Perubahan Patologi Kulit Ikan Gurami (Osphronemu Gouramy) Akibat Infestasi Lernaea Cyprinacea Pada Derajat Infestasi Yang Berbeda [the Pathology Alteration of Gouramy (Osphronemus Gouramy) Integument Infested by Lernaea Cyprinacea at Different Degress of Infestation]

The development of fish consumption in Indonesia was promising increasingly and growing very rapidly. One of the priority commodities in the development of aquaculture subsector was the gourami (Osphronemus gouramy). Many factors must be faced in the cultivation of gouramy, including the problem of fish diseases caused by Lernaea cyprinacea. The aim of this research is to find out the description of anatomic pathology and histopathology of gouramy which infested by L. cyprinacea at different degrees of infestation. This research uses descriptive method. The research showed that the gouramy integument which infested by L. cyprinacea at low, moderate and heavy infestation cause moderate until heavy defect with 2.48; 2.42 and 2.32 in reaverage scoring. Hence, accordance with pathological anatomy, L. cyprinacea infestation caused necrotic nodules, lesion which covered by exudate and haemorrhage. While the histopathology of the integument changes found were inflammatory cell infiltration, congestion and haemorrhage in the low, moderate and heavy infestation

Skrining Ektoparasit pada Peternakan Itik Semi Intensif di Mojosari

Ectoparasite infestation on ducks has a collaboration with a lost production against it self. Lice on ducks, belongs to ordo Phthireptera. it belongs as a biting lice. The transmission occurs because of a direct contact. Mites on ducks, belongs to ordo Acarina, a blood sucking. The aim of this study wil know about the types of ectoparasite, which consist of lice and mite. The prevalences of ectoparasi1es on ducks were 100°A,, consist of lice (Goniocotes sp. and Co/umbicola sp) and mites Cnemidocoptes sp. and Ornithonyssus sp.). There were not given a significant level (p>0,05) for locations against ectoparasite

Prevalence and intensity of Trypanosoma sp. in wild swamp eels (Synbranchus bengalensis) marketed in Surabaya, Indonesia

Prevalence and intensity of Trypanosoma sp. in wild swamp eels (Synbranchus bengalensis) marketed in Surabaya, Indonesia. Biodiversitas 20: 3262-3268. Trypanosoma sp. is parasitic protozoa, which can infect not only aquatic organisms but also humans. As the parasite considered a zoonosis disease, there has been a lot of concern about the presence of this parasite in aquaculture commodities. This research aimed to detect and determine the prevalence and intensity of Trypanosoma sp. infection in wild-caught swamp eels (Synbranchus bengalensis) marketed in Surabaya. A total of sixty swamp eels with 47.30±4.69 cm in length were collected from two different locations, Ambengan and Karah, Surabaya, East Java, Indonesia. The swamp eels were transported alive in two aerated plastic bags to the laboratory. The observed parameters were prevalence and intensity of Trypanosoma sp. in the eels’ blood, total erythrocyte counts and total differential leucocyte count (monocytes, lymphocytes, basophils, eosinophil, and neutrophil). The result showed that 7 of 30 (23%) wild-caught swam eels obtained from Ambengan and 9 of 30 eels (30%) collected from Karah were infected by Trypanosoma sp. The intensity of the parasite in eels collected from both locations was considered as moderate, 12.6 parasites/eel (Ambengan) and 5.9 parasites/eel (Karah). Additionally, hematology analysis indicated total erythrocytes count of blood in the infected eels from both locations were significantly lower than total erythrocytes of blood in the non-infected eels, p0,05. These results demonstrate that swamp eels marketed in Surabaya were infected by Trypanosoma sp
