menggunakan rancangan acak lengkap (RAL) dengan 6 perlakuan dan 4 ulangan. Perlakuan interval perendaman 0, 6, 12, 18, 24, dan 30 hari sekali. Perendaman dengan 0 jam adalah kontrol. Hasil penelitian menunjukkan bahwa interval perendaman dalam larutan PES memberikan pengaruh nyata (p<0,05) terhadap laju pertambahan panjang dan bobot rumput laut E. denticulatum. Interval perendaman dalam larutan PES pada perlakuan D (24 hari sekali) dapat memberikan pertumbuhan maksimal dengan laju pertambahan bobot mutlak 92,8% dan laju pertambahan panjang mutlak 43,8 %, laju pertumbuhan bobot relatif 1,37% dan laju pertumbuhan panjang relatif 0,76%. Rumput laut yang direndam dengan PES 24 hari sekali memiliki pertumbuhan terbaik dibanding dengan perlakuan lainnya.

Abstract

The aim of this study to observe the reproductive performance and larval development of white shrimp broodstock with adequate feed and water quality control programs. The stages of research were preparation of cultivation media, selection of broodstock, spawning, hatching and rearing of larvae. The broodstock that were spawned came from Hawaii with a weight of 35 g/ind for the male broodstock and 40 g/ind for the female broodstock. The broodstock were fed with marine worms and squid. The larvae were given natural diet in the form of Artemia salina, Thallassiosira sp. and Skeletonema costatum and artificial feed. The results showed that the reproductive performance of the broodstock was observed with the number of eggs 102.400.000 eggs from 667 broods, the average fecundity per broodstock were 143.986 eggs, the number of naupli was 75.520.000 individuals, the hatching rate was 60.9%. Larval development starts from the egg stage which undergoes embryogenesis, hatches into naupli 1-6, then becomes zoea 1-3, mysis 1-3 and post-larvae (PL). Length growth from PL1-PL8 was 3.95-8.05 mm with a survival rate of 43.95%. Water quality during rearing is still in the optimum range for the growth of broodstock and shrimp larvae.
