Abstract

Determination of heavy metal concentrations (Cd, Cu, Pb and Zn) in  different parts (muscle, bone, scale, intestine, gills and fin) of a croacker fish (S. russelli) collected from Dumai coastal waters were carried out during May to July 2009. The concentration of each metal was determined by AtomicAbsorption Spectrophotometer Perkin Elmer 3110 in the Marine Chemistry Laboratory, Marine Science Department University of Riau Pekanbaru. The results showed that Zn was found to be the highest concentrations in most of the fish body parts analyzed followed by Pb, Cu and Cd in both samples from the western and eastern regions of Dumai coastal waters. In general, the concentrations of all metals analyzed in the present study were higher in fish collected from the eastern region of Dumai coastal waters where more anthropogenic activities such as industries and human habitations along the coastal area were found. The concentration of heavy metals observed were Cd:  0.098 – 0.103, 0.189 – 0.283, 0.099 – 0.289, 0.107 – 0.302, 0.182 – 0.377 and 0.118 – 0.397; Cu: 0.130 – 0.198, 0.189 – 0.341, 0.082 – 0.073, 0.132 – 0.285, 0.520 – 0.746 and 0.175 – 0.337; Pb:  3.979 – 4.109, 4.144 – 4.601, 0.970 – 2.527, 2.853 – 4.367, 5.053 – 7.074 and 4.637 – 6.262 and Zn:  5.713 – 5.755, 7.956 – 8.558, 4.649 – 6.232, 5.730 – 7.745, 8.988 – 11.115 and 8.777 – 10.686 µg/g for muscle, bone, scale, intestine, gills and fins respectively. Concentrations of heavy metals in each body part of the fish were as follow: fin > gills > intestine > scale > bone > muscle for Cd; gills >  bone > fin > intestine > muscle > scale for Cu; gills > Fin > bone > intestine > muscle > scale for Pb and gills > fin > bone > intestine > scale > muscle for Zn. The concentrations of heavy metals in muscle were lower than other analyszed organs in the present study and this was considered to be an advantageous from the human health points of view as because muscle constitute the greatest mass of the fish that is consumed.

Abstract

Cumi-cumi merupakan hasil tangkapan tertinggi dari sumberdaya hayati non-ikan yang didaratkan di Pelabuhan Perikanan Nusantara Sungailiat. Selain itu cumi-cumi juga memiliki nilai ekonomis penting di Pulau Bangka, salah satunya dibuat makanan khas Bangka. Tujuan dari penelitian ini yang pertama adalah menganalisis tangkapan lestari atau maximum sustainable yield (MSY), data dianalisis menggunakan metode surplus produksi model Schaefer. Tujuan yang kedua adalah menentukan pola musim penangkapan yang dianalisis menggunakan metode rata-rata bergerak (moving average). Hasil penelitian menunjukkan bahwa: nilai parameter pendugaan yaitu cumi-cumi dengan nilai intercept (a) = 36,388 dan slope (b) = -0,00159 sehingga membentuk persamaan linier  CPUE = 36,388 – 0,00159 f. Hubungan persamaan ini dapat diartikan bahwa bila dilakukan upaya penangkapan sebesar f satuan per tahun maka akan mengurangi nilai produktivitas (CPUE) cumi-cumi sebesar 0,00159 kg/tahun.  Setelah mengetahui nilai intercept dan slope, diperoleh pendugaan nilai potensi lestari (MSY) cumi-cumi di daerah penangkapan (perairan Bangka) adalah sebesar 207.635 kg/tahun, dan pendugaan nilai upaya lestari (fMSY) adalah sebesar 11.412 trip/tahun. Berdasarkan nilai MSY dan upaya optimum tersebut, penangkapan cumi-cumi dalam kurun waktu lima tahun   (2005-2009) belum mencapai overfishing. Puncak musim penangkapan cumi-cumi terjadi di bulan November dengan nilai IMP sebesar 146,21% kemudian berturut-turut Mei (134,21%), April (119,11%), Oktober (115,83%), dan Juni (114,38%).   Kata kunci : Cumi-cumi, MSY, Musim penangkapan. ABSTRACT The squid is the highest catch of living resources of non-fish fishery landed in Sungailiat-Bangka of Archipelago Fishing Port. In addition, it also has a significant economic value on the island of Bangka, one of them is processed into typical food. The first objective of this research is to analyze the maximum sustainable yield (MSY), data were analyzed using Schaefer model. The second objective of this study is determine the pattern of the fishing season, which were analyzed using the moving average method. The result of the research indicates that the value of the parameter estimates squid with intercept value (a) = 36,388 and slope (b) = -0,00159 thus forming a linear equation CPUE = 36,388 – 0,00159 f. The relationship of this equation can be interpreted when an attempt to arrest of f units per year and reduce the value of productivity (CPUE) for squid 0,00159 kg/year. After knowing the value of intercept and slope, obtained its maximum sustainable yield value region squid waters of Bangka is 207.635 kg/year, and predicted value of optimum fishing effort (fMSY) is approximately 11.412 trip/year. Based on valuation  of the MSY and optimum fishing effort, catching squid in the last five years (2005-2009) has not reached overfishing. Peak of the squid fishing season occurs in November with a value of 146,21% IMP then successively May (134,21%), April (119,11%), October (115,83%), and June (114,38%).   Keyword : Fishing season, MSY, Squid.
