This review aims to critically analyze the source of a FPH in terms of the production process, factors affecting the quality of fish hydrolysate and the benefit to aquaculture. Both fish and fish byproducts can be used as a source for the manufacturing of FPH. The production of FPH consists of three major stages; Pre-treatment, Hydrolysis, and Recovery. Protein hydrolysis can be accomplished via biological or chemical techniques. Enzymatic hydrolysis was preferable to produce FPH in high value-added products. The recovery step mainly involves separation, concentration, and drying process. There are two ways to make FPH: liquid and dry. Dried FPH is preferred since it has a longer shelf life and is simpler to store and transport.

The results depicted highest decline in nutrients and metal concentration (40–90%) at light intensity of 40 W/m² by consortia-1 and consortia-2 treated with wastewater (50%, 100%). The result of metal remediation was further confirmed by fourier transform infrared spectroscopy (FTIR) which reflected occurrence of different functional groups in selected consortia. Moreover, light intensity of 40 W/m² induced neutral-lipid accumulation (1750 cm⁻¹) in consortia-1 as depicted in FTIR spectra. The maximum active photosystem-II reaction center (79.75%), quantum yield (26.17%) and performance index (195.8%) revealed that light intensity (40 W/m²) and wastewater augmented functioning of photosystem-II in consortia-1 than consortia-2. Further, consortia-2 appeared more sensitive to oxidative stress as the concentration of oxidative stress markers (5.73–6.39 folds) was amplified after treatment with wastewater at light intensity of 40 W/m². The prodigious tolerance potential towards different light intensities and wastewater concentration of consortia-1 may be attributed to increased activity of ascorbic acid (1.16 folds), proline (1.32 folds), cysteine (2.80 folds), superoxide dismutase (3.44 folds), catalase (2.52 folds) and glutathione reductase (1.90 folds). However, abundance of saturated fatty acid (41.34%) together with high cetane number (59.07) indicated that consortia 2 can produce excellent quality biofuel at 20 W/m² while consortia-2 at 40 W/m². Overall, consortia 1 appeared competent in terms of photosynthetic performance, remediation efficiency and antioxidant defense mechanism under 20 W/m² and 40 W/m² while consortia-2 showed quality biodiesel production at 20 W/m².
