Abstract. Yusup DS, Mahardika IG, Suarna IW, Giri INA. 2020. Feeding preference and growth response of early adults abalone, Haliotis squamata on some macroalgae. Biodiversitas 21: 4369-4375. Study on early adult Haliotis squamata fresh feed has evaluated some macroalgae, however, a study on Enteromorpha sp., Halymenia sp., and Hypnea sp. have not been carried out. This study was proposed to evaluate the feeding preference (feed response and feed intake) and the growth performance of early adult H. squamata on some macroalgae. Seven species of macroalgae were evaluated as unpair feeding choice and the experiment design employed was completely randomized design. The results showed that H. squamata responded variously to the seven macroalgae species and the food deprivation (fasting) data showed mounting response to all macroalgae. Ulva lactuca and Enteromorpha sp. were the most responded which up to four times higher compared to the least responded i.e. Halymenia sp. and Sargassum sp. The highest to the lowest palatable feed intake (FI) were Gracillaria sp, Eucheuma spinosum, Ulva lactuca, Halymenia sp., Enteromorpha sp., Sargassum sp. and Hypnea sp. respectively. The first four palatable macroalgae resulted in various growth responses of H. squamata. Except for Halymenia sp., the feed intake (FI) rate showed an opposite linear correlation to growth response and FCR. The daily growth rate (g/day) was Ulva lactuca (0.104), Enteropmorpha sp. (0.085), Gracillaria sp. (0.084), and Halymenia sp. (0.016).

Ikan nila merupakan salah satu dari jenis ikan air tawar yang memiliki nilai ekonomis tinggi. Salah satu yang menjadi permasalahan dalam kegiatan budidaya adalah harga bahan baku pakan yang relatif mahal. Untuk mengatasi hal tersebut, penggunaan tepung rumput laut dapat menjadi salah satu bahan alternatif dalam mengurangi pengunaan tepung ikan dan tepung kedelai pada pakan. Tujuan penelitian ini adalah menganalisa pengaruh penambahan tepung rumput laut E. cottonii pada pakan terhadap pertumbuhan dan kelangsungan hidup ikan nila (O. niloticus). Metode penelitian yang digunakan adalah metode eksperimen dengan menggunakan rancangan acak lengkap (RAL), dengan 4 perlakuan dan 3 ulangan. Perlakuan dalam penelitian ini yaitu P1 (kontrol/ tanpa tepung rumput laut), P2 (tepung E. cottonii 4%), P3 (tepung E. cottonii 8%), P4 (tepung E. cottonii 12%). Data dianalisis menggunakan analisa sidik ragam (ANOVA) dengan taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa penambahan tepung rumput laut E. cottonii pada pakan memberikan pengaruh yang signifikan terhadap pertumbuhan berat mutlak dan pertumbuhan panjang mutlak pada ikan nila, akan tetapi tidak memberikan pengaruh yang signifikan terhadap laju pertumbuhan spesifik, efesiensi pemanfaatan pakan, rasio konversi pakan dan kelangsungan hidup ikan nila.

“…To test whether food consumption is a function of temperature (Experiment 1), we produced agar-pellets containing Ulva lactuca powder (Xi'an XiaoCao Botanical Development Co., Ltd, China). Ulva lactuca is commonly used as food for abalone in hatcheries and is known to be consumed by H. squamata (Giri et al 2016;Heru Prihadi et al 2018;Yusup et al 2020). For the pellets, we mixed 7.2 g of agar powder with 100 mL of distilled water and boiled the mixture for 5 s in a microwave (800 watts).…”

Exposure to moderately elevated temperatures changes food preferences in the tropical marine herbivore Haliotis squamata

et al. 2021

Ocean warming is affecting marine ectothermic herbivores as well as the macroalgal species they consume and this has the potential to alter their trophic interaction. However, it is currently still unknown how these two important components of benthic food webs will react to a warming environment. Consumption rates of grazers change with increasing temperatures, but it is unclear whether this is also true for feeding preferences. In this study, multiple-choice feeding assays with the tropical abalone Haliotis squamata from Western Indonesia were conducted in August 2018. After brief acclimation of either the grazer or the macroalgae to moderately elevated water temperatures (maximum 2 °C above the long-term average) in the laboratory, three species of living macroalgae were simultaneously offered to the abalone in feeding assays. Consumption rates of H. squamata were lower under elevated water temperatures, while its feeding preference switched: At 27 °C (2 °C below long-term average), abalone preferred non-acclimated Gracilaria salicornia, but switched to non-acclimated Amphiroa spp. at 31 °C. Interestingly, no such switch in preference occurred when the macroalgae, but not the grazers were acclimated. This indicates that the grazer will presumably be the driver of this potential change in interactions between H. squamata and its macroalgal food. Ocean warming may result in changes in the structure of benthic communities, mediated by changes in the feeding behaviour of herbivorous invertebrates.
