Two percent of monocalcuim phosphate (MCP) was added to control diet consisted of fish meal (18%), soybean meal (36%) and wheat flour (37%) in order to examine the effects on phosphorus (P) discharge and growth of carp (Cyprinus carpio). Growth trial, during which digestibility measurements were made over 7 days, was conducted for 4 weeks using a recirculated rearing system with a settling column for feces collection. Fishes (initial body weight of about 200 g) were fed five times a day upto satiation with tank controlled at $24-26^{\circ}C$. Fishes fed the diet containing 2% MCP (MCP-2) showed about two-fold improvement on both growth rate and feed utilization, compared to those of fishes fed the control diet; weight gain (129 g vs 62 g), feed conversion ratio (1.20 vs 2.46), protein efficiency ratio (2.09 vs 1.07) and daily growth index (3.70 vs 1.93). However, feed intakes were maintained at the same level (150 g/fish) between the two treatments. Dry matter digestibilities of two diets were relatively low, which were 58 and 60% for respective control and MCP-2 diets due to low digestibility of total carbohydrates. However, the digestibilities of both dietary protein (85%) and lipid (90%) of diets were relatively high. While all the P fed were observed to be discharged from fish fed control diet, the discharge from fish fed the MCP-2 diet was decreased up to less than the half (34.9 g/kg wt. gain) of the control. These present results revealed that the supplementation of dietary P requirement by MCP can not only promote growth performances but also reduce the level of P loading to water which is the primary water pollution indicator.

Our aim was to determine the effects of a citrus by-product (CBP) and CBP fermented by Lactobacillus plantarum (LP-CBP), provided as dietary supplements, on the growth performance, feed utilization, innate immunity and temperature tolerance of red seabream. A diet without inclusion of CBP or LP-CBP was used as a control and four other experimental diets were formulated to replace wheat flour by 4% and 8% of either CBP or LP-CBP (designated as Con, LP-CBP4%, LP-CBP8%, CBP4% and CBP8%, respectively). Experimental diets were fed to triplicate groups of 25 fish (initial body weight, 55.0 g) for 9 weeks. Growth performance and feed utilization were not significantly different among all the groups. Bone collagen content was significantly increased by supplementation with CBP and LP-CBP. Vitamin C concentration tended to be higher in livers of fish fed the supplements than in the control group. Myeloperoxidase, lysozyme and superoxide dismutase activities were higher in fish fed CBP or LP-CBP than in fish fed the control diet. When fish were exposed to low water temperature, cumulative mortalities of those fed CBP or LP-CBP supplemented diets were lower (29%, 33%, 34% and 33% mortalities for LP-CBP4%, LP-CBP8%, CBP4% and CBP8%, respectively) than in the control group (58%). Therefore, inclusion of either CBP or LP-CBP at up to 8% in red seabream diet brings benefits through enhanced innate immunity and better tolerance of low water temperature.

We investigated the effect of the modified starch [physical treatment, acetate (SA-1, SA-2, and SA-3), hydroxypropyl (HS), and acetylated distarch adipate] content on the physicochemical properties of fish cakes, called Eomuk in Korea, during storage at -20℃. When wheat flour (native starch, NS) was used, the moisture content decreased during frozen storage, resulting in a lower water-holding capacity and higher expressible drip. Compared with NS, adding modified starch had a lower effect on the moisture content during frozen storage. The water-holding capacity and expressible drip differed with the type of modified starch added. The expressible drip was lowest with HS; the SA-3 and HS modified starch were whiter than NS. Therefore, HS and SA-1 are suitable additives to improve the quality of frozen fish cakes.

This study examined the quality characteristics of brown sauce prepared with rice powder in place of wheat flour, which is the commonly used thickener. With regard to the general components, as the level of rice powder increased and its ratio in the stock increased, moisture decreased and crude protein, lipid, and ash increased. Reducing sugar content was 4.72% in the control group, and as the mixing ratio of stock to rice powder increased from 100:5 (S1) to 100:13 (S5) in the rice powder-added groups, reducing sugar content increased from 3.94% to 4.82%, respectively. In terms of Hunter's color values, as more rice power was added to the beurre mani$\acute{e}$, L, a, and b values increased. Thus, a sauce of a light brown color was appropriately made. For consistency, as more rice powder beurre mani? was inserted into the analyzer, flow was reduced and viscosity significantly increased. The pH of the control (CS) was 4.94, and there were no significant differences between the control and the rice powder-added groups. In sensory evaluations, color presented its highest score as 6.47 when the mixing ratio of stock to beurre mani$\acute{e}$ was 100:7 (S2). S2 also received the highest score for flavor at 6.32. Viscosity was highest in the control (CS) at 6.26, and was not significantly different from the 100:7 (S2) or 100:9 (S3) groups. Finally, the S2 group had the highest scores for taste (6.21) and overall-acceptability (6.30). In correlation analyses between the sensory characteristics, overall-acceptability as well as the color, flavor, viscosity, and taste of the brown sauce all presented comparatively high positive correlations, in which overall-acceptability and color had the highest correlation.

This study examined the effects of the dietary inclusion of Porphyra and sea tangle Laminaria japonica on the growth, feed utilization, body composition, and plasma chemistry of juvenile Korean rockfish Sebastes schlegeli. Eight hundred and forty juvenile fish averaging 5.0 g were allocated 40 fish per tank to 21 180-L flow-through tanks. Seven experimental diets were prepared: control (Con) without additive, 0.5 and 1% Porphyra extract (PE), 3% Porphyra powder (PP), 0.5 and 1% sea tangle extract (STE) and 3% sea tangle powder (STP), referred to as PE-0.5, PE-1, PP-3, STE-0.5, STE-1, and STP-3, respectively. Each additive was included in the experimental diet at the expense of the same amount of wheat flour. Each experimental diet was fed to triplicate groups of fish. The experimental diets had no effect on the survival, weight gain or specific growth rate of the fish, feed consumption, feed efficiency ratio, protein efficiency ratio, protein retention, hepatosomatic index, condition factor, moisture or crude protein content of the entire body excluding the liver or moisture, crude protein or crude lipid content of the liver. None of the plasma parameters were affected by the experimental diets. Based on these results, the dietary inclusion of Porphyra and sea tangle did not affect the growth, feed utilization, body composition or plasma chemistry of juvenile Korean rockfish.
