    Marine litter is a key vector of dispersing invasive species in the marine environment. However, our knowledge of the ecological interactions between these species and litter is still incomplete. Here, we investigated the substrate preferences and physical characteristics of marine litter colonized by the invasive mussel Mytella strigata, and explored the role of litter in the population expansion of this species along the Tamil Nadu coast, India. A total of 72 fouled debris were observed along the study areas. The majority of the fouling litter was composed of plastic (87.5 %), followed by rubber (4.2 %), wood (4.2 %), glass (2.8 %) and metal (1.4 %). A total of 2637 individuals of M. strigata were recorded on the marine litter, with recruitment on plastic substrates. Particularly, M. strigata were most common on large marine litter with irregular or cylindrical shapes, rough surfaces and transparent, blue or green colours. Our work provides evidence that marine litter can play a role in the reproduction of this invasive mussel. Consequently, M. strigata benefits from the litter substrates and the habitat complexity created by anthropogenic materials along the Tamil Nadu coast, enhancing its survival and reproduction. This could promote the expansion of the M. strigata population and thus affect the composition and structure of the marine ecosystem.

    The purpose of this review is to reveal the lipid and protein contents in black soldier fly larvae (BSFL) for the sustainable production of protein and energy sources. It has been observed from studies in the literature that the larval lipid and protein contents vary with the rearing conditions as well as the downstream processing employed. The homogenous, heterogenous and microbial-treated substrates via fermentation are used to rear BSFL and are compared in this review for the simultaneous production of larval protein and biodiesel. Moreover, the best moisture content and the aeration rate of larval feeding substrates are also reported in this review to enhance the growth of BSFL. As the downstream process after harvesting starts with larval inactivation, various related methods have also been reviewed in relation to its impact on the quality/quantity of larval protein and lipids. Subsequently, the other downstream processes, namely, extraction and transesterification to biodiesel, are finally epitomized from the literature to provide a comprehensive review for the production of unconventional protein and lipid sources from BSFL feedstock. Incontrovertibly, the review accentuates the great potential use of BSFL biomass as a green source of protein and lipids for energy production in the form of biodiesel. The traditional protein and energy sources, preponderantly fishmeal, are unsustainable naturally, pressingly calling for immediate substitutions to cater for the rising demands. Accordingly, this review stresses the benefits of using BSFL biomass in detailing its production from upstream all the way to downstream processes which are green and economical at the same time.
