Serum Biochemistry and Enzymatic Biomaker of Gercacinid Crabs from Mangrove Swamp of the Lagos Lagoon, Nigeria
Summary
This paper is not relevant to microplastics; it measures blood chemistry and enzyme biomarkers in two species of mangrove crabs from the Lagos Lagoon, Nigeria.
Environmental factor is known to influence crab immune chemistry. This study presents the haemato-biochemical parameters and enzymatic biomarker of gercacinid crabs (Cardisoma guanhumi and Cardisoma armatum) from mangrove swamp of the Lagos Lagoon using standard procedure. The haemocyte subpopulations were higher in C. guanhumi than the percentage obtained in C. armatum with no significant difference (P > 0.05). Significantly, higher range values of aspartate aminotransferase (12.03±0.35 µi-1), alanine aminotransferase (10.07±0.58 µi-1), alkaline phosphatase (89.94±3.38 µi-1), lactate dehydrogenase (124.86±0.70 µi-1) and urea (33.90±2.00 mg dL-1) were recorded in C. guanhumi. Examined samples of gercacinid crabs showed significant difference only in malondialdehyde (among the enzymatic biomarkers) with mean values of 6.32±0.05 Hmol/mg pro and 9.36±0.27 Hmol/mg pro for C. guhanhumi and C. armatum respectively. The haemato-biochemical parameters of the gercacinid from the studied location varied across species.

The Ecological Implication of Microplastic in Crabs from a Tropical Lagoon: Ingested Microplastic in Mud Crab Scylla serrata
Researchers examined microplastic ingestion by crabs from a tropical lagoon in West Africa, quantifying particles found in digestive tissues and assessing ecological implications for the local ecosystem. Widespread microplastic ingestion was documented across crab species and size classes.
Fiddler crabs (Tubuca arcuata) as bioindicators of microplastic pollution in mangrove sediments
Researchers used fiddler crabs as bioindicators of microplastic pollution in mangrove sediments, finding that crab tissue microplastic loads correlated with sediment contamination levels and reflected spatial differences in pollution across mangrove sites.
Hemato-biochemical Profiling of a Burrowing Crab Exposed to Polystyrene Microplastic Contaminant
Researchers evaluated the hemato-biochemical effects of polystyrene microplastic exposure on the burrowing crab Cardiosoma guanhumi from Lagos Lagoon mangroves, finding significant reductions in total haemocyte count and altered haemocyte sub-populations compared to unexposed control crabs.
Impact of mangrove restoration on microplastic bioaccumulation in fiddler crabs across degraded, restored, and natural ecosystems
Researchers compared microplastic accumulation in fiddler crabs across degraded, restored, and natural mangrove ecosystems in the Southern Gulf of Mexico. They found that mangrove restoration influenced the amount and types of microplastics that accumulated in the crabs and surrounding sediment. The study suggests that restoring mangrove habitats may help reduce microplastic exposure for the organisms living within them.
Synergistic effects of microplastic and lead trigger physiological and biochemical impairment in a mangrove crab
Researchers exposed mangrove fiddler crabs to microplastics and lead, both alone and in combination, to assess their joint toxic effects. They found that co-exposure synergistically increased lead bioaccumulation, oxygen consumption, and lipid peroxidation while suppressing antioxidant enzyme activity. The study suggests that microplastics can amplify the physiological harm of heavy metal contamination in sensitive mangrove ecosystems.
