“…It has been proven that substances appear in their intestine very quickly after ingestion. Lotocka ( 2001 ) reported that the intestine fills within 30 min after ingestion of food under optimal conditions (Lotocka 2001 ). L. stagnalis , on the other hand, is a grazing organism, which takes up food with its radula.…”

Freshwater organisms are suitable models to study the fate of environmental pollutants. Due to their versatile and everyday use, many environmental pollutants such as triclocarban (TCC) or multi-walled carbon nanotubes (MWCNTs) enter environmental compartments very easily. TCC is known as a disinfectant and is declared as a highly aquatic toxicant. Multi-walled carbon nanotubes are used, e.g., in the automotive industry to improve plastic properties. Both TCCs and MWCNTs can pose major pollution hazards to various organisms. In addition, these substances can bind to each other due to their tendency to interact via strong hydrophobic interactions. Therefore, a short-term test was conducted to investigate the effects of the individual chemicals TCC and weathered MWCNTs (wMWCNTs) on a benthic biofilm and a grazing organism, Lymnaea stagnalis. Furthermore, the two compounds were coupled by an adsorption experiment resulting in a coupled complex formation (TCC + wMWCNTs). L. stagnalis showed no effects in terms of mortality. For benthic biofilm, the coupling test (TCC + wMWCNTs) showed a decrease of 58% in chlorophyll a (Chl-a) concentration. The main effect could be attributed to the wMWCNTs’ exposure alone (decrease of 82%), but not to presence of TCC. The concentration range of Chl-a upon TCC exposure alone was comparable to that in the control group (32 and 37 µg/cm2). With respect to the particulate organic carbon (POC) concentration, very similar results were found for the solvent control, the TCC, and also for the TCC + wMWCNTs group (3, 2.9, and 2.9 mg/cm2). In contrast to the control, a significant increase in POC concentration (100%) was observed for wMWCNTs, but no synergistic effect of TCC + wMWCNTs was detected.

“…Cladocerans constitute over 620 different species and generally fall in the size ranges of 0.2-18 mm [18]. Daphnia magna (small, 1.4 mm), (medium, 2.5 mm), and (large, 3.1 mm), Daphnia pulex (2-3 mm), and Ceriodaphnia dubia (<1.4 mm) [19,20]. While, the average length of shrimp larvae size was 0.65 mm, and the body length of the females reached 2.37 mm at maturity [21].…”

The importance of live feed as a beginning diet in marine shrimp (Penaeus sp.) is largely dependent on careful management during the early stages of larval growth. The COVID-19 pandemic has a significant impact on Malaysian aquaculture, which is critical for seafood supply and security. Cladocerans are an alternative live feed species that outperform Artemia nauplii in terms of nutritional value, economic value, availability, and reproduction rate. In terms of supplying live feed for commercial aquaculture, cladoceran culture and cultivation can therefore be an economically viable, sustainable, and desirable live feed species. The purpose of this study is to collect information on low-cost live feed for marine shrimp used in aquaculture and how COVID-19 affects the sector. Thus, a survey was conducted at a private hatchery and farm in Pekan and Badong, Pahang, Malaysia to investigate the importance of low-cost live feed culture technology to the marine shrimp industry during COVID-19. A total of 20 respondents took part in the survey. During the COVID-19 period in Malaysia, data were gathered using a questionnaire that was planned to be completed via an online form from August 2020 through December 2020. The software utilised was a Google application (Google Form). The data gathered revealed the importance of utilising live feed for maintaining shrimp larvae production in the sector. The current data are critical for developing policy actions to support seafood industries affected by the pandemic at both the national and international levels.
