“…The content of carrageenan and gel strength decreased significantly when the symptoms of ice-ice disease began to appear in the thallus, and decreased with time and the level of thallus damage. The decrease in carrageenan content is directly proportional to the time of bacterial infection (Riyaz et al, 2020).…”

al conocimiento de este grupo en la región. Métodos: Los muestreos se realizaron empleando diversas artes de pesca, en los principales ríos y tributarios que se encuentran en el municipio. Resultados: Se recolectaron 2,430 peces, correspondientes a 38 especies, agrupadas en 31 géneros, 19 familias y 12 órdenes. Las familias con la mayor riqueza específica fueron Cichlidae y Poeciliidae con nueve y seis especies. Priapella intermedia fue la especie más abundante (30.1% del total), seguida por Astyanax finitimus (13.3%) y Pseudoxiphophorus bimaculatus (10.3%). Con respecto a los aspectos biogeográficos del conjunto íctico, se observó un predominio de especies neotropicales (91.9%), dos especies de origen neártico (Ictalurus meridionalis e Ictiobus meridionalis) y cuatro vicarias (Atherinella sallei, Cathorops cf. kailolae, Eugerres mexicanus y Strongylura hubbsi), 31 especies se encuentran evaluadas en alguna categoría de riesgo y dos son exóticas. Conclusiones: La ictiofauna de Santa María Chimalapa es similar al de los cuerpos acuáticos presentes en selvas del sur de México. Son necesarios estudios ecológicos, de conservación e impacto antropogénico para establecer estrategias sustentables de conservación.

“…Early reports describe 'powdery' growth on the thalli prior to the loss of pigmentation 40,41 which is not reported elsewhere. Similarly, some descriptions mention the appearance of a 'moist organic substance', 'slime' or 'mucus' on affected thalli, 34,39,42 which does not appear to be common. Importantly, an accurate and unified description for IID has not been produced to date.…”

“…Hardening of affected tissue is infrequently reported and is also followed by breakage of affected thalli when observed. 39 There is also variation in descriptions of the appearance of affected tissues.

“…Only two other studies have attempted 16S sequencing for the molecular characterization of taxa isolated from IID-affected seaweeds. 39,78 In most cases, the seaweed-derived bacterial sequences are 95-98% identical to the closest characterized matches in publicly available sequence databases and therefore likely not the same species. As such, the exact identity of these isolates remains undetermined.…”

Diseases and pests are major limiting factors to aquaculture production, 1 including seaweeds, 2 prompting global action to improve biosecurity and knowledge of important yield-limiting pathogens affecting sustainable production, both now and in the future. 3,4 Seaweeds comprise almost 30% of global aquaculture production by volume. 5 Production of the carrageenophyte red algal genera Kappaphycus and Eucheuma (collectively known as eucheumatoids) has increased rapidly in the past decade, accounting for 33.99% of global aquatic plant cultivation in 2018. 5 Eucheumatoids are commercially cultivated for production of carrageenans, polysaccharides widely used in the pharmaceutical, cosmetic and food industries.Much of this cultivation occurs in South-East Asia, particularly

“…Similarly, the ability of Pseudoalteromonas carrageenovora to produce kappa-carrageenase enzyme and degrade kappacarrageenan in K. alvarezii indicated that this bacteria could trigger ice-ice disease symptoms like whitening of the thalli (Riyaz et al, 2020).…”

Kappaphycus spp. and Eucheuma spp. are two economically significant seaweed species cultivated globally due to their carrageenan content with numerous commercial applications. They are mainly cultivated in the Philippines, Indonesia, Malaysia, and Tanzania. The culture of these seaweeds also provides income sources for many coastal dwellers. In 2018, the total global production from these seaweeds was about 11 million tonnes. One of the primary problems that affect seaweed production is the incidence of iceice disease. In this article, we reviewed the reported scientific journals on the ice-ice disease of two commercially cultured seaweed species (Kappaphycus spp. and Eucheuma spp.), focusing mainly on causes, occurrence, and control measures. The ice-ice disease is caused by both abiotic and biotic factors manifested by the presence of white and soft parts in the infected seaweeds. The occurrence of this disease varies from species, places, and seasons. Control measures may include proper farm management, polyculture with other seaweeds, pre-soaking with antibacterial substances and nutrient enrichment before out-planting, and possibly using genetic engineering.
