"Pertahanan hidup dilakukan oleh tiap organisme agar dapat terhindar dari kepunahan. Pada organisme laut, bentuk pertahanan diri ada tiga macam, dimana khususnya pada hewan dari filum Echinodermata yang menggunakan senyawa metabolit sekunder sebagai bentuk pertahanan dirinya. Tujuan dari penelitian berikut untuk mengetahui perilaku makan spesifik ikan karang terhadap pakan uji yang mengandung ekstrak Holothuria atra yang berbeda konsentrasinya telah dilakukan pada tanggal 8-14 November 2018 di Perairan Pulau Pramuka, Taman Nasional Kepulauan Seribu, DKI Jakarta. Proses yang dijalani yaitu ekstrasi menggunakan metanol dan menghasilkan persentase ekstrak kasar sebesar 0,56% dan memiliki konsentrasi fisiologis yang mengacu pada penelitian terdahulu yaitu 8 mg/mL. Proses pengujian dilakukan dengan memberikan pakan uji yang mengandung ekstrak kasar Holothuria atra yang telah dicampur oleh jeli dan pelet ikan sebanyak 4 set dengan komposisi set terdiri dari kontrol, pakan dengan ekstrak 0,5% dari konsentrasi fisiologis, pakan dengan ekstrak 1% dari konsentrasi fisiologis dan pakan dengan ekstrak 2% dari konsentrasi fisiologis. Uji perilaku makan ikan karang dilakukan di rataan terumbu karang pada tujuh titik berbeda di kedalaman 3-5 meter. Hasil uji statistik Chi-Kuadrat pada taraf signifikasi (α) 0,01 menyatakan bahwa ada perbedaan perilaku makan ikan karena perbedaan konsentrasi pakan yang digunakan dan untuk membuktikan keeratan hubungan, digunakan uji Cramer yang menunjukkan bahwa dengan nilai 0,316 dan uji ANOVA sebagai uji akhir yang pula menyatakan bahwa perilaku makan ikan karang berbeda pada masing-masing pakan yang berbeda konsentrasinya.

Life defense is carried out by each organism in order to avoid extinction. In marine organisms, there are three types of self-defense, especially in animals from phylum Echinodermata that use secondary metabolites as a form of defense.The research was purposed to know specific fish feeding behavior towards the fish food that contains different concentrations of crude extract of Holothuria atra. It was conducted on 8th until 14th November 2018 in Pramuka Island Waters, Kepulauan Seribu National Park, DKI Jakarta. The process begun with extractions of specimen using methanol to yield the 0,56% of crude extract that is equal to 8 mg/mL of physiological concentration. The fish feeding behavior assay was conducted by using artificial foods which is contained Holothuria atras crude extract mixed with jelly and fish pellets and it is made into 4 sets. Those sets composed with control, fish pellet mixed with 0,5% crude extract from physiological concentration, fish pellet mixed with 1% crude extract from physiological concentration and fish pellet mixed with 2% crude extract from physiological concentration. This field experiment conducted above the coral reefs on 7 different spots at 3-5 meter depth. Chi-square analysis (α=0,01) showed that there is difference feeding behaviour of reef fishes based on different of concentration in fish pellet. Another test used as in Cramer test to see the close relation and the result showed 0,316 and for ANOVA test showing that there is also different fish feeding behaviour as well."

ABSTRAKA research study on the impact of introduced fish has been carried out in Lake Kenanga, Agathis, Mahoni, Puspa, Ulin and Salam at The University Of Indonesia, West Java from March to April 2016. The study aims to assess the impact of introduced fishes towards the native fishes that are living in those lakes. Fish sampling was conducted through a free sampling method by using an electrofishing gear, a push net with a 2,5 cm mesh and a lift net. The results showed that there was a decline in the number of native fishes and an increase of introduced fishes which are The Red Devil (Amphilophus citrinellus) and the aligator gar (Atractosteus spatula). The red devil is a competitor for Aplocheilus panchax, Barbodes binotatus, Clarias batrachus, Oreochromis mossambicus, Oreochromis niloticus, Pterygoplichthys pardalis, Trichopodus pectoralis and Trichopsis vittata while the aligator gar is a predator that preys on all kinds of fish. Both types of fish can potentially become invasive because they have many characteristics that make them a successful invader."

A study aimed to investigate feeding behavior of reef fishes on some concentrations of Archaster typicus crude extract was conducted on 8-14 November 2018 at Pramuka Island, Kepulauan Seribu, DKI Jakarta. The concentration of Archaster typicus crude extract in artificial food is 50%, 100% and 200% physiological concentration. Observation of feeding behavior of reef fishes conducted at 3 m depth in 7 different locations. Feeding behavior calculated based on number of fish that have feeding behavior in 1-7 categories. Data analysis was done by Chi-Square statistical test, Cramer correlation test, and ANOVA test.

The result analysis of Chi-Square test, showed there are an effect by several concentrations in food artificial to reef fishes feeding behavior (P>0,01), there are the correlation between reef fishes feeding behavior and several concentrations in food artificial but the correlation is weak (C=0,389). Based on ANOVA test, extract concentration only affected to several reef fishess feeding behavior at 2,3, and 7 categories. Generally, reef fishes only tolerance to food artificial that consist <100 % physiological concentration."
