Ikan di Kawasan Perairan Pantai Mangkang Wetan Kecamatan TuguKota
Semarang(Anhar Solichin danMax Rudolf Muskananfola).
Juvenil ikan termasuk fase kehidupan awal dari pertumbuhan ikan, dimana
perkembangan organ tubuh belumterbentuk secara sempurna. Distribusi dan
kelimpahan juvenil ikan bergantung pada kondisi perairan di dalamnya. Perairan
Pantai Mangkang Wetan merupakan perairan yang terhubung langsung ke laut dan
dipengaruhi oleh aktivitas daratan serta memiliki ekosistem mangrove. Penelitian
ini bertujuan untuk mengetahui komposisi dan kelimpahan juvenil ikan serta
hubungannya dengan pasang surut di kawasan PerairanPantai Mangkang Wetan..
Penelitian dilaksanakan pada bulan Agustus-September 2019. Metode penelitian
yang digunakan adalah metode studi kasus. Juvenil ikan yang berhasil
teridentifikasi terdiri dari 14 famili, yang terdiri dari famili Carangidae,
Engraulidae, Kuhliidae, Mugilidae, Gobiidae, Leiognathidae, Terapontidae,
Platycephalidae, Chanidae, Triacanthidae, Scianidae, Sphyranidae, Sillaginidae,
dan Siganidae. Juvenil ikan Mugilidae tertangkap paling banyak dari total
pengambilan sampel yaitu 597 individu, sedangkan juvenil ikan yang tertangkap
paling sedikit dari total pengambilan sampel adalahTerapontidae, Triacanthidae,
dan Sillaginidae yaitu masing – masing 1 individu.Rata – rata kelimpahan juvenil
ikan pada saat pasang adalah 145 ind/375m

,sedangkan rata – rata kelimpahan
juvenil ikan pada saat surut adalah 221 ind/375m

.Nilai perhitungan nilai signifikan
(Sig.) analisa pengaruh pasang surut terhadap kelimpahan juvenil ikan diperoleh
0,047. Nilai Sig. tersebutlebih kecil dibandingkan nilai α (0,05), sehingga dapat
disimpulkan bahwa pasang surut memiliki pengaruh terhadap kelimpahan juvenil
ikan pada lokasi penelitian.

ABSTRACT
Christian Delahoya. 26010115120034. Distribution and Abundance of Fish
Juvenile inMangkang Wetan Coastal Water, Tugu District, Semarang
City.(Anhar Solichin and Max Rudolf Muskananfola).
Fish juvenile is an early life phase of fish growth in which the
development of the organs has not yet been fully formed. The distribution and
abundance of juvenile fish are highly dependent on the water conditions. Mangkang
Wetan Coastal Water is a coastal area directly connected to the sea and influenced
by land activities also having a mangrove ecosystem in it. This study aims to
determine the composition and abundance of juvenilefish and their relationship
with the tides in Mangkang Wetan Coastal Water. Theresearch was conducted in
August-September 2019. This research used the case study method to determine the
sampling sites. The identified fish juveniles are consist of 14 families: Carangidae,
Engraulidae, Kuhilidae, Mugilidae, Gobiidae, Leiognathidae, Terapontidae,
Platycephalidae, Chanidae, Triacanthidae, Scianidae, Sphyranidae, Sillaginidae,
and Siganidae. Mugilidae fish juveniles are the most caught in this research (597
individuals). Meanwhile, Terapontidae, Triacanthidae, and Sillaginidae fish
juvenile are the least caught because only one individual for each family was
caught. The fish juveniles average abundance at thehigh tide is 145 ind/375m
3
and
221 ind/375m
3
at the low tide. Significant analysis result (Sig.)of tidal influence on
juvenile fish abundance is 0.047. It means that thesignificant value < α value (0,05),
so it can be said that the tides influence the abundance of juvenile fish at the study
location.
