Abstract

Abalone is one of the species of the Gastropoda class. There are 7 types of abalone that are spread throughout Indonesian waters, including Haliotis asinina, H. varia, H. squamata, H. ovina, H. glabra, H. planate and H. crebrisculpta. Abalone Haliotis squamata is one of the abalone species that is cultivated at Balai Perikanan Budidaya Laut (BPBL) Lombok. The abalone breeding technique at BPBL Lombok is carried out massively with a ratio of male and female abalone breeders of 1:3. The success rate of abalone breeding is determined by the level of gonad maturity, water quality, irradiation period as well as the length and weight of the abalone body. Abalone breeding begins with container preparation by adding 300 chlorinated limes (kaporit). Abalone breeders are maintained by placing them in a 300 x 80 x 80 cm fiber tank containing four baskets, three baskets containing female abalones and one basket containing male abalones. The feed given to abalone breeders is Gracilaria sp. and Ulva sp., while the feed for larvae is Nitzchia sp. feed. Abalone breeding begins with breeder selection. Breeders used are those that have mature gonads or gonads that have entered TKG 3 which are marked by gonad size larger than the shell. Abalone breeders must be over 4 cm in size and free from disease and. Abalone breeding is marked by the presence of a fishy smell and cloudy water in the container. The number of eggs produced from mass breeding is 1,041,600 grains.

Abstract

Intensive cultivation of vannamei shrimp (Litopenaeus vannamei) requires good water quality management to support the growth, health, and survival of the shrimp. This research was conducted at PT. Panen Berkat Sejahtera Bersama (PBSB), East Lombok, for 25 days (April 9–May 3, 2025) with the aim of determining the control techniques for ammonia (NH₃) and nitrite (NO₂) in the cultivation media. The method used was descriptive with primary data collection through observation, active participation, interviews, and field documentation, as well as secondary data from company archives and related literature. The water quality management techniques applied included siphoning the pond bottom, waste disposal through a central drain system, and the use of Aquastar Pond probiotics. The water quality parameters observed included ammonia, nitrite, dissolved oxygen (DO), salinity, and pH. The results showed that ammonia levels were stable at 0.0000 mg/L and nitrite was in the range of 0.007–0.059 mg/L, remaining within safe limits for whiteleg shrimp. DO, salinity, and pH parameters were also within optimal ranges, supporting metabolism, osmoregulatory balance, and nitrifying microbial activity. The application of siphoning techniques, waste disposal, and probiotics has proven effective in maintaining stable water quality and creating optimal cultivation conditions for the growth and health of vannamei shrimp.
