“…The experiment was run in the same recirculating aquaculture system (RAS) made up of 40 L aquaria each connected in tandem (Grosso et al, 2021). This RAS was specifically designed for feeding investigations, as it was equipped with an efficient waste removal system.…”

“…Carrots, maize and soy were employed to make up the vegetable base of all the experimental diets. In each diet, 119.80 g (carrots), 33.73 g (maize) and 46.46 g (soy) respectively, were used to obtain the same proportion (1: 1: 1) of vegetables in dry weight (Table 2) (Grosso et al, 2021). The vegetables were steamed, blended and extruded with different levels of fish-meal enrichment (0%, 20% and 40%) using agar-agar (Nature et Plantes -St Paul Les Dax, France) as a binder to minimize food dispersion Volpe et al, 2018).…”

Investigations on trophic requirements of different life cycle stages of Paracentrotus lividus are crucial for the comprehension of species ecology and for its artificial rearing. The future success of echinoculture depends heavily on the development of suitable and cost-effective diets that are specifically designed to maximize somatic growth during the early life stages and gonadal production in the later stages. In this context, a considerable number of studies have recommended animal sources as supplements in sea urchin diets. However, with the exception of Fernandez and Boudouresque (2000), no studies have investigated the dietary requirements over the different life stages of the sea urchin. In the present study, the growth and nutrition of three life stages of P. lividus (juveniles: 15-25 mm; subadults: 25-35 mm; adults: 45-55 mm) were analyzed over a 4-month rearing experiment. Three experimental diets, with 0%, 20% and 40% of animal sourced enrichments, were tested in parallel in sea urchin three size classes. The food conversion ratio, somatic and gonadal growth were assessed in each condition in order to evaluate the optimal level of animal-sourced supplements for each life stage. A general growth model covering the full post-metamorphic P. lividus life cycle was defined for each condition. During the juvenile stage P. lividus requires higher animal supply (40%), while a feeding requirement shift takes place toward lower animal supply (20%) in sub-adult and adult stages. Our results evidenced that the progressive increase in size after the metamorphosis led to a consequent variation of trophic requirements and food energy allocation in the sea urchin P. lividus. Macronutrient requirements varied widely during the different life stages, in response to changes in the energy allocation from somatic growth to reproductive investment. This study sheds light on P. lividus trophic ecology, broadening our basic knowledge of the dietary requirements of juveniles, sub-adults and adults as a function of their behavior also in the natural environment.

“…Algaculture is the form of aquaculture that produces algae in a controlled temperature, source of light and dietary properties (Lucas et al, 2019). The integrated multitrophic aquaculture (IMTA) is an evolved aquaculture system which combines different species with distinct nutritional needs into one framework (Grosso et al, 2021). An example of this method is growing seaweed which utilises ammonia and phosphorus excreted by fish and shrimp while oyster fish feed on the solids produced by fish and shrimps.…”

The aquaculture industry in the Middle East (ME) is still relatively new compared to other parts of the world, making this region highly dependent on other countries for the production of food and feed needs. Aquaculture activities in the world at current is mainly focused in China; this may be propelled by its own internal demand for seafood as determined by the United Nations Food and Agriculture Organization (FAO). Challenges faced in the ME has not been elucidated so far and the issues arising might be unique only to this region due to aquaculture being in the initial stages coupled with water access and limitations, climate and geography, in addition to pollution. This review paper will present and discuss global needs for seafood focusing later on the needs in the ME, followed by a discourse into the importance, types and challenges of aquaculture in the ME. Baseline knowledge and infrastructure to enhance knowledge is a pressing need at this stage of infancy. It is hope this sector will continue to develop, and with the support of stakeholders, aquaculture in the ME will achieve a state of independence.

“…Penggunaan bulu babi dan teripang sebagai komoditas ekstraktif IMTA juga cukup efektif memanfaatkan energi dan nutrisi dari komoditas utama (Israel et al 2019). Dua komoditas tersebut juga terbukti sebagai suatu IMTA yang efektif, dengan bulu babi sebagai komoditas utamanya (Grosso et al 2021).…”

“…IMTA dan RIMTA salah satu cara untuk memitigasi pelepasan limbah budidaya, mengurangi jejak ekologi (ecological footprint), diversifikasi nilai ekonomi dan meningkatkan keberterimaan sosial sistem budidaya ikan (Troell et al 2009), mengontrol biofouling (Sterling et al 2016) dan pengelolaan endapan (Shpigel et al 2016) di perairan lokasi budidaya, serta sebagai cara biomitigasi limbah budidaya dan mengurangi serangan penyakit (Granada et al 2018). Dengan model IMTA dan RIMTA, penerapan pendekatan remediasi berpotensi memberikan tambahan penerimaan (revenue) dari nilai hasil panen komoditas ekstraktif (Grosso et al 2021). Disamping itu, dari perspektif sosial terdapat nilai manfaat jasa lingkungan (environmental services) dari komoditas ekstraktif yang dapat divaluasi menggunakan pendekatan ekonomi lingkungan.…”

Untuk mengoptimalkan manfaat ekonomi keberadaan sumberdaya benih lobster di perairan Indonesia, maka pengembangan budidaya lobster oleh pembudidaya dan pelaku usaha dalam negeri perlu segera dilakukan. Mempertimbangkan perkembangan adopsi teknologi budidaya lobster saat ini, maka segmen usaha pendederan perlu dilaksanakan pada fasilitas unit pelaksana teknis (UPT) Direktorat Jenderal Perikanan Budidaya, segmen usaha selanjutnya yaitu pembesaran lobster di Karamba Jaring Apung (KJA) laut dapat melibatkan masyarakat/ pembudidaya dan pelaku usaha. Implementasi Integrated Multi Tropic Aquaculture (IMTA) pada budidaya lobster baik pada skala unit maupun kawasan dapat mewujudkan prinsip keberlanjutan, mengoptimalkan pemanfaatan sumberdaya, meningkatkan penerimaan pembudidaya dan pelibatan masyarakat lebih banyak, menyediakan jasa lingkungan (environmental service) dari komoditas ekstraktif serta sekaligus sebagai kontribusi perikanan budidaya dalam mitigasi emisi gas rumah kaca. Beberapa komoditas ekstraktif yang berpotensi dibudidayakan bersama lobster adalah rumput laut, kekerangan, teripang dan beberapa jenis ikan bertropik level rendah. Dibutuhkan penelitian terkait pakan yang efektif untuk benih dan pembesaran serta manajemennya, parameter lingkungan yang optimal, metode budidaya, jenis hama dan penyakit lobster serta penanggulangannya.
