This research was carried out because the information related to the size of fish capture and the status of exploiting S. boops was still very little, especially in the waters around Bitung. The appropriate size of capture and exploitation status can be used as a reference to assess whether the utilization of S. boops resources in the waters around Bitung is in accordance with the sustainable management guidelines for fish resources. This study aims (1) to get the size of the first caught fish (Lc); (2) get the size of fish first cooked gonad (Lm); (3) obtain S. boops business status. The sampling of fish was obtained from the Bitung coastal fishermen who landed his catch at the Bitung Ocean Port. Retrieval of fish sample data was carried out from February 2016 to January 2017 with a total samples 1,659 using the survey method. The results showed that the size of first captured 15.10 cm FL while the size of the first matured obtained 16.30 cm FL. The status of exploitation based on the comparison of Lc and Lm parameters that percentage of matured and the SPR value categorized as overfishing.

Abstrak Penelitian ini bertujuan untuk mengetahui pola pertumbuhan, nisbah kelamin, faktor kondisi, dan struktur ukuran ikan S. boops yang tertangkap di perairan sekitar Bitung. Penelitian dilakukan di Pelabuhan Perikanan Samudera Bitung pada bulan Februari-Juli 2016. Sampling ikan S. boops yang dianalisis berjumlah 846 ekor terdiri dari 430 ekor (50,83%) jantan, 357 ekor (42,20%) betina serta 59 ekor (6,97%) yang tidak teridentifikasi. Kisaran panjang cagak (FL) antara 8,60-23,60 cm (rerata 16,45 ± 3,34 cm) dan bobot tubuh berkisar 10,00-257,50 g (rerata 91,71 ± 56,07 g). Hubungan panjang bobot ikan S. boops keseluruhan W=0,0115 FL3,1596 (R2 = 0,9902) dengan pola pertumbuhan allometrik positif (b>3). Persamaan hubungan panjang bobot ikan S. boops jantan dan betina masing-masing adalah W=0,0105 FL3,1922 dan W=0,0107 FL3,1816 dengan pola pertumbuhan yang sama, yakni allometrik positif (b>3). Rasio kelamin S. boops jantan dan betina dalam kondisi seimbang. Kisaran faktor kondisi relatif (Kn) ikan jantan 0,7549-1,1782 (rerata 1,0018 ± 0,0596) dan ikan betina 0,6353-1,2529 (rerata 1,0024 + 0,0692) yang menunjukkan tubuh ikan kurang pipih. Sebaran frekuensi panjang ikan S. boops jantan didominasi pada interval kelas panjang 20,0–21,0 cm dan ikan betina pada interval kelas panjang 14,0-15,0 cm..Keywords: faktor kondisi, nisbah kelamin, pola pertumbuhan, Selar boops, struktur ukuran ikan Abstract This research aims to find the growth pattern, sex ratio, condition factor and size structure of S. boops caught from Bitung waters area. This research was conducted between February 2016 and July 2016, sampling location at Bitung Oceanic Fishing Port. 846 of S. boops samples fish were analised consist 430 of male (50,83%), 357 of female (42,205) and 59 un-identified (6,97%) with 8,60-23,60 cm ranges of fork length (mean 16,45 ± 3,34 cm) and 10,00-257,50 g ranges of body weight (mean 91,71 ± 56,07 g). Common equation of length-weight relationship was W=0,0115 FL3,1596 (R2 = 0,9902) with positive allometric (b>3). Equations of length-weight relationship was W=0,0105 FL3,1922 for male, while female was W=0,0107 FL3,1816 with positive allometric (b>3). Sex ratio of male and female were constant. Relative condition factor (Kn) of male was 0,7549-1,1782 (rerata 1,0018 ± 0,0596), while female was 0,6353-1,2529 (rerata 1,0024 + 0,0692), in other words that the body of S. boops was fusiform. The length frequency distribution for male S. boops was 20,0–21,0 cm and female was 14,0-15,0. Keywords: condition factor, sex ratio, growth pattern, Selar boops, fish size structure

Technological developments have encouraged the growth of various industries, which on the onehand can increase economic growth, but on the other hand, it can also cause environmentaldamage as a result of negative impacts resulting from waste generated. The coastal and marinewaters of Bitung City are industrial dense areas which are spread from the northern to thesouthern region. Besides that there were activitied which adding to the increasingly denseactivities in the coastal waters of Bitung City like the ferry port, cargo and container ports, andpassenger port. The research aims to analyze the level of pollution of mercury heavy metals(Hg), lead (Pb), and cadmium (Cd) in several types of fish consumption from Bitung waters; toget the dominant type of heavy metal exposed to fish meat; and determine the level of heavymetal contamination in the waters around Bitung based on bio-indicators.The results ofresearch showed that all fish samples were contaminated by heavy metals and each location forsampling levels of metal contamination based on bio-indicators was different, where the watersof Kampung Pisang have a higher level of metal contamination.

Abstract–Bigeye scad resources which landed at Bitung Oceanic Fishing Port is one of important fish capture in Bitung because its have economic value and second ratings after scad mackerel in product volume. Bigeye scad fish capture was often mixed with another species in fisherman fish capture, so it making difficult to distinguish clearly.The objective of this research are : 1) to indentification bigeye scad in morfology, 2) to analyzemolecular bigeye scad, (3) to evidence the bigeye scad are the same species or not.Sample for the study were collectedfish landing site at Bitung Ocean Fishing Port from December 2015 to March 2016. The methodology of the research is survey research. For data analysis using truss morfometrics, principal component analysis (PCA) and mtDNA region COI. The result of this research indicated that based on the analysis of morphometric characters and PCA, bigeye scad and smalleye scad have differences in morphology, but result of mt DNA-COI analysis indicated those species are the same as Selar crumenophthalmus with similarity value 99,67%. Keywords: bigeye scad, morfometric, mtDNA-COI

Selar boops is a group of small pelagic fish in the Carangidae family, this fish is known by the Bitung people as Tude Batu. This fish has economic value which is caught by fishermen in the waters around Bitung City using hand line fishing. This study aims to identify the secondary sexual organs. Fish samples were collected from 2 locations, namely Kampung Pisang and Pasar Winenet. The secondary sexual organs are identified by observing the morphological using the morphometric truss method of 19 morphological characters. Anova K-Means Cluster (AKMC) analysis as well as discriminant analysis were used to differentiate male and female fish groups. The results of this research showed that the morphometric characteristics of secondary sexual organs in male and female S. boops. The results showed that there were 11 different morphometric truss for morphometric characters in secondary sexual organs of male and female S. boops using AMKC analysis. The results of the discriminant analysis showed that the characteristics of the secondary sex organs in S. boops fish were found in the ratio of pectoral fin length (PaSiPek) and head length (PaKe) with a discriminant value (D) <0 grouped as male fish and discriminant value (D)> 0 classified as female. Keywords : discriminant, morphometry, secondary sexual organs, tude batu
