| Abstract: | Perairan Palabuhanratu dan Blanakan di selatan dan utara Pulau Jawa
memiliki potensi perikanan cukup besar dan berperan penting dalam produksi
perikanan nasional. Cumi-cumi menjadi salah satu komoditas perikanan di perairan
Palabuhanratu dan Blanakan. Permintaan pasar yang tinggi menyebabkan tingginya
tekanan penangkapan cumi-cumi yang berdampak pada ketidakseimbangan
ekosistem di perairan utara dan selatan Jawa. Penelitian ini bertujuan untuk
menganalisis komposisi makanan dan relung trofik cumi-cumi Uroteuthis spp. dan
Sthenoteuthis sp. di perairan Teluk Palabuhanratu dan Blanakan. Cumi-cumi
ditangkap menggunakan waring, pukat cincin dan pancing tonda pada kurun waktu
Mei-September 2022. Analisis data meliputi diameter mata relatif, indeks bagian
terbesar, luas relung makanan, tumpang tindih relung makanan, dan tingkat trofik.
Hasil penelitian menunjukkan bahwa komposisi makanan Uroteuthis spp. terdiri
atas potongan ikan, krustasea, moluska, annelida, dan makanan yang tidak
teridentifikasi; sedangkan makanan Sthenoteuthis sp. terdiri atas potongan
krustasea, ikan, dan moluska. Makanan utama cumi-cumi Uroteuthis spp. dan
Sthenoteuthis sp. adalah ikan dan krustasea. Cumi-cumi di perairan Teluk
Palabuhanratu dan Blanakan memiliki peran sebagai hewan karnivora dan
menempati posisi tingkat trofik IV dalam jejaring makanan di perairan. The Palabuhanratu and Blanakan waters in the south and north of Java Island have considerable fisheries potential and play an important role in national fisheries production. Squid is one of the fishery commodities in Palabuhanratu and Blanakan waters. High market demand has led to high squid fishing pressure which has an impact on ecosystem imbalance in the waters of north and south of Java Island. This study aims to analyze the food composition and trophic niche of Uroteuthis spp. and Sthenoteuthis sp. squid in the waters of Palabuhanratu Bay and Blanakan. Squid were caught using waring, purse seine, and tonda fishing rod during MaySeptember 2022. Data analysis included relative eye diameter, largest part index, food niche area, food niche overlap, and trophic level. The results show that diet composition of Uroteuthis spp. consisted of pieces of fish, crustaceans, mollusks, annelids, and unidentified food; while the diet of Sthenoteuthis sp. consisted of pieces of crustaceans, fish, and mollusks. The main food of Uroteuthis spp. and Sthenoteuthis sp. squid are fish and crustaceans. Squid in the waters of Palabuhanratu Bay and Blanakan play a role as carnivorous animals and occupy the position of trophic level IV in the marine food web. |
