“…Carrageenan is extracted from red seaweeds. Several groups of red algae show superior concentrations of one particular group and thus are known as carrageenophytes (carrageenan-producers), with most families belonging to the Gigartinales [ 195 , 196 ]. Several commercial red seaweed species supply a sub-family of carrageenan extracts.…”

Seaweeds (marine macroalgae) are autotrophic organisms capable of producing many compounds of interest. For a long time, seaweeds have been seen as a great nutritional resource, primarily in Asian countries to later gain importance in Europe and South America, as well as in North America and Australia. It has been reported that edible seaweeds are rich in proteins, lipids and dietary fibers. Moreover, they have plenty of bioactive molecules that can be applied in nutraceutical, pharmaceutical and cosmetic areas. There are historical registers of harvest and cultivation of seaweeds but with the increment of the studies of seaweeds and their valuable compounds, their aquaculture has increased. The methodology of cultivation varies from onshore to offshore. Seaweeds can also be part of integrated multi-trophic aquaculture (IMTA), which has great opportunities but is also very challenging to the farmers. This multidisciplinary field applied to the seaweed aquaculture is very promising to improve the methods and techniques; this area is developed under the denominated industry 4.0.

“…Besides the peaks of the type I β cellulose, the presence of a crystallographic plane in 2θ ¼ 17.65 with higher intensity was also noticed for the fabrics modified with PAni Leucoemeraldine base and Pernigraniline base. The presence of this peak with higher intensity is attributed to the alteration of cellulose from type I to type III, which took place due to the presence of amines, [67] such as phenylhydrazine and nitric acid, used to the treatment of the fabrics.…”

In this work, intelligent materials were developed from the cotton fabric modified with polyaniline (PAni). PAni was used in different oxidation states (Emeraldine Salt, Emeraldine, Leucoemeraldine and Pernigraniline Base). The obtained materials were tested as colorimetric hydrogen sulfide gas sensors. The intelligent fabrics were analyzed by Infrared Spectrometry (FTIR), X‐ray powder diffraction (XRD), Thermogravimetric Analysis (TGA), Energy Dispersive X‐Ray Spectroscopy (EDS), Optical Microscopy and Electrical Resistivity Analysis. Smart fabrics were exposed to hydrogen sulfide gas, and colorimetric analyses were performed before and after exposure to identify fabrics capacity of detection. The obtained results allowed inferring that the best material was the one modified with Emeraldine base. This low‐cost material can be easily obtained, constituting a valuable hydrogen sulfide gas detection tool.

“…Due to the impacts associated with nuisance algal blooms on the fishery, water quality, and human, rapid assessment is inevitable. Red algae are a widespread group of uni-to-multicellular aquatic photoautotrophs, of which about 98% are marine, and 2% are freshwater (Deluquei & Lopez-Bailtista, 2007).…”

“…In Tanzania, studies on red algae have been reported interchangeably (seaweeds and algae) in marine or coastal ecology (Msuya & Neori, 2002;Buriyo et al, 2004;Msuya, Kyewalyanga, & Salum, 2006;Troell et al, 2011). The social-economic potentials of the industry have led Tanzania to be among the group of leading carrageenan-producing (food derived from red algae or seaweeds) in the tropical area along with the Philippines and Indonesia (Deluquei & Lopez-Bailtista, 2007).…”

The Unusual Reddish-Bloom Appearance in a Freshwater Fishpond at Kingolwira National Fish Farming Center, Morogoro, Tanzania

The study aimed to examines a case of what constituted the uncommonly reddish-bloom appearance in the fishponds during the dry season (September 2018) at Kingolwira National Fish Farming Center located in Morogoro, Tanzania. The study used a benchtop FlowCAM® to investigate species' morphology. One-time assessment of physico-chemical characteristics during the event was performed from the reddish and non-reddish fishponds. Images were compared with the available literature, but also t-test statistics were performed to examine the difference between the fishponds. The results show that the fishponds were significantly (p<0.05) different from each other in terms of physico-chemical parameters except for water temperatures. Furthermore, Microcystis species dominated the non-reddish fishpond whereas Euglenophytes species were pervasive in the reddish fishpond. The two species have the potential to produce secondary metabolites (toxins) or to produce a hypoxia condition that is harmful to the fishery, aquatic ecology, and human. To confirm toxicity nature and dynamics further, future studies should consider extensive and regular diurnal and long-term monitoring.
