Distribution of anchovy length size using puring net in Pulolampes Waters, Brebes Regency of Central Java

Abstract

Ikan Teri (Stolephorus sp.) merupakan komoditas bernilai ekonomi di Pulolampes-Brebes umumnya ditangkap dengan jaring puring yang berbahan utama waring. Distribusi ukuran ikan teri berguna untuk mengetahui sebaran ukuran ikan teri dan informasi tentang stok, serta sebagai data dasar upaya pengelolaan dan pemanfaatan ikan teri. Penelitian ini bertujuan menganalisa komposisi ikan hasil tangkapan untuk mendapatkan keragaan struktur hasil tangkapan dan ukuran serta pola pertumbuhan ikan teri hasil tangkapan jaring puring. Lokasi pengamatan di sentra perikanan tangkap yaitu Tempat Pelelangan Ikan (TPI) Pulolampes. Waktu pengamatan pada bulan Maret-April dan Juli-Agustus tahun 2017. Metode pengamatan dilakukan dengan pengamatan selama operasi penangkapan (experimental fishing), pengambilan data secara purposive sampling. Pengukuran dan analisa menggunakan program SPR. Berdasarkan data hasil pengamatan diperoleh ikan teri yang terpanjang adalah 91 cm, dengan beratnya adalah 6,5 g, sedangkan ukuran yang terpendek adalah 29,8 mm, dengan beratnya adalah 2 gram dan modus ukuran 62,9 mm. Penangkapan ikan teri pada bulan Agustus 2017 lebih layak tangkap dibandingkan pada bulan April dan Mei 2017. Hasil perhitungan panjang dan berat tubuh ikan dengan menggunakan rumus maka diperoleh hasil di lokasi Perairan Pulolampes diperoleh b = 1,041. Dari hasil perhitungan menunjukan nilai b berada dibawah 3 menunjukkan pola pertumbuhan ikan teri di Perairan Pulolampes, Brebes bersifat allometrik negatif. berdasarkan pertumbuhan ikan teri yang bernilai allometrik negatif, menunjukkan pertumbuhan panjang tubuh lebih dominan dibanding pertambahan bobot. Keadaan ini mengindikasikan bahwa kondisi lingkungan Perairan Pulolampes Brebes cocok untuk pertumbuhan ikan teri dan masih aman dari tekanan aktivitas penangkapan.

Age and Growth of Japanese Anchovy (Engraulis japonicus, Temminck & Schlegel, 1846) in Coastal Waters around Shandong Peninsula, China

“…Conversely, autumn and winter exhibit a significant prevalence of smaller-sized anchovies, particularly noticeable during autumn, with sizes ranging from 30 to 50 mm. This suggests recruitment events occurring within the existing population [63,64]. The size dominance observed in each season aligns with Zhu et al [27], who found that larger anchovies were more common in spring, whereas sizes ranging from 20 to 70 mm were dominant in winter.…”

Sail technology on fishing vessel for blue swimming crab catching application - A review

“…With the advancement of technology in the capture fisheries sub-sector, including boats, fishing gear, and deck machinery, a fisherman will most likely consider employing technology that is more ecologically friendly from an economic standpoint. Like the puring net fishermen in Pulolampes, the 'ciker net' in Teluk Penyu, then the 'cantrang' on the north coast of Java [21,22,23], and the BSC fisherman in Rembang, they are basically aware that the use of eco-friendly and economical technology will be very helpful them in carrying out fishing activities, but again problems will always arise, both technical and non-technical which makes them return to old habits that tend to be inefficient and not environmentally friendly. Especially lately, the increase in fuel oil is felt by fishermen so they choose not to go to sea because the results obtained are not proportional to the capital spent.…”

Conditions and Types of Anchovies in the Coastal Waters of the Spelman Strait, Central Buton Regency, Indonesia

“…The purpose of this anchovy fishery research is to classify the forms, parameters of the waters and to estimate the characteristics of the habitat. Research on anchovy fisheries has been performed by previous researchers both domestically and internationally, such as in the waters of the Gulf of Palabuhanratu (Utami et al 2018), the coastal waters of Tegal (Sutono & Susanto 2016), the waters of Pulolampes, Central Java (Sasmita et al 2018), the coastal waters of Spermonde Pangkep (Safruddin et al 2014), the waters of the Gulf of Bone (Safruddin et al 2018). In the waters of the deep Ambon Bay (Ongkers 2008), in the South Andaman waters (Kumar et al 2015), in the waters of the Mediterranean Sea (Giannoulaki et al 2012).…”
