Mudskipper merupakan ikan dari family Gobiidae: subfamili Oxudercinae. ikan
Mudskipper termasuk kedalam kelompok ikan penetap sejati di kawasan mangrove,
dimana pada ekosistem mangrove terdapat berbagai sumber makanan yang menjadi
nutrisi bagi ikan mudskipper. Informasi mengenai kebiasaan makan dari ikan ini sangat
dibutuhkan agar dapat di lakukan upaya domestikasi untuk menjaga kelestarian ikan
mudskipper. Penelitian ini bertujuan untuk menganalisis kebiasaan makan ikan
musdkipper pada ekosistem mangrove di pesisir Utara Aceh. Penelitian ini dilakukan
pada bulan Mei-Juni 2024 bertempat pada ekosistem mangrove di pesisir Utara Aceh.
Pengambilan sampel ikan sebanyak 80 individu pada 4 lokasi yang berbeda yaitu,
Ruyung, Alue Naga, Lambadeuk dan Kampung Jawa dengan menggunakan metode
purposive sampling. Sampel penelitian yang diperoleh dari lapangan kemudian
diambil bagian lambung serta ususnya dan diawetkan menggunakan larutan formalin
4%, jenis makanan dianalisis menggunakan mikroskop digital di Laboratorium Biologi
Laut, Fakultas Kelautan dan Perikanan, Universitas Syiah Kuala. Parameter kualitas
perairan yang diukur meliputi suhu, salinitas, pH air, DO dan substrat. Parameter yang
dihitung, terdiri Index of Preponderance, presentase volume, frekuensi kejadian,
penentuan luas relung dan panjang usus relatif. Hasil penelitian diperoleh 6 kelompok
besar makanan yaitu Fitoplankton, Nematoda, Crustacea, Polychaeta, Hexapoda dan
pecahan detritus. Nilai indeks bagian terbesar menunjukkan bahwa nematoda
merupakan makanan utama ikan mudskipper yang memiliki nilai IP sebesar 47%.
Sehingga dapat disimpulkan bahwa ikan mudskipper bersifat karnivora.

Mudskipper is a fish from the Gobiidae family: Oxudercinae subfamily. Mudskipper fish are included in the group of true resident fish in the mangrove area, where in the mangrove ecosystem there are various food sources that provide nutrition for mudskipper fish. Information about the eating habits of this fish is needed so that domestication efforts can be carried out to maintain the sustainability of mudskipper fish. This study aims to analyze the eating habits of musdskipper fish in the mangrove ecosystem on the North coast of Aceh. This study was conducted in May- June 2024 in the mangrove ecosystem on the North coast of Aceh. Fish samples were taken as many as 80 individuals at 4 different locations, namely, Ruyung, Alue Naga, Lambadeuk and Kampung Jawa using the purposive sampling method. The research samples obtained from the field were then taken from the stomach and intestines and preserved using 4% formalin solution, the type of food was analyzed using a digital microscope at the Marine Biology Laboratory, Faculty of Marine Affairs and Fisheries, Syiah Kuala University. The water quality parameters measured included temperature, salinity, water pH, DO and substrate. The parameters calculated consist of Index of Preponderance, volume percentage, frequency of occurrence, determination of niche area and relative intestinal length. The results of the study obtained 6 large food groups, namely Phytoplankton, Nematoda, Crustacea, Polychaeta, Hexapoda and detritus fragments. The largest index value shows that nematodes are the main food of mudskipper fish which have an IP value of 47%. So it can be concluded that mudskipper fish are carnivorous.
