Evaluation of Dry Pellet on Growth of Juvenile Korean Rockfish (Sebastes schlegeli) by Comparing with Moist Pellet and Raw Fish-Based Moist Pellet

Journal of Aquaculture (1996)

Sang‐Min Lee Jeon Im-Gi

Two experiments were conducted to evaluate dry pellet on growth of juvenile Korean rockfish (sebastes schlegeli) by comparing with moist pellet and raw fish-based moist pellet. In the first experiment, three replicate groups of 40 fish averaging 4.7 g were fed one of the following three experimental diets for 11 weeks : d교 pellet (DP) and moist pellet (MP) diets containing white fish meal (WFM) + soybean meal (SM) + corn gluten meal (CGM) as protein sources, or raw fish-based moist pellet (RMP, frozen horse mackerel+ commercial fish feed). No significant differences were found among fish fed different pellet types of diets in daily weight gain and whole body composition (P>0.05). In the second experiment, two replicate groups of 140 fish averaging 10.9 g were fed one of the following three experimental diets for 8 weeks : DP and MP diets containing WFM+ SM+ CGM as protein sources, or RMP. Daily weight gain and feed efficiency from fish fed RMP were significantly (P>0.05) higher than those from fish fed DP diet. These different growth responses between two experiments may be due to dietary protein sources and nutrient content. findings showed that DP can be used as a practical diet for juvenile Korean rockfish.

Growth of Juvenile Sea Cucumber Apostichopus japonicus in Integrated Culture with Rockfish Sebastes schlegeli or Abalone Haliotis discus hannai

Korean Journal of Fisheries and Aquatic Sciences (2014)

Jin Choi Sang‐Min Lee

A feeding trial was conducted to investigate the growth and body composition of juvenile sea cucumber Apostichopus japonicus in integrated culture with abalone Haliotis discus hannai or rockfish Sebastes schlegeli. Triplicate groups of sea cucumber averaging $1.2{\pm}0.05g$ were cultured alone or with abalone or rockfish for 12 weeks. Survival of sea cucumber was not affected by co-culturing (P>0.05). Weight gain of sea cucumber cultured with rockfish was significantly higher than that of sea cucumber cultured alone (P<0.05), and did not differ from that of those cultured with abalone (P>0.05). These findings indicate that co-culturing sea cucumber with rockfish effectively improves the growth of sea cucumber.

Sang‐Min Lee Jeon Min Jee Kim Dae Hee

A feeding experiment was conducted using juvenile abalone (Haliotis discus hannai) to investigate the optimum level of supplemental vitamin and/or mineral premixes in a formulated diet for practical feed formulation. Three replicate groups of abalone averaging 100 mg were fed the diets containing different levels of vitamin premix ( and ) and /or mineral premix( and ) for 4 months. Survival rates of abalone showed no distinctive trend by the levels of dietary vitamin premixes. Weight gain, shell growth and soft body weight of abalone were not significantly affected by the different dietary vitamin and/or mineral premixes (P>0,05). Moisture, protein and lipid contents of soft body were influenced by experimental diets (P

Evaluation of the Nutrient Digestibilities by Different Fecal Collection Methods in Juvenile and Adult Korean Rockfish (Sebastes schlegeli)

Korean Journal of Fisheries and Aquatic Sciences (1997)

Sang‐Min Lee

The apparent nutrient digestibilities were examined by using chromic oxide indicator according to the various fecal collection methods in juvenile and adult Korean rockfish (Sebastes schlegeli). Feces were collected from three replicate groups of fish by dissection, stripping or decantation using fecal collector attached to fish rearing tank, respectively. The digestibilities of dry matter, protein, lipid, and energy were affected by fecal collection methods (P0.01). The digestibilities of dry matter, protein, lipid, energy, nitrogen-free extract, and total amino acids in juvenile and adult fish were 58, 93, 94, 79, 32, and , and 61, 94, 96, 80, 29, and , respectively, when they were measured by decantation method. Methionine, cystine and valine digestibilities were significantly lower than those of other amino acids in both juvenile and adult fish (P

Effect of Feeding Frequency of Extruded Diets Containing Different Macro-nutrient Levels on Apparent Nutrient Digestibility in Grower Flounder Paralichthys olivaceus

Journal of Aquaculture (2005)

Joo-Young Seo Kyoung-Hyun Choi Jin Choi Sang‐Min Lee

Two feeding trials were carried out to investigate apparent nutrient digestibility of flounder fed experimental diets containing different levels of macro-nutrients by satiation feeding rate (Exp-1) and feeding frequency (Exp-2). Triplicate groups of fish averaging 280 g were fed three experimental diets which contained different levels of carbohydrate, protein and lipid by two feeding regimes (satiation and 80% satiation) and four feeding frequencies (three meals a day, two meals a day, one meal a day and one meal every two days). Feces were collected using a fecal collection column attached to fish rearing tanks for 6 weeks. Apparent digestibilities of dry matter, protein, lipid, energy and carbohydrate were not affected by feeding satiation rate in Exp-1. Apparent protein digestibility was not affected by feeding frequency, whereas affected by dietary composition in Exp-2. Apparent protein digestibility of fish fed a high-protein diet showed a tendency to become higher compared to that of fish fed high-carbohydrate diet and high-lipid diet at the same feeding frequency. Apparent lipid digestibility was not affected by dietary composition, however, affected by feeding frequency. Apparent digestibilities of energy and carbohydrate were affected by both dietary composition and feeding frequency. Apparent digestibities of energy and carbohydrate in fish fed the high-protein diet showed a tendency to become higher compared to that of fish fed the high-carbohydrate diet and high-lipid diet at the same feeding frequency. Apparent digestibities of energy and carbohydrate tended to decrease with increasing of feeding frequency at the same dietary composition.

Effects of Dietary n-3 Highly Unsaturated Fatty Acids and Vitamin E Levels on the Growth and Fatty Acid Composition of Rockfish Sebastes schlegeli

Fisheries and aquatic sciences (2010)

Sang‐Min Lee

Faculty of Marine Bioscience and Technology, Gangneung-Wonju National University, Gangneung 210-702, Korea A feeding trial was conducted to investigate the effects of different levels of dietary n-3 highly unsaturated fatty acids (HUFA) (1.1-5.6%) and vitamin E (70 and 400 mg/kg) on the growth and body composition of juvenile rockfish. Six isonitrogenous (45% crude protein) and isolipidic (17% crude lipid) diets were formulated to contain graded levels of n-3 HUFA and vitamin E. Diets 1, 2 and 3 consist of 400 mg vitamin E/kg diet with graded levels of 1.1, 3.0, and 5.6% n-3 HUFA, respectively. Graded levels of n-3 HUFA (1.1, 3.0, and 4.0%) were added in diets 4, 5 and 6, respectively, containing 70 mg vitamin E/kg diet each. At the end of feeding trial, growth performance of rockfish was affected by neither dietary n-3 HUFA nor vitamin E levels. Feed efficiency and hepatosomatic index were slightly decreased (P<0.05) with increment of dietary n-3 HUFA at each dietary vitamin E level. Dietary vitamin E and n-3 HUFA levels did not affect proximate composition and vitamin E concentration in the dorsal muscle of rockfish. Liver moisture and crude protein contents positively related to dietary n-3 HUFA levels. Liver lipid content and hematocrit value were significantly decreased (P<0.05) by increasing dietary n-3 HUFA levels. Eicosapentaenoic acid (20:5n-3; EPA) and docosahexaenoic acid (22:6n-3; DHA) concentrations in the dorsal muscle significantly correlated to dietary n-3 HUFA levels, except for fish fed the diet 6 containing 4% n-3 HUFA and 70 mg vitamin E/kg diet. EPA concentration in the dorsal muscle of fish fed the diet 6 was significantly lower than that of fish fed the diets 2, 3 and 5. The present findings suggest that feeding of diets containing excessive n-3 HUFA level with varying addition of vitamin E may alter fatty acid composition in the dorsal muscle, but do not affect growth of juvenile rockfish.

Effect of Dietary Lipid Level and Herb Mixture on Growth of Parrot Fish, Oplegnathus fasciatus

Korean Journal of Fisheries and Aquatic Sciences (2003)

J.H. Kim Sang‐Min Lee Jae-Min Baek Jae-Kwon CHO Dong S. Kim

A feeding trial was carried out to Investigate the effect of lipid level and herb mixture in the diets on growth of juvenile parrot fish, Oplegnathus fasciatus. Two plicate groups of fish averaging 4.5 g were fed four experimental diets containing herb mixture (0 and 5 g/kg diet) at each of two lipid levels $(8\%\;and\;16\%)$ for 8 months from summer to spring (water temperature, $7.2-25.4^{\circ}C)$. Weight gain improved with increasing dietary lipid level or supplementation of herb mixture during the first 4 months feeding period. Weight gain of fish fed the diet containing $16\%$ lipid level was significantly higher (P<0.05) than that of fish fed the diet containing $8\%$ lipid level. Weight gain of fish fed the diet with herb mixture was significantly higher (P<0.05) than that of fish fed the diet without herb at the $16\%$ lipid level. Feed efficiency was influenced by dietary lipid level or herb mixture during the first 4 months. On the other hand, weight gain and feed efficiency were not affected by dietary lipid level and herb mixture after 4 months until end of feeing period. Survival of fish fed the diet containing $8\%$ lipid without supplementation of herb mixture was the lowest among the groups (P<0.05). Lipid contents of liver and viscera tended to increase with increasing dietary lipid level during the first 4 months feeding period, however muscle lipid content was not influenced by dietary lipid and herb. Total cholesterol of serum was influenced by dietary lipid level during the first 4 months feeding period. These results indicate that an increase of dietary lipid level from $8\%\;to\;16\%$ and supplementation of herb mixture can improve growth performance of juvenile parrot fish when water temperature is optimum for growth such as the summer season in Korea.
