“…Vibrio anguillarurn and other pathogenic Vibrio species isolated from cultured fishes in Japan have also been found to be sensitive to sodium nifurstyrenate (Ogawa et al 1982). All Vibrio strains isolated from rotifers (Brachionus plicatilis) were likewise found sensitive to the drug, with MICs at 0.1 to 1.6 pg ml-' (Tanasomwang & Muroga 1989) which are much lower than values obtained in this study.…”

The minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) of 24 drugs for luminous bacteria Vibrio harveyi and V. splendidus were determined. Only chloramphenicol, sodium nifurstyrenate and the nitrofurans (furazolidone, nitrofurazone, nitrofurantoin and Prefuran) showed relatively low MICs and MBCs (< 25 pg ml-l). The bacteria showed varied responses to chloramphenicol and Prefuran, and low sensitivity to oxytetracycline. Chloramphenicol, oxytetracycline and Prefuran are commonly used in shrimp hatcheries. Shrimp larvae showed high survival rates and active swimming movement after 24 h exposure to in vivo bactericidal doses of chloramphenicol, Furacin, nitrofurantoin (protozoea only), oxytetracycline (nauplius only). Prefuran (mysis only) and sodium nifurstyrenate, but the drugs caused deformities in the carapace, rostrum, and setae. Chemical control of luminous vibriosis among shrimp larvae appears limited, based on the efficacy of existing and readily available drugs, because of the possible development of resistant strains of bacteria and the limited tolerance of the shrimp larvae to the drugs.

“…The effect of this chemothera peutant in reducing the number of vibrios in rotifers was confirmed in our previous in vestigation. 21) A distinct decrease in the in testinal bacterial numbers was observed in the rockfish when their feeds were changed from live diets to artificial diet and minced fish. Low bacterial populations in the artificial diet and minced fish as compared to the live diets must have affected the number of intestinal flora of the fish.…”

Improvement of larval rearing technique for mass seed production of snow crab Chionoecetes opilio

Larval rearing experiments were conducted to examine the potential for mass seed production of the snow crab Chionoecetes opilio using a total of eight 20-kL tanks. Tanks were equipped with agitators, which move the water using a rectangular blade to prevent the zoeas sinking to the bottom of the tank. Larval rearing water was treated with sodium nifurstyrenate once a week to reduce the chance of larval infection by pathogenic bacteria. Zoeas were fed with rotifers and Artemia nauplii. A total of 122 830 megalops and 16 660 first-stage crabs were produced. Thus, the potential for mass seed production of snow crab was determined. Survival rates up to the megalopal stage were high in tanks with a feeding regime that fed rotifers to larvae through an entire zoeal stage. This study also describes the fatty acid composition of snow crab larvae. It revealed that the first zoeas had a high DHA content and DHA/EPA ratio, but these values significantly decreased in the second stage zoeas and megalops. Improving the DHA content and/or DHA/EPA ratio of larvae should be important in studies on mass seed production technology of the snow crab.
