    Vol. 85: 187–192, 2009 DISEASES OF AQUATIC ORGANISMS Published July 23 doi: 10.3354/dao02073 Dis Aquat Org Enhanced mortality in Nile tilapia Oreochromis niloticus following coinfections with ichthyophthiriasis and streptococcosis De-Hai Xu*, Craig A. Shoemaker, Phillip H. Klesius US Department of Agriculture, Agricultural Research Service, Aquatic Animal Health Research Laboratory, 990 Wire Road, Auburn, Alabama 36832, USA ABSTRACT: Ichthyophthirius multifiliis Fouquet (Ich) and Streptococcus iniae are 2 major pathogens of cultured Nile tilapia Oreochromis niloticus (L). Currently there is no information available for the effect of coinfection by Ich and S. iniae on fish. The objective of this study was to determine the effects of parasite load and Ich development size on fish mortality following S. iniae infection. Low mortality (≤20%) was observed in tilapia exposed to Ich or S. iniae alone. Mortalities increased from 38% in tilapia exposed to Ich at 10 000 theronts fish–1 to 88% in fish at 20 000 theronts fish–1 follow- ing S. iniae exposure. The median days to death were significantly fewer (7 d) in fish exposed to Ich at 20 000 theronts fish–1 than fish exposed to 10 000 theronts fish–1 (10 d). A positive correlation (cor- relation coefficient = 0.83) was noted between tilapia mortality and size of Ich trophonts at the time of S. iniae challenge. Fish parasitized with well-developed trophonts (Day 4, 2 × 107 µm3 in volume) suffered higher mortality (47.5%) than fish (10.0%) infested by young trophonts (Hour 4, 1.3 × 104 µm3 in volume) after S. iniae challenge.

The development of fish growth model uses polynomial growth function. Profit maximization process uses the first derivative of profit equation to culture time equal to zero. This research develop the equations to estimate the culture time to reach the size target of cultured fish. This research model can be applied in the giant gouramy culture. The giant gouramy culture can produce the maximum profit at 324 days with profit of IDR. 7.847.700 per culture cycle. To achieve size target of 500 g per fish, it needs 135 days of culture time.

    Argulus ambystoma, a New Species Parasitic on the Salamander Ambystoma dumerilii from Mexico (Crustacea: Branchiura: Argulidae)1 WILLIAM J. POLY2, Department of Zoology, Southern Illinois University, Carbondale, IL 62901-6501 ABSTRACT. A new species of Argulus is described based on 18 specimens taken from the salamander ("achoque" or "ajolote") Ambystoma dumerilii Duges, collected in Lake Patzcuaro, Michoacan, Mexico. Diagnostic characters include the shape of the respiratory areas, number of sclerites in suction cup rods, and structures on the legs of males. Females are heavily stippled, whereas males have a very distinctive pigment pattern consisting of abundant melanophores covering the testes dors ally and two dark, inverted triangular patches on the carapace dorsally. The new species is similar to the North American species, A versicolor,A. americanus, A. maculosus, and A diversus. A single, dorsal pore was observed on each caudal ramus using scanning electron microscopy; these pores have not been reported previously in the Branchiura.

The range of morphological variation of A. vaillanti could thus be reassessed based on a larger number of specimens currently available in fish collections, and the species redescribed. Anchoviella vaillanti can be recognized among freshwater congeners by the relative position of the pelvic, dorsal and anal fins. Records of the species in ichthyological collections are restricted to the upper and middle portions of the Rio São Francisco basin, but the species might also occur in the lower Rio São Francisco. Comments on the distribution of the marine species of Anchoviella from the lower Rio São Francisco basin and an identification key including those species and A. vaillanti are provided.

Roberts, DVM *, Stephen A. Smith, DVM, PhD KEYWORDS Pet fish Ornamental fish Branchitis Gill Wet mount cytology Hypoxia Respiratory disorders Pathology Living in an aquatic environment where oxygen is in less supply and harder to extract than in a terrestrial one, fish have developed a respiratory system that is much more efficient than terrestrial vertebrates. The gills of fish are a unique organ system and serve several functions including respiration, osmoregulation, excretion of nitroge- nous wastes, and acid-base regulation.1 The gills are the primary site of oxygen exchange in fish and are in intimate contact with the aquatic environment. In most cases, the separation between the water and the tissues of the fish is only a few cell layers thick. Gills are a common target for assault by infectious and noninfectious disease processes.2 Nonlethal diagnostic biopsy of the gills can identify pathologic changes, provide samples for bacterial culture/identification/sensitivity testing, aid in fungal element identification, provide samples for viral testing, and provide parasitic organisms for identification.3–6 This diagnostic test is so important that it should be included as part of every diagnostic workup performed on a fish.
