Abstract

This study aimed to identify the types of parasites, prevalence, and intensity of parasitic infections in vannamei shrimp (Litopenaeus vannamei) in Teluk Mengkudu District, Serdang Bedagai Regency. The research employed a descriptive method using random sampling techniques at two traditional shrimp ponds. Shrimp samples were examined at the Zoology Laboratory, Faculty of Science and Technology, UIN Sumatera Utara. The observed organs included walking legs, swimming legs, and the tail. The results showed that three types of ectoparasites infected vannamei shrimp, namely Zoothamnium sp., Epistylis sp., and Vorticella sp. Water quality parameters indicated temperatures of 28–28.2°C, pH of 7.75–8.23, ammonia levels of 1.436–2.732 mg/L, nitrate levels of 1–1.1 mg/L, nitrite levels of 0.14–0.95 mg/L, dissolved oxygen of 0.91–3.56 mg/L, and salinity of 15.53–21.63‰. The conclusion shows that the highest prevalence was found in Zoothamnium sp. at 26%, while the highest intensity was 3.87 individuals per shrimp.   Keywords: Ectoparasite, Intensity, L. vannamei, Prevalence

Abstract

This study aims to identify the types and prevalence of parasites in tiger shrimp (Penaeus monodon) cultivated in ponds in Medan Labuhan District. Sampling was carried out at three semi-intensive pond locations with a total of 150 shrimp measuring 10-15 cm. Parasite identification was carried out through microscopic examination of the carapace, legs, and tail organs. In addition, pond water quality (temperature, pH, salinity, DO, ammonia, nitrate, and nitrite) was measured to assess its relationship with the presence of parasites. The results of the study found two types of parasitic protozoa, namely Epistylis sp and Zoothamnium sp with prevalences of 12.5% and 8.3%, respectively. Parasites mainly attach to the tail and legs which have fine hairs as attachment sites. Water quality analysis showed that ponds with low dissolved oxygen levels and acidic pH have a higher risk of infection. These findings emphasize the importance of water quality management, especially DO, pH, and nitrite to suppress parasite attacks and maintain the health of tiger shrimp.

Abstract

This study aimed to determine the effects of light color and photoperiod on body coloration and growth performance of juvenile redclaw crayfish (Cherax quadricarinatus). A total of 144 juvenile crayfish were used in an experimental design consisting of six treatments based on two light colors (red and white LEDs) and three photoperiod regimes (6, 12, and 18 hours). The observed parameters included growth performance, survival rate, and changes in body coloration. The results showed that (1) red LED treatment with a 6-hour photoperiod produced the most optimal growth, whereas the 18-hour photoperiod treatment induced stress that led to reduced growth performance; (2) red LED treatments resulted in higher survival rates compared to white LED treatments; and (3) photoperiod significantly influenced changes in body coloration, with juveniles exhibiting blue and brown pigmentation. In conclusion, photoperiod affects affected the growth of juvenile crayfish, with red LED exposure for 6 hours representing representing the optimal condition. Differences in light color contribute to improved survival rates contributed to higher survival rates, while photoperiod plays a role in influencing body color changes played an important role in influencing changes in body coloration.

Abstract

This study aimed to identify the types of ectoparasites and endoparasites infecting swamp eels (Monopterus albus). The research used a descriptive method with purposive sampling technique on 40 swamp eels collected from two different locations. Parasite examination was conducted microscopically using Semichen-Acetic Carmine staining. The results showed two types of ectoparasites, namely Ornithodorus sp. and Clinostomum sp., and three types of endoparasites, namely Diphyllobothrium sp., Ascaris lumbricoides, and Clinostomum sp. The prevalence and intensity of parasite infections varied among samples. This study concluded that environmental conditions and water sanitation influence parasite infections in swamp eels, therefore monitoring of eel consumption safety is necessary.

Abstract

This study aims to assess the diversity index, relative abundance, and evenness of soil insects in the Hutan Desa Serdang, Tahura Area, Karo District, North Sumatra. The methods used include pitfall traps and bait traps with a purposive sampling approach at three observation stations: primary forest, secondary forest, and pine forest. The results show that a total of 1,427 insect individuals were found, comprising 8 orders, 13 families, and 20 species. Odontomachus brunneus exhibited high relative abundance, followed by Entomobrya handschini and Solenopsis invicta, which fall into the category of moderate relative abundance. The diversity index of soil insects is categorized as moderate, with an value of H' = 2.0, indicating a balanced ecosystem with a sufficient variety of species. Meanwhile, the evenness index of soil insects is classified as high, with a value of H'= 0.7. This indicates a uniform distribution of species without particular dominance, thus supporting ecological balance and good soil ecosystem quality.
