Abstract

AbstractGrowth of fish is affected by environmental conditions. As growth pattern is reflected on the growth ring pattern in the otolith, growth pattern variations caused by environmental condition will also be reflected in the growth ring pattern in the otolith. Mudskipper was present in 2 different areas namely in the mangrove ecosystem and around the harbor area.  To understand the growth ring pattern of the fish from those areas, a study has been conducted on August to October 2018.  Fifty seven fishes were captured, 32 fishes (15 males and 17 females, 135-215 mm of TL, 16-185 g of BT) from the mangrove and 25 fishes (9 males and 6 females, 150-230 mm of TL, 35-141 g of BT) from the harbor. The otolith was removed, processed, and growth ring pattern was checked using a binocular microscope. Results shown that dark growth ring pattern in the fish from the harbor and mangrove was different. The mangrove fishes has 1-4 dark growth ring, while the harbor fishes have 2-9 dark growth ring . The quantity of dark ring in otolith shown that the fish from the mangrove grew better than the fishes from the harbor.Keywords :environmental conditions, otolith ring, amphibious fish, growth pattern.

ABSTRACT The research was conducted on 19-29 July 2017 in the Pongkai Istiqomah Village Lake District XIII Koto Kampar Kampar Regency, Riau Province. The purpose of this study was to determine the effect of different types of lure on the catch of longline fishing gear. This type of lure is to be used in the waters of the Pongkai Istiqomah Village Lake District XIII Koto Kampar, Kampar Regency, Riau Province. The feed factor is very influential on the catches. The feed used (both type and size) must be able to provide stimulation for fish and other catches to approach and eat the bait (Boesono et al. 2012). The result of catches using paweh lure (Osteochilus hasselti) (Feed 1) is as many as 22 tails. The most catches using paweh lure (Osteochilus hasselti) (Feed 2) are on the 6 day of many as 4 tails. While the least results are on days 1 and 7 with the result that no fish are caught. The catches using Siban fish lure(Cyclocheilichthys apogon) (Lure 2) were as many as 14 tails. The catch using this bait has an average catch of 2 tails. While the catch using the catfish (Peristolepis grooti) lure (Lure 3) is 7 tails. The most catches are on the 8 day, which is as much as 2 tails. The types of catches during the research is Baung, Toman and Pufferfish.Keyword: lure, longline, longline catches
