  • The filtration rate and oxygen consumption of Anadara granosa bisenensis were measured at 4 different temperature (10$^{\circ}C$, 15$^{\circ}C$, 20$^{\circ}C$, and 25$^{\circ}C$) and 4 different salinity levels (20, 25, 35, and 40 psu), using an direct method under laboratory conditions. The samples were divided into two groups: a large-sized group (shell length: 34.58 ${\pm}$ 2.23 mm, body weight: 12.43 ${\pm}$ 0.44 g) and a small-sized group (shell length: 20.60 ${\pm}$ 0.85 mm, body weight: 4.41 ${\pm}$ 2.30 g). Filtration rate and oxygen consumption increased with the increase of various temperatures and salinity levels. Also, the filtration rate and oxygen consumption of the small-sized group were higher than those of the large-sized group. These results indicate that the filtration rate and oxygen consumption of Anadara granosa bisenensis depends on environmental conditions, especially on water temperature and salinity.

  • 1970년 5월, 7월, 12월에 우리나라 동해안에서 어획된 꽁치에 대해서 척추골수, 새파수 및 상대성장을 조사한 결과를 요약하면 다음과 같다. 1. 척추골수는 65개를 mode로 하고 $64\~66$게가 전체의 $90\%$ 내외를 차지하고 있으며, 평균 척추골수는 64.80이다. 새파수는 12월에 있어서 $33\~44$개의 범위에 있으며 평균치는 37.08이다. 2. 중형군($26.0\~28.0cm$대)과 대형군($30.0\~31.0cm$대)으로 구분하여 척추골수라 새파수를 보면 북상기의 중형군은 남하기의 대형군과 그 수가 닮아 있고 남하기의 중형군은 북대기의 대형군과 그 수가 닮아 있다. 3. 척추골수와 새파수와의 사이에는 상관이 보이지 않는다. 그러나, 12월에 있어서 척수골수는 대형군이 중형군보다 많으나 새파수는 중형군이 대형군보다 많다. 4. 체장에 따른 두장비의 변화는 체장의 증가에 따라 감소되는 경향이다. 5. 체장과 두장과의 관계 및 체장과 체중과의 관계는 북상기와 남하기에 따라 그 경향이 다르다. 6. 7월의 중형군에서 12월의 대형군까지의 체중 증가량은 12월의 중형군에서 7월의 대형군까지의 체중 증가량의 약 2배 이상이 될 것이라 추정된다. 7. 체장에 따른 비만도(내장 제외한 체중으로 계산)는 12월에서는 거의 일정하나, 7월의 손 꽁치 어업에서 어획되는 산란중의 군중에서는 중형군과 대형군이 상이하다. 그리고, 12월의 비만도는 7경의 비만도보다 높다.

  • The objective of this study is to evaluate the anesthetic effects of clove oil and tricaine methanesulfonate (MS-222) on the Far Eastern catfish, Silurus asotus, by measuring the times to anesthesia and recovery. Each anesthetic effect of clove oil and MS-222 was tested in two groups of fish with different body sizes: a group of small fish (mean body length: $15.5{\pm}1.58cm$, mean body weight: $50.1{\pm}5.91g$, n=20) and a group of large fish (mean body length: $31.5{\pm}4.19cm$, mean body weight: $302.1{\pm}15.22g$, n=20). The anesthetics were used at concentrations of 200, 300, 400, 500, and 600 ppm. The results showed significant relationships between the concentration of the anesthetic and the body size of the fish. Each of these variables showed statistical significance (p<0.05). The time to anesthesia decreased linearly with increasing concentration in the large fish for both clove oil and MS-222 (p<0.05). Based on an optimal anesthetic time of approximately 1 min, the preferred concentrations of the anesthetics were 500 ppm for clove oil and 600 ppm for MS-222. Both the anesthetic time and the recovery time were shorter for the small fish than for the large fish (p<0.05). Our study showed that the smaller-sized Far Eastern catfish was more easily anesthetized and recovered more rapidly from anesthesia than the larger-sized fish.

  • This study was conducted to investigate the effect of vitamin E and nanoparticle-sized vitamin E (NVE) in a broiler diet on growth performance, blood profiles, and meat quality. A total of 45 one-day-old Arbor Acres broilers (initial body weight of 37.00 ± 0.41 g) were used in this experiment for 28 days. All broilers were randomly allocated into three dietary treatments in a randomized complete block design. The dietary treatments were as follows: a basal diet (CON), a basal diet supplementing with 380 mg/kg of vitamin E (T1), and a basal diet supplementing with 380 mg/kg of NVE (T2). Each treatment had five replicates with three birds per cage. On days 0-7, the T1 and T2 groups significantly increased (P<0.05) body weight gain compared to the CON group. Also, the T1 and T2 groups significantly increased (P<0.05) vitamin E content in blood and breast meat compared to the CON group. In shearing force, the T2 group showed a lower tendency (P=0.070) than the CON group. The T1 group showed a higher tendency (P=0.086) in the b* (yellowness) value than the T2 group. On day 7 after the end of the experiment, the T2 group significantly decreased (P<0.05) TBA values compared to the CON group. In conclusion, supplementation with vitamin E or NVE can improve broiler growth performance in the starter period, reduce TBA value through the antioxidant action of vitamin E, prevent lipid oxidation, and improve shelf life.

  • To provide evidence that the changes in oceanic environmental conditions are useful indices for predicting stock structure and distribution of the Pacific saury (Cololabis saira), the body length compositions and catch per unit fishing effort were examined in relation to the sea surface temperature(SST) anomalies in the Tsushima Warm Current(TWC) region. The size of the fish became larger(smaller) than the average in the same size category during the season of higher SST(lower SST) as opposed to the normal SST. The year-to-year changes in body size caused by the changes in the environmental conditions led the stock to be homogeneous during the period of high stock level from the late 1950s to early 1970s and in the 1990s. The changes in body size manifested by higher(lower) occurrence rates of larger (smaller) sized groups in relation to temperature anomalies suggest that the changes in the environmental conditions affect the distribution and the structure of the stock in the TWC region. Therefore, if the SST anomaly derived from satellite data is large enough in the early spring months(Mar. or Apr.), it is possible to predict whether or not sea temperature will be favorable for large sized groups of saury at normal or slightly earlier time of commencement of the fishery in spring(Apr.∼June).

  • Wii® balance board (WBB) is a device that can measure and record body sway. This study was conducted to evaluate the reliability of WBB in small sized dog as inexpensive, portable and convenient tool. The center of pressure path length (CPPL) and 95% confidence ellipse area (Area 95) were evaluated with only two plates of WBB. The parameters were evaluated between no load (0 kg) and mass group (0.25-4 kg on each one plate). 23 dogs (2.3-7.3 kg) were evaluated for with hindlimb standing for 10 seconds. The mass group showed a significant value in comparison to the no load during the measurement. And intra-class correlation coefficients (ICCs) between CPPL and Area 95 revealed very high both mass and dog group. In the evaluation of medial patellar luxation (MPL) as a diagnostic tool, 80 dogs with MPL and 23 non-affected dogs were used. In studies of CPPL and Area 95, significant differences were found between non-affected and MPL groups for 10 and 30 seconds, respectively. The WBB can be used as a valid tool for evaluating hind limb standing balance and can be useful as an objective tool to present clinical results in small sized dog with MPL.

  • Interannual and decadal scale changes in body size of Pacific saury, catch and catch per unit effort were examined to investigate the environmental effects on the stock structure and abundance in the Tsushima Warm Current region. Interannual changes in thermal conditions are responsible for the different occurrence (catch) rates of sized group of the fish. Changes in body size due to environmental variables lead the stock to be homogeneous during the period of high abundance, while one of the reminder cohorts supports the stock during the period of low level of abundance. Migration circuits of two cohorts of saury stock are hypothesized on the basis of short life span and spatio-temporal changes of the stock structure in normal environmental conditions. Changes in upper ocean structure and production cycles by the decadal scale climate changes lead changes in stock structure and recruitment, resulting in the fluctuation of saury abundance. Hypothesized mechanism of the effects of climate changes on stock structure and abundance is illustrated on the basis of changes in thermal regime and production cycle.
