“…Biomass values account for both size and abundance of specimens (density is the most common metric in sea urchin studies, e.g., Palacín et al, 1998;Tuya et al, 2004b;Lessios, 2016), which is crucial when comparing populations that are not homogeneous in size structure, as reported for Arraial do Cabo (see Cordeiro et al, 2014). Few studies have considered the biomass of sea urchins as a variable on tropical reefs, especially in the Caribbean, despite this being the most robust metric for assessing effects of grazing (Suskiewicz and Johnson, 2017). Studies in East Africa coral reefs indicated biomass values between 50.1 to 609.5 g m −2 (Humphries et al, 2014) in areas where sea urchins showed significant control over macroalgal cover.…”

“…In their highlight article, Suskiewicz and Johnson (2017) review the scientific literature dealing with the control of feeding of the green sea urchin, Strongylocentrotus droebachiensis, and discuss the ecological implications of their findings. The phenomenon of sea urchins overgrazing marine temperate macroalgae (such as large kelp) leading to the transition of highly productive macroalgal forests into marine deserts in the form of barren urchin grounds (Fig.…”

“…In order to succeed in these "higher" goals, however, the examined laboratory-based studies and their inherent information need to be scaled up to the whole-ecosystem context, as also the authors meritoriously point out (Suskiewicz and Johnson 2017). This could be done by well-designed experiments in controlled mesocosms or in the field under natural background levels of environmental variables and natural species compositions of macroalgal assemblages coupled with realistic levels of naturally behaving sea urchins, competing herbivores and predators.…”

information of consumption rates and factors controlling the feeding of a common and widely distributed sea urchin species at higher latitudes in the northern hemisphere, the green sea urchin, Suskiewicz and Johnson (2017) deliver a vital synthesis for improved understanding of this specific phenomenon, its dynamics and mechanisms, as well as its ecological consequences.The main results from the literature review by Suskiewicz and Johnson (2017) concern factors that under laboratory conditions have been reported to control sea urchin consumption rates such as urchin size, urchin reproductive state, water temperature and algal species (food type). Although bigger urchin individuals as expected ate more than smaller individuals, the small ones consumed food at the same rates as the big ones, suggesting that simple estimations of total urchin biomass may be sufficient for the evaluation of the potential herbivore pressure in an area. A more surprising finding was that temperature did not have any clear impact on feeding rates presenting quite ambiguous results when viewed in the larger picture. The consumption of different types of macroalgae and of the same algal species during different occasions and in different regions was also puzzling at times. All algal taxa offered to the urchins were eaten and even though some species clearly were preferred above others, the actual favoured ones often differed among regions and typically ignored species could at certain places be eaten at high rates.Among the central take home messages from this review, the estimates of the maximum amounts of algae that an urchin can consume stand out explicitly as these values are quantifying key elements of the macroalgal/urchin dynamics. If consumption rates together with changes in urchin abundance are coupled with macroalgal productivity estimates of a location, ecological tipping points in the transition from macroalgal forests to barren grounds may

Telur Bulu Babi ini telah menjadi salah satu sumber daya perikanan komersial dunia (Bertocci, 2018) karena memiliki gizi yang baik dan diperdagangkan secara global.…”

Sea urchin is one of the fisheries resources products where its gonad can be consumed either in fresh or processed. Unfortunately, sea urchin has not been consumed due to society suspicion that may cause death if sea urchin gonad consumed. Thereby, we need to educate the society by instructing them in a participatory way on how to consume and cultivate sea urchin cultivation with a floating net cage. This work was conducted at Desa Lambangan Office (February 2020–March 2020) by involving 25 fishermen and 30 students from Gorontalo State University as the fellows of the society. The results of the counseling and practicing that conducted at desa Lambangan had been switched the paradigm of society that was formerly assuming sea urchin as a marine organism that has toxicity to be an organism that could be consumed and traded. Furthermore, the fishermen have overcome and able to handle how to build a floating net cage for the cultivation of sea urchins that they have learned in simulation on how to make floating net cage of sea urchins. Keywords: sea urchin; counseling; floating net cage Abstrak: Bulu Babi (sea urchin) merupakan salah satu produk perikanan penting yang telurnya dapat dikonsumsi baik dalam keadaan segar maupun olahan. Sayangnya Bulu Babi belum dimanfaatkan karena dianggap beracun dan bila dikonsumsi dapat menimbulkan kematian. Karena itu, perlu dilakukan edukasi pada masyarakat melalui kegiatan penyuluhan bagaimana cara mengonsumsi dan membudidayakan Bulu Babi dengan sistem keramba jaring apung. Kegiatan ini dilaksanakan di desa Lambangan, kecamatan Pagimana, Sulawesi Tengah selama dua bulan (Februari 2020–Maret 2020 dengan melibatkan 25 masyarakat nelayan dan 30 mahasiswa Universitas Negeri Gorontalo sebagai pendamping masyarakat. Hasil dari kegiatan penyuluhan dan simulasi yang kami laksanakan telah mengubah paradigma masyarakat yang tadinya menganggap Bulu Babi sebagai biota laut beracun menjadi sesuatu yang dapat dikonsumsi dan dapat diperjualbelikan di pasar-pasar lokal. Selain itu, masyarakat juga telah menguasai dan mampu menerapkan konstruksi keramba budi daya Bulu Babi yang dilaksanakan melalui metode praktik simulasi pembuatan keramba jaring apung.
