Gracilaria verrucosa as biofilter can absorb and utilize inorganic nitrogen and phosphorus contained in pollutants for its growth. This research aims to know the ability of G. verrucosa as shrimp pond waste biofilter, to know the difference in the quality of shrimp pond wastewater before and after treatment, and to learn more about the absorption capacity of G. verrucosa capability against shrimp pond wastewater. The experiment was conducted on a laboratory scale using a Completely Randomized Design (CRD) consisting of four treatments with three replications using G. verrucosa of different weights which were 100 g, 150 g, 200 g, and controls. The parameters observed in the study were water quality parameters, seaweed biomass, and seaweed absorption. The results obtained were temperature 27.2-30.1°C, TSS 7-76 mg.L -1 , pH 7.42-8.83, salinity 16-18 ppt, DO 1.7-5.3 mg.L -1 , biomass 74-210.7 g, ammonia effectively decreased on 10 th day by 90%, nitrate on 20 th day was 22.2% and phosphate value on 30 th day was 20.1%. G. verrucosa absorbed nitrogen (N) 0.08% and phosphorus (P) 0.35%. G. verrucosa is potential as a biofilter and can be used as a species candidate for IMTA system.

“…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).…”

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.

“…A viable strategy to reduce and reuse the discharge of nutrients from the Pacific white shrimp crop is by a polyculture practice through integrated multitrophic aquaculture (IMTA). IMTA can reduce the environmental impact of cultivated species since their wastes are re-utilized as input for another species (Chopin et al 2001, Ridler et al 2007, Estim 2015, Granada et al 2018. IMTA creates a balanced system that benefits environments as a result of processes such as bioremediation (Barrington et al 2009, FAO 2009) and combine economic viability (i.e.…”

A feeding trial was carried out to evaluate the utilization of residual nutrients from shrimp farming wastes (SFW) as co-feed in juvenile grey mullets Mugil cephalus. Four treatments were designed to offer shrimp farming wastes in different proportions as feed. The first treatment (control) consisted of feeding the entire daily portion with only commercial feed for marine fish (SFW0). The remaining treatments replaced the daily feed with shrimp farming wastes in 33, 66, and 100%, respectively, treatments SWF33, SWF67, and SWF100. Feed was offered daily as 4% of the grey mullet total biomass at each experimental tank. Results showed that final weight, weight gain, specific growth rate, relative weight gain, and thermal growth coefficient were reduced in the fish when the proportion of SFW in their feed was increased. However, the fish showed a digestive capacity that allowed them to use residual nutrients in a ratio up to 66%, increasing their initial weight by up to 25%. The increase of shrimp farming waste as feed negatively affected the whole-body proximal composition. The digestibility results showed that the fish could digest up to 41% of the shrimp farming waste protein. Results suggest that juvenile grey mullets are capable of utilizing residual nutrients from shrimp farming waste. However, it is necessary to complement an alternative feed source to induce an optimal growth performance for the juvenile grey mullets. It is also recommended that mullets be fed with formulated feed to meet their nutritional requirements to maintain the protein and lipid content of the whole body under culture conditions.
