Abstract

Kalsium merupakan salah satu makromineral yang berperan penting dalam proses pengerasan kulit udang pasca molting. Pada tambak salinitas rendah, sering mengalami kekurangan kalsium yang dapat berdampak pada kegagalan molting udang bahkan menyebabkan kematian. Penelitian ini bertujuan untuk mengkaji pertumbuhan, tingkat kelangsungan hidup, dan rasio konversi pakan udang vaname (Litopenaeus vannamei) yang dipelihara pada media kultur salinitas rendah dengan penambahan konsentrasi mineral kalsium berbeda. Penelitian ini dilakukan pada media bersalinitas 5 ppt, menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan tersebut berupa penambahan makromineral kalsium yang berbeda, yaitu: A (0 mg/L), B (50 mg/L), C (100 mg/L), dan D (150 mg/L). Hasil penelitian menunjukkan bahwa penambahan kalsium yang berbeda pada media salinitas rendah berpengaruh terhadap pertumbuhan, tingkat kelangsungan hidup, dan rasio konversi pakan udang vaname. Pertumbuhan terbaik terjadi pada perlakuan penambahan kalsium 0 mg/L (kontrol) yaitu sebesar 0,56±0,18 g, sementara tingkat kelangsungan hidup dan konversi pakan terbaik terjadi pada perlakuan 50 mg/L yaitu 54,3±0,38% dan 1,4±0,1.

Abstract

Snubnose pompano (Trachinotus blochii) mariculture commodity that admired in Lampung Bay due to faster growth and relatively struggle in dynamics environment changes likes floating cages. Disease infection become challenges when water quality degradation affects by tourism and mariculture activity in Lampung Bay. This research aimed to evaluate ectoparasite diversity that infect snubnose pompano and water qualities parameters at Lampung Bay. Survey conducted three times on 2022, September and October with snubnose pompano sampled amount 2.5% of population. Nine water quality variables were taken and measured in Seafarming Development Centre of Lampung. Results showed three species identified i.e. Pyragraphorus hollisae, Neobenedenia girellae and Benedenia sp. were infected snubnose pompano. Pyragraphorus hollisae dominated in intensity, prevalence while diversity index and uniformity index were low. Ammonia amount was high due to pollution and supported domination of Pyragraphorus hollisae. This research is expected to be one of the references in the treatment of ectoparasite infection in Snubnose pompano cultivation
