Aditya Rizqi Agung, 260 401 171 301 07. Identifikasi Jenis Udang Tangkapan
Nelayan di Perairan Desa Menco, Kecamatan Wedung, Kabupaten Demak (Nur
Tufiq-Spj dan Ria Azizah).
Udang merupakan salah satu hasil perikanan unggulan di Indonesia.
Perairan Utara Jawa khusunya di Kabupaten Demak merupakan salah satu wilayah
penghasil komoditas ikan di Jawa Tengah. Namun, besarnya potensi perikanan
udang juga diiringi dengan tekanan alam dan antropogenik yang besar, khususnya
di Perairan Utara Jawa. Perlu adanya pemantauan terhadap ketersediaan jenis
udang untuk menjaga kelimpahan jenis udang di alam liar. Penelitian ini bertujuan
untuk mengetahui jenis udang tangkapan nelayan di Perairan Desa Menco,
Kecamatan Wedung, Kabupaten Demak. Penelitian ini dilakukan pada Bulan
November - Desember 2021. Pengambilan sampel udang dilakukan dengan metode
purposive sampling. Sampel udang diperoleh dari hasil tangkapan 3 orang nelayan
di Desa Menco. Dilakukan pengukuran karakter morfometrik dan meristik untuk
membedakan tiap sampel udang. Sampel udang diidentifikasi sesuai dengan ciri -
ciri fisiologis berdasarkan buku panduan identifikasi. Pengukuran morfometrik dan
meristik dilakukan dengan mengukur 19 karakter meliputi: panjang karapas,
panjang ruas pertama, panjang ruas kedua, panjang ruas ketiga, panjang ruas
keempat, panjang ruas kelima, panjang ruas keenam, kedalaman ruas keenam,
panjang total, panjang badan, prosartema, panjang antenna, panjang anntenule,
exopod, endopod, telson, jumlah gigi pada rostum, jumlah kaki renang, dan jumlah
kaki jalan. Hasil penelitian menunjukkan bahwa terdapat 6 jenis udang yang
tertangkap oleh nelayan di perairan Desa Menco, Kecamatan Wedung, Kabupaten
Demak. Keenam jenis udang tersebut adalah Udang Putih (Penaeus merguiensis),
Udang Tenger (Metapenaeus ensis), Udang Windu (Penaeus monodon), Udang
Buku (Macrobrachium equidens) dan Udang Ronggeng. Terdapat 2 jenis Udang
Ronggeng yang ditemukan yaitu Oratosquilla oratoria dan Harpiosquilla
raphidea. Dari hasil tersebut, diketauhi bahwa perairan Desa Menco merupakan
estuari yang menjadi habitat yang sesuai bagi jenis-jenis udang tersebut.

SUMMARY

Aditya Rizqi Agung, 260 401 171 301 07. Identification of Shrimp Catch by
Fishermen in the Waters Around Menco Village, Wedung District, Demak Regency
(Nur Tufiq-Spj dan Ria Azizah).
Shrimp is one of the dominant fishery products in Indonesia. The Northern
Coast of Java, especially in Demak Regency, are one of the leading shrimpproducing areas in Central Java. However, the large potential of shrimp fisheries
is also accompanied by great pressures (natural and anthropogenic). It is
necessary to monitor the availability of shrimp species to maintain the abundance
of shrimp species in the wild. This study aims to determine the types of shrimps
caught by fishermen around the waters of Menco Village, Wedung District, Demak
Regency. This research was conducted in November - December 2021. Sampling
of shrimp was carried out using purposive sampling method. Shrimp samples were
obtained using trap net ini Menco Village. Measurement of morphometric and
meristik characters was carried out to distinguish each shrimp sample. Shrimp
samples were identified according to the physiological characteristiks based on the
identification guidebook. Morphometric and meristik measurements were carried
out by measuring 19 characters including: carapace length, first segment length,
second segment length, third segment length, fourth segment length, fifth segment
length, sixth segment length, sixth segment depth, total length, body length,
prosartema, antenna length, anntenule length, exopod, endopod, telson, number of
teeth on rostum, number of swimming legs, and number of walking legs. The results
showed that there were 6 types of shrimp caught by fishermen in the waters of
Menco Village, Wedung District, Demak Regency. The six types of shrimps are
White Shrimp (Penaeus merguiensis), Tenger Shrimp (Metapenaeus ensis), Windu
Shrimp (Penaeus monodon), Buku Shrimp (Macrobrachium equidens) and
Ronggeng Shrimp. There were 2 different species of Ronggegn Shrimps namely
Oratosquilla oratoria and Harpiosquilla raphidea. From these results, it is known
that the waters of Menco Village are estuaries which are suitable habitats for
thesetypes of shrimp.
