“…These nutrients are obtained from the characteristics of Artemia as a non-selective filter feeder, which means it does not select food and consumes anything that enters its mouth (Mohebbi et al, 2015). In addition to the nutrients present in A. franciscana as feed for shrimp larvae, this species can also be a vector for the spread of pathogens in shrimp larvae (Haq et al, 2012). Alternative prevention of pathogens can be done by giving disinfectants to suppress the emergence of bacteria, viruses, or other diseases, such as iodine.…”

Artemia franciscana nauplii is a source of nutrients and pathogen vectors due to the non-selective nature of the filter feeder. Prevention of pathogens is done by adding iodine disinfectant to suppress the emergence of bacteria. One way to find out if a substance is toxic is by testing the toxicity and lethal concentration (LC50) on A. franciscana nauplii. The aim of this study was to evaluate the disinfectant effect of iodine and determine the lethal concentration of iodine in 50% of A. franciscana nauplii (LC50). Brine Shrimp Lethality Test (BSLT) method using Artemia as test animal. The results of the toxicity test with several doses of iodine showed that the toxic threshold value for 96 hours was 20.31 ppm. The results were supported by the presence of stunted growth at a dose of 100 ppm by measuring the length and weight. The conclusion of this study is that the administration of iodine at several concentrations is toxic to A. franciscana nauplii if it exceeds 20.31 ppm and affects the growth of A. franciscana nauplii.

“…After 8 h of incubation, the Artemia nauplii were collected using sterile Miracloth, and washed with 1 mL sterile saline solution (0.85 %, NaCl), then macerated using a homogenizer (LabGEN ® 125, Cole-Parmar, USA). To estimate bacterial concentration in the tissues, the homogenate suspensions were serially diluted in sterile saline until dilution factor 10 -9 (Badhul Haq et al, 2012). A 100 µL aliquot was pipetted and spread-plated on de Man Rogosa and Sharp agar (MRS, Difco TM BD, USA), then followed by incubation at 26 ± 2 °C for 24-48 h. The experiment was performed in triplicates.…”

Aims: This study aimed to investigate the suitability and efficacy of various encapsulation media in bioencapsulating the probiotic Lactococcus lactis subsp. lactis in Artemia franciscana nauplii. The impact of the encapsulation media on nauplii survival and probiotic recovery was also determined. Methodology and results: Various encapsulation media (sodium alginate, palm oil, starch, gum Arabic and gelatin) were prepared by dissolving the respective media in artificial sea water. Each media was prepared in four different concentrations: 0.25, 0.5, 1.0 and 2.0 g/L. To determine the suitability of encapsulation media on the survivability of A. franciscana, survival rate (SR) of Artemia nauplii was determined after 8 hours post-encapsulation. Instar II stage Artemia nauplii at 1 nauplii per mL was used for each replicate. The result revealed that A. franciscana reached 100 % SR in the encapsulation media at ≤ 0.5 g/L. All media enabled > 23 % recovery of L. lactis subsp. lactis from encapsulated A. franciscana, which is similar (p > 0.05) to the recovery of free-cells (non-encapsulated) of L. lactis subsp. lactis. Noticeably in sodium alginate (E1) treatment, the total counts of L. lactis subsp. lactis in bioencapsulated A. franciscana were the highest among others, accounting for 2.44 × 10 7 CFU/mL per A. franciscana tissue homogenate. Conclusion, significance and impact of study: Artemia nauplii bioencapsulated with L. lactis subsp. lactis using 0.5 g/L sodium alginate as encapsulation medium has the highest SR for nauplii and bioencapsulation efficiency, respectively. This result provides a basic guideline for Artemia bioencapsulation in fish/shrimp larval culture.
