 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Studies on the Relationships of Mineral Elements in Mud, Water and Blood of Walking Catfish, Claries batrachus(Linnaeus) in the Fishpond in Nakhon Pathom, Lop Buri and Supha ผู้เขียน: นางส่งศรี มหาสวัสดิ์, รองศาสตราจารย์ , นายชัยชาญ มหาสวัสดิ์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe Relationships between the mineral elements in mud, water and in the blood of the walking catfish Clarias batrachus (Linnaeus) were studied. The samples were collected during January to August of 1985 from three provinces, Nakhon Pathom, Lop Buri and Suphan Buri. Nine mineral elements, including sodium (Na), potassium (K), iron (Fe), zinc (Zn) Magnesium (Mg), manganese (Mn), calcium (Ca), phosphorus (P) and copper (Cu) were analyzed. The result showed that the concentrations of mineral elements in the mud and water sample were not different. The amount of the mineral elements in the walking catfish blood was high. The information obtained from walking catfish blood could be used as a guideline for the future research on the mineral elements in the aquatic animals. |

หัวเรื่อง:การจับสัตว์น้ำโดยใช้อวนติดสามชั้นต่างสีภายใต้อิทธิพลของข้างขึ้นและข้างแรม ผู้เขียน:นายชัยชาญ มหาสวัสดิ์, รองศาสตราจารย์, นายลิขิต ชูชิต สื่อสิ่งพิมพ์:pdf AbstractAn experiment of the catches of fish by white, green and violet trammel nets at the depth of 3 meters, was conducted at night around Sriracha Bay at Sriracha Fisheries Research Station during 2-3 days before and after full moon and new moon in June to September, 1987. Factorial experiment in randomized block design was engaged. The results revealed that the catch efficiencies of white, green and violet trammel nets show no significant differences upon the lunar periodicity. In the full moon night, a large number of silver biddy ( Gerres filamentosus ) was caught with highly significant against pony fish ( Leiognathus brevirostris ) and swimming crab ( Portunus pelagicus ) . In the new moon night, a lot of silver biddy and swimming crab were caught with highly significant against pony fish. The efficiency of white trammel net was the best in full moon operation for shrimps and cephalopod and the efficiency of green trammel net operation was the best for aquatic animals even though they showed no significant differences among the three colour of them. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : A Study on Species Compositions and Morphological Changes of the Fish Larvae in Brackishwater) ผู้เขียน:สืบสิน สนธิรัตน, นายสุจินต์ ดีแท้, ผู้ช่วยศาสตราจารย์, นายชัยชาญ มหาสวัสดิ์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractA study on species compositions and morphological changes of the fish larvae was conducted for two years and the work was done at the mouth of the Klong Wan Canal; Prachuab Khirikhan Province, and the laboratory of the Faculty of Fisheries, Kasetsart University in Bangkok. From this study, there were at least 34 species but fairly good information was obtained only from the larvae of Chanos chanos, Megalops cyprinoidies and Therapon jarbua. The results were shown in Table 1 and Table 2 in which temperatures and salinity of water during the periods of collections were added. Morphological changes, however, were shown in Plate 1, 2 and 3. The changes of the larvae of Chanos chanos, Megalops cyprinoides, and Therapon jarbua took about 60, 50 and 21 days after collected , respectively. |

หัวเรื่อง:การเปลี่ยนแปลงคุณสมบัติของเลือดและส่วนประกอบไอออนของพลาสม่า ในปลาดุกด้านที่เป็นโรคเชื้อแอร์โรโมนาส ไฮโดรฟิลล่า ผู้เขียน:Songsri Manasawasde, Chaichan Manasawasde สื่อสิ่งพิมพ์:pdf Abstract Hematological studies on catfish, Clarias batrachus (Linnaeus) were conducted by injecting the fish with Aeromonas hydrophila at 5.6 x 10??, call ml-?, while the 0.6 ml. control saline solution was applied for the control one. The results shoe that, the infected fish with A. hydrophila were significasing trend in hematocrit value at 95%. Hemoglobin concentration, total crythrocyte, counts and mean corpuseular hemoglobin concentration (MCHC) from the infected fish with 19.6 x 10?? cells ml-?, were significant lower than the control value. There no statistic different in total leucocyte counts, differential leucocyte (neutrophil, lymphocyte and thrombocyte) , plasma Na+ and K+ in vitro. |
หัวเรื่อง:ประสิทธิภาพของไฟใต้น้ำในเครื่องมือลอบ ผู้เขียน:Chaichan Mathasawasde สื่อสิ่งพิมพ์:pdf AbstractThe experiment on the use of cylindrical flapsible fishing traps to catch the aquatic animals at Si Racha Bay, Changwat Chon Buri was carried out between May to August, 1989, at the depth of 7 meters. The study was divided into 4 treatments; the three colours of underwater luring lamps, red, yellow, green, and squid bait were used for luring. The results revealed that, the swimming crab, Portunus pelagicus, entered only in the red lamp traps 1.3% of the whole total weight. The squid bait traps gained 65% of catch. The percentage of fishes caught by red lamp, yellow lamp, green lamp and squid bait traps were 4.2, 4.4, 3.2 and 21.9% by total weight of catch respectively. |
