Farfantepenaeus paulensis juveniles (72 ± 24 mg), were reared in a suspended microbial flocs system and fed practical diets containing increasing amounts of crude protein (250, 300, 350, 400 and 450 g kg−1 CP). Development of microbial flocs was promoted by high aeration rates and fertilization with wheat bran and molasses. Flocs were composed of detritus in the form of flocculated matter colonized by heterotrophic bacteria, cocoid and filamentous cyanobacteria, flagellate and ciliate protozoa and rotifers. Proximate composition analysis of the suspended microbial floc showed CP levels of 304 g kg−1. After 45 days, mean shrimp survival were above 89%, with no significant differences between treatments. Shrimp fed diets with 350 g kg−1 or higher CP content achieved significant higher (P < 0.05) final weight (0.66–0.68 g), weight gain (0.58–0.61 g) and instantaneous growth rate (0.049–0.050), with feed conversion rates (2.17–2.30) significantly lower (P < 0.05). Results show that, when rearing is carried out in a suspended microbial flocs system, dietary CP levels can be kept at 350 g kg−1. Furthermore, results confirm that microbial‐based systems allow shrimp culture without compromising the surrounding environment and shows the possible reduction of production costs and fish meal dependence.

The nutritional quality of biofilm, a microbial community associated to an organic matrix, was evaluated in artificial substrate (polyethylene screen) in net cages during 30 days in the Patos Lagoon estuary, Southern Brazil. During this period, samples of biofilm were collected each 5 days for analysis of chlorophyll a, microorganisms abundance, dry weight, protein and lipid contents. During the study, chlorophyll a varied from 0.38 to 2.75 lg cm )2 ; dry weight between 7.16 and 17.63 mg cm )2 ; protein content from 0.43 to 1.76 mg cm )2 and lipid concentration between 1.21 and 4.23 mg cm )2 . The variation of lipid in the biofilm was closely related to the abundance of free heterotrophic bacteria (34.25-56.54 · 10 6 cells cm )2 ), filamentous cyanobacteria (7.5-15.9 · 10 6 filaments cm )2 ), flagellates (6.92-12.89 · 10 6 cells cm )2 ) and mainly nematodes (29-1,414 organisms cm )2 ), while protein content varied similarly to the abundance of unicellular centric diatoms (52.10-179.81 · 10 3 cells cm )2 ), and nematodes. This information will allow a better management of food supply to raised aquatic organism with the utilization of natural productivity in the culture systems, with considerable decrease in production costs.

“…According to [28], fish meal combined with several types of marine invertebrates (squid and shellfish) as raw material for feed resulted in better fish growth than fish fed with fish meal alone. This is because feeds sourced from several different protein sources can complement each other to have a more balanced nutrient composition than feeds from only one protein source.…”

Increasing the target of aquaculture production will increase the need for feed which an increase will follow in the need for fish meal. The constraint in aquaculture fish feed dependence on a fish meal import is known. In efforts to find local raw materials to reduce dependence on fish meals, one source of quality animal protein from marine resources as raw material for feed that needs to be studied and developed is mollusks or mussels. This review summarizes the use of mussel meal in aquaculture feed and is expected to provide a comprehensive overview of the existing studies’ potential on mussels meal used as a feed ingredient in fish feed. Many species of mussel have been tested for raw material in fish feed such as blue mussel (Mytilus galloprovincialis), Freshwater mussels (Anodonta anatina & Unio mancus), Mytilus edulis L and Green mussel (Perna viridis). Mussels contain high levels of nutrients and bio-actives which were utilized in the form of mussel meals for feed ingredients. The constraint mussels have high heavy metals such as Pb, Hg and Pb. The utilization of mussel meals as a source of protein feed could increase the growth of several types of cultured fish. One alternative used organic acid as a feed additive to reduce toxicity of heavy metals in fish. The conclusion is that mussel meals have the potential as raw material and an alternative protein source to reduce dependence on a fish meal in aquaculture fish feed.
