| dc.description.abstract | Sibolga is one of the areas located on the west coast of Sumatra. The main
potential of the economy comes from fisheries, tourism, services, trade and
maritime industry. The high level of fishing activity in Sibolga can be seen from
the existence of the Pelabuhan Perikanan Nusantara (PPN) and Tangkahan which
is able to accommodate fishermen's catches which are then marketed to meet
local, foreign and even export fisheries needs. This study aims to determine the
abundance and diversity of the abundance and diversity of pelagic fish
(Scombridae) in the Tapanuli waters which landed at the Sibolga Archipelago
Fisheries Port (PPN). The research method used was purposive sampling with a
sample of 150 pelagic fish landed at PPN Sibolga. The data analysis technique
used is the analysis of Relative Abundance (KR), Diversity Index (H'), Uniformity
Index (E), and Dominance Index (C). The results showed that the Diversity Index
(H') was 0.90, the Uniformity Index (E) was 0.50; Dominance Index (C) 0.53 and
Relative Abundance (KR) for Katsuwonus pelamis 70.90%, Thunnus obesus
10.93%, Thunnus albacares 0.05%, Euthynus affinis 14.46%, Auxis thazard 0.77
and Rastelliger kanagurta 2.88% | en_US |
