The survival rate of PIT tagged fish was investigated for five Korean Cyprindae fish species, Acheilognathus lanceolatus (n=18, total length : $92.5{\pm}13.1mm$; body weight : $9.6{\pm}4.3g$), Hemibarbus labeo (n=28, TL : $220{\pm}74.4mm$; BW : $91.8{\pm}76.2g$), Zacco koreanus (n=13, TL : $116.5{\pm}23.8mm$; BW : $13.6{\pm}10.6g$), Zacco platypus (n=108, TL : $100.6{\pm}17.8mm$; BW: $8.7{\pm}4.8g$), Opsariichthys uncirostris amurensis (n=6, TL : $161.8{\pm}26.3mm$; BW : $27.5{\pm}18.3g$) with respect to applicability and effectiveness of PIT tagging. The survival rate were daily checked for 30 days. The survival rate was the highest and lowest for Z. koreanus and Z. platypus, respectively. The survival days were greater as fish total length increased. Based on these results, PIT tagging is not effective for Z. platypus, while PIT tagging for fish>150 mm was effect for field research.

The objective of this study was to evaluate survival rate and fish movement (migration) using a tagging approach of passive integrated transponder (PIT) in Juksan Weir, which was constructed as a four major river restoration projects. For this study, survival rates of each fish species and the mobility of fish individuals were analyzed during 2 weeks by the insertion of PIT tags to various fish species in the laboratory. According to tagging tests in the laboratory, the survival rate 37.5% (30 survivals of 80 individuals) after the insertion of PIT tags. The survival rate of Carassius auratus and Hemibarbus labeo was 100% and 80% after the insertion of the tags, respectively, whereas it was only 13.3% for Zacco platypus. In the field experiments of Juksan Weir, 6 species and 157 individuals from 8 species (563 individuals) were detected in the fixed automatic data-logging system, indicating a detection rate of 27.9% in the fishway of Juksan Weir. In the meantime, some species with no or low detection rates in the fixed automatic data-logging system were turn out to be stagnant-type species, which prefer stagnant or standing water to live.

The passive integrated transponder (PIT) telemetry is a useful method for investigating fish population dynamics, community structure and migration. It can be applied for small fishes (TL<100 mm) because of its tiny size and light weight. The survival rate of PIT tag was investigated on 4 small size cyprindae fish species, Carassius gibelio langsdorfi (n=34, standard length; $91.9{\pm}0.9mm$, body weight; $21.2{\pm}0.9g$), Hypophthalmichthys molitrix (n=16, SL; $75.1{\pm}0.9mm$, BW; $6.0{\pm}0.2g$), Pseudorasbora parva (n=30, SL; $51.4{\pm}1.1mm$, BW; $2.7{\pm}0.2g$) and Phoxinus phoxinus (n=37, SL; $70.6{\pm}1.4mm$, BW; $8.2{\pm}0.5g$) under age 1 for applicability and effectiveness. We used three type tags including a small (length 11.0 mm, diameter 2.1 mm, weight 0.088 g), middle (20 mm, 3.5 mm, 0.102 g), large (30 mm, 3.5 mm, 0.298 g) size. After 30 days of tag insertion, survival rate of 117 individuals were 58.1% (large tag, 50.0%; middle tag, 57.5%; small tag, 61.4%). Survival rates varied between three types of tags because the abdominal cavity of each individual was different size. The death was due to surgical damage. If we apply tagging systems on field research of the Korean freshwater fish, the PIT tag will be effective method for analyzing fish ecology.
