The Addition of Lemuru Fish Oil in Bran Suspension to Successful Induction of M. macrocopa Ephippia Production

Abstract

The production M. macrocopa ephippia limited by availability of poly unsaturated fatty acids (PUFAs) in feed. The lack amount of ω-3 fatty acids in rice bran suspension limits ephippia production. Lemuru fish oil containing EPA has potential to enrich in rice bran suspension to increase ephippia production. The purpose of this study to determine the affect addition of lemuru fish oil in rice bran suspension and the optimal concentration of lemuru fish oil in rice bran suspension which results the highest ephippia production. This study used Completely Randomized Design (CRD) method with 5 treatments adding fish oil in rice bran suspension of 0%, 1.5%, 3%, 4.5%, and 6%), with 4 replications. Sexual female offspring are produced from cultures with density 660 ind /L with regulated feed concentration. Furthermore, offspring are cultured with feed according the treatment. During the culture, daily production, total production and production ephippia per parent. These results indicate addition of lemuru fish oil to rice bran suspension as feed of M. macrocopa affect the production ephippia. The addition of lemuru fish oil with concentration 6ml / 100g in rice bran produce the highest total M. macrocopa ephippia production (3452 ± 43.0 grains / Liter)

Analysis of high protein feed on the maintenance of tilapia (Oreochromis niloticus) broodstock in brackishwater culture

“…This value was lower when compared to the results of [25] study which obtained an optimal relative weight growth of 0.05%. Calculations were obtained from the formula Zenneveld et al, [26]; Loekman et al, [27]; Oktaviani et al, [28].…”

Enhancement of protein, lipid and fatty acids in copepod, Oithona rigida for the improvement of growth, development and survival of early‐stage mud crab larvae ( Scylla olivacea )

“…The exploration of agriculture waste such as rice bran as possible food to enhance the nutritional efficiency of aquatic animals in particular as a live feed enhancement to improve fish and shellfish larvae development and survival, which indirectly contributed to the food quality management and concluded that rice bran is ideal for live feed cultivation that provides several nutrients and energy sources, including protein (12-13%) and lipid (16-20%) (Damayanti et al, 2020;Mubarak et al, 2020Mubarak et al, , 2017Oktaviani et al, 2020;Yuslan et al, 2022). The levels of protein and lipid in N. oceanica were also recorded in the range of the previous research documented protein which (50-55%) protein and (24-27%) lipids (Hulatt et al, 2017;Tibbetts et al, 2017).…”

Concentration Of Honey As A Coating In Dry Storage on Ephipia Hatchability and Survival rate of Moina macrocopa nauplii

“…M. macrocopa can produce dormant eggs called ephippia, these eggs are the result of sexual reproduction of M. macrocopa. Ephippia production technology has been developed with a combination of environmental and feed manipulation (Mubarak et al, 2017;Oktaviani et al, 2020). Ephippia can be hatched at any time and stored dry just like Artemia cysts.…”
