“…Previous studies have attributed higher oyster growth rates to low-density treatments, which enhances the value of individual oysters per cultivated unit as cultivation becomes limited per area (Holliday et al, 1993;Mgaya & Mercer, 1995;Alunno-Bruscia et al, 2001;Cardoso-Junior et al, 2012;Marshall & Dunham, 2013;Azevedo et al, 2015;Roncarati et al, 2017). Additionally, overstocking situations usually drive cultivations toward a fragile state, mostly expressed in terms of increased time to marketable size and irregular growth (Beland, 1987), increased mortality, and, sometimes, individuals exhibiting morphological deformities or clumps (Galtsoff, 1964).…”

In Brazil, the cultivation of Crassostrea tulipa (= C. gasar) is gaining in importance. However, little is known about the best conditions for farming. Therefore, this study aimed to evaluate the effect of oyster density (50, 100, 200, and 400 mL of seeds/0.15 m2; 100, 200, 300, and 400 ind/0.10 m2 (basket area) and 30, 60, 120, and 180 ind/0.13 m2 (lantern floor area) in nursey, juvenile and adult phase, respectively) on the growth and survival of C. tulipa in farm cultivation. In the nursery phase, the 50 mL density resulted in smaller oyster size, as expressed in height and height/length (H/L) ratio (1.31 ± 0.03 mm), compared to other densities, while the length and width was equal among densities. The animals' individual average weight and H/L ratio were negatively influenced by a density of 100 ind/0.10 m2 or bigger. However, animals grown at the density of 200 ind/0.10 m2 did not differ statistically in length or width from those grown with 100 ind/0.10 m2. A high survival rate (≥98%) was found in the nursery and juvenile phases.

“…Success in oyster farming depends heavily on the environmental conditions of the growing area, that is the physical, chemical and biological characteristics of the environment [4,7,10,[12][13][14][15][16][17][18][19]. These factors directly influence the growth of the cultivated oyster, and because of this, several studies have been carried out [6,12,15,18,[20][21][22][23][24][25][26].…”

In the last decades the oyster faming stands out as the main mitigating measure to the decline of the fishery, as it presents socio-economic and environmental viability. However, for the success of the activity, it is necessary to understand the stages of cultivation, as well as the growth performance of the species to be cultivated. The present work aims to characterize the growth and survival of Crassostrea tulipa, cultivated on the Amazon coast. For this purpose, oysters were grouped by commercial size class (seed, juvenile, baby, average and masters) and compared the growth rates and their relationships with the abiotic variables. There was no difference in the average growth between the oyster classes, however, when comparing them in the total and percentage growth rates, a higher performance was observed in the oysters classified by juvenile and seed, respectively. The relationship of salinity to oyster growth was evidenced only in the class of juvenile oysters. The cultivation time required to obtain native oysters in the commercial size varied between four and seven months, being inferior to those found in other Brazilian regions.

ABSTRAKPengolahan air buangan tambak superintensif (TSI) adalah usaha untuk mengurangi beban bahan pencemar yang terkandung di dalam air buangan TSI sehingga aman dan tidak membahayakan saat dibuang ke lingkungan. Penelitian ini bertujuan untuk mengevaluasi desain dan performansi Instalasi Pengolahan Air Limbah (IPAL) dalam memperbaiki kualitas air buangan TSI sebelum dibuang ke badan air. IPAL terdiri atas kolam sedimentasi, dua kolam aerasi, dan satu kolam penampungan. Ke dalam kolam penampungan ditebari ikan mujair serta rumput laut Gracilaria sp. yang dibudidayakan dengan metode long line, berfungsi sebagai biokontrol. Sampel air diambil di bagian inlet IPAL, oulet kolam sedimentasi atau inlet kolam aerasi-1, outlet kolam aerasi-1 atau inlet kolam aerasi-2, outlet kolam aerasi-2 atau inlet kolam penampungan, serta outlet kolam penampungan, setiap dua minggu selama 105 hari pemeliharaan. Parameter yang diukur adalah total padatan tersuspensi (TSS), total amonia nitrogen (TAN), nitrit, nitrat, fosfat, bahan organik terlarut (BOT), dan biological oxygen demand
