REPRODUCTIVE BIOLOGY AND FISH SHOWERING TECHNIQUES

Reproductive Biology

Reproductive Biology is considered the science that studies life. The reproductive system in living things is one of the systems that greatly affect human survival. Studying the reproductive system, it is not only limited to anatomy but also studies its functions and interrelationships in human life. This book is made so that readers understand the structure of reproductive biology with an emphasis on the integration of science and practice in midwifery.

The Reproductive Biology textbooks contain several things about biology, as well as the human reproductive system. The discussion in this book is structured based on the GBPP and D-3 midwifery curriculum in a communicative manner so that readers can be more receptive to the content presented.

About Reproductive Biology

This study aims to examine the reproductive biology aspects of kebali fish (Oesteochilus schlegeli Blkr) which include the relationship between length and weight, sex ratio, gonadal maturity level (TKG), gonadal maturity index (IKG), fecundity and egg diameter. Fish samples were obtained from the catch of fishermen in the Kapuas River (Kubu Raya Regency) and S. Sekayam (Sanggau Regency), West Kalimantan for six months (from March to August).

The results showed that the kebali fish from both waters had isometric and allometric growth patterns, where the fish from S. Kapuas was fatter (b = 2.908) than the kebali fish from S. Sekayam which had a value of b = 2.652. The sex ratio of fish was close to 1 : 1 and did not show a significant difference between fish living in S. Kapuas and S. Sekayam. The gonadal maturity level of kebali fish in the transition season (shown from the rainy season to the dry season) is from TKG I to IV, while in the dry season it is dominated by fish from TKG I.

The gonadal maturity index of kebali fish in the transition season is higher than the dry season. The fecundity of kebali fish is spread over a wide range, with a range of 168 to 2,365 grains. Water quality at the time of sampling, such as temperature 29.0–30.7°C, dissolved oxygen in Kapuas River 5.01 mg/L and S. Sekayam 5.11 mg/L.
