O objetivo deste trabalho foi determinar a densidade de estocagem ideal para o cultivo de camarão-branco, em sistema de biofloco sem renovação de água. Foram realizados dois experimentos inteiramente casualizados, com três repetições para cada tratamento. No primeiro, juvenis de camarão-branco, com peso médio inicial de 1,23±0,09 g, foram cultivados a densidades de estocagem de 833, 1.250, 1.667, 2.083 e 2.500 camarões por m³. No segundo experimento, o peso médio inicial foi de 6,32±0,7 g, e as densidades foram de 566, 833, 1.111, 1.388 e 1.667 camarões por m³. Os melhores resultados de produtividade, com médias de 9,92 e 10,77 kg m-3, foram obtidos com 1.667 e 1.111 camarões por m³, respectivamente, no primeiro e segundo experimentos. O aumento da densidade de estocagem afeta o crescimento e a sobrevivência do camarão-branco em sistema de biofloco.

“…Pada DOC-31-60, pertambahan bobot harian udang pada padat penebaran 750, 1.000, dan 1.250 ekor/m 2 , berturut-turut adalah 0,11-0,35 (0,18±0,08); 0,10-0,36 (0,18±0,09); dan 0,11-0,31 (0,18±0,07) g/hari, sementara pada DOC-61-105, pertambahan bobot harian masing-masing perlakuan adalah 0,05-0,28 (0,19±0,09); 0,12-0,33 (0,22±0,06); dan 0,10-0,28 (0,22±0,07) g/hari. Beberapa hasil penelitian menyebutkan bahwa pertumbuhan udang vaname dipengaruhi oleh padat penebaran dengan aplikasi penebaran 50-61 ekor/m 2 (Balakrishnan et al, 2011), 40-80 ekor/m 2 (Krishna et al, 2015), 150-450 ekor/m 2 (Krummenauer et al, 2011), dan 200-400 ekor/m 2 (Otoshi et al, 2007). Namun pada penelitian ini, padat penebaran antara 750-1.250 ekor/m 2 justru menghasilkan pertumbuhan udang yang relatif sama.…”

“…Semakin tinggi padat penebaran, semakin rendah sintasan udang vaname. Hasil penelitian Krummenauer et al (2011), melaporkan padat penebaran 150 ekor/m 2 menghasilkan sintasan 92,0%, kemudian diikuti padat penebaran 300 dan 450 ekor/ m 2 , masing-masing 81,2% dan 75,0%. Meningkatnya padat penebaran akan menurunkan sintasan udang vaname juga dilaporkan oleh Krishna et al (2015) dan Budidaya udang vaname dengan padat penebaran tinggi (Rachman Syah) Venero et al (2009).…”

ABSTRAKUpaya meningkatkan produktivitas lahan tambak dapat dilakukan dengan meningkatkan padat penebaran disertai dengan pemberian akuinput yang prima serta dukungan teknologi yang memadai. Tiga padat penebaran yaitu 750; 1.000; dan 1.250 ekor/m 2 , diaplikasikan pada tambak dengan luasan 1.000 m 2 dengan kedalaman air 1,8 m dilengkapi dengan sistem aerasi berupa kincir dan root blower, pompa submersible, automatic feeder, central drain dan collector drain serta Instalasi Pengolah Air Limbah (IPAL). Kapasitas sistem aerasi adalah 500 kg biomassa udang/HP. Udang dipelihara selama 105 hari. Hasil penelitian menunjukkan bahwa padat penebaran yang diaplikasikan menghasilkan bobot akhir udang yang relatif sama berkisar 15, 48-16,30 (15,78±0,45)

“…This increase was based on the internal recirculation of nutrients through the formation of new microbial biomass, which was subsequently grazed by the fish (Avnimelech 2006). The advantages of the technology in aquaculture has been well documented which includes low feed and water input (economical), less risk of pathogen introduction and diseases, more biosecurity, increased growth and survival, and hence increased crop yield (Otoshi et al 2009;Crab et al 2009;Samocha et al 1998Samocha et al , 2007Krummenauer et al 2011;Perez-Fuentes et al 2013). It also lowered the feed conversion rate by utilizing the in situ natural feed and has small footprints, hence reducing environmental impacts (Krummenauer et al 2014).…”

Biofloc is a conglomeric aggregation of microbial communities such as phytoplankton, bacteria, and living and dead particulate organic matter. Biofloc technology involves manipulation of C/N ratio to convert toxic nitrogenous wastes into the useful microbial protein and helps in improving water quality under a zero water exchange system. It may act as a complete source of nutrition for aquatic organisms, along with some bioactive compounds that will enhance growth, survival, and defense mechanisms, and acts as a novel approach for health management in aquaculture by stimulating innate immune system of animals. Nutritionally, the floc biomass provides a complete source of nutrition as well as various bioactive compounds that are useful for improving the overall welfare indicators of aquatic organisms. Beneficial microbial bacterial floc and its derivative compounds such as organic acids, polyhydroxy acetate and polyhydroxy butyrate, could resist the growth of other pathogens, thus serves as a natural probiotic and immunostimulant. The technology is useful in maintaining optimum water quality parameters under a zero water exchange system, thus prevents eutrophication and effluent discharge into the surrounding environment. Moreover, the technology will be useful to ensure biosecurity, as there is no water exchange except sludge removal. The technology is economically viable, environmentally sustainable, and socially acceptable.
