“…The total serum protein recorded in the present study were relatively higher in the exposed crabs compared to the control and this could be as a result of the increased haemocyanin levels as which constitutes about 90% of total protein in crustacean haemolymph (Matozzo and Martin, 2010). This was similar to the findings reported by Davies et al (2015) where loads of Nicothoe astaci copepods in the gills of Homarus gammarus lobster were associated with elevated haemolymph total protein and haemocyanin levels.…”

The study evaluated the effect of polystyrene microplastic contaminant on hemato-biochemical parameters of Cardiosoma guanhumi from the mangrove area of Lagos Lagoon using standard methods. Total Haemocyte Count (THC) ranged between 3050.00±0.00 mL and 4200.00 ±0.05 mL with control crabs having the highest value of 4200.00±0.05 mL. There was significant difference between the treatment groups and the control (p<0.05). Hemocyte sub-population variables showed that crabs fed the control and 0.01g polystyrene microplastic diets had higher granulocyte and monocyte populations but a decrease in agranulocytes. The crabs fed with the polystyrene microplastic contaminated diets were significantly higher in serum protein (32.50±0.05-32.90±0.10 gL-1) than the crab fed with control diet (20.09±0.05 gL-1). Crabs fed 0.01g and 0.02g polystyrene microplastic based diets recorded the same aspartate aminotransferase mean value (19.30 µI-1) which was significantly higher than the mean value (11.50 µI-1) recorded in crabs fed control diet. Crab fed 0.01g polystyrene microplastic based diet recorded most of the highest values for biochemical parameters: Alanine aminotransferase (13.00±0.05 µI-1), alkaline phosphatase (113.70±0.10 µI-1), lactate dehydrogenase (148.60±0.05 µI-1) and urea (40.41 ±0.15 µI-1). The changes in the crabs’ hematological and serum biochemical profiles in this study provide reliable and discriminatory data on the effect of microplastic contaminant calling for long-term monitoring to assess the eco-health of the mangrove system.

“…The potential effects of C. solearis on P. argus also merit investigation. For example, from a pathological viewpoint, histology could identify some immune reactions visually, whereas from a physiological angle, biochemical assays (e.g., Davies et al 2015) could shed more light on this issue; however, molecular diagnostics would be needed to observe transcriptomic changes to get a full assessment of immunological effects.…”

Untangling the effects of size, habitat and invertebrate biodiversity on parasite prevalence in the Caribbean spiny lobster

The spiny lobster Panulirus argus is an important benthic mesopredator and a major fishing resource across the Wider Caribbean region. This species is host to the pathogenic virus PaV1 and metacercariae of Cymatocarpus solearis, a digenean trematode whose first intermediate host remains unknown. Previous studies found that the probability of infection with PaV1 was higher in juvenile lobsters and in densely vegetated habitats (suggesting that marine vegetation can be an environmental reservoir for PaV1), whereas the probability of infection with C. solearis was higher for larger lobsters and in poorly vegetated habitats. To increase insight into the role of habitat and body size in the ecology of lobster diseases, the presence of both C. solearis and PaV1 in P. argus was investigated across three contrasting zones in Bahía de la Ascensión, Mexico (19°35′27″N, 87°38′06″W): reef, lagoon and shallow habitat. Additionally, habitat complexity, cover of benthic components, and macroinvertebrate biodiversity were characterized in each zone. Consistent with previous studies, probability of infection with PaV1 (both at a clinical and infective level) decreased with increasing lobster size and was highest in the seagrass-rich lagoon, supporting the idea that marine vegetation could be an environmental reservoir for PaV1. In contrast, the probability of infection with C. solearis increased significantly with lobster size but did not vary with zone, suggesting no relationship with benthic substrate type. However, based on results of macroinvertebrate diversity, the gastropods Cerithium litteratum and Tegula fasciata are put forward as potential candidates for the first intermediate hosts of C. solearis.

The common technique of traditional salt production in Indonesia is seawater evaporation technology, which uses sunlight to produce salt crystals from seawater. However, in general, the applied technology only produces salt with about 80% NaCl and water contents >7%, impurities >2%, and other contaminants. This produced salt is not suitable to be used as industrial salt. This study aimed to determine the effects of liquid organic fertilizer Gracilaria sp. addition into the culture media of Tetraselmis chuii on Artemia sp. growth, to identify the profile of length, weight, and survival rate of Artemia sp., and finally attempted to uncover the contribution of Artemia sp. in impurity mineral absorption and NaCl content improvement. The results of the study showed that the density of T. chuii based on the concentration of liquid organic fertilizer Gracilaria sp. was significantly different (p<0.05) in each treatment. T. chuii cultivation using liquid organic fertilizer Gracilaria sp. 16 mg N/mL resulted in the highest density on the culture days. However, the studies showed that there was no significant effect (p>0.05) on the weight and length gain of Artemia sp. The research conducted can support the downstream use of products from engineering research in the field of technology to increase the added value of salt products and be part of the contribution to the achievement of the 14th SDG on life below water. Highlight Research Integration of chuii and Artemia sp. culture in salt production could improve NaCl contents by up to 97% and reduced impurities of sulfate and magnesium. The result of the first phase of this study is the density of chuii. This finding is useful to find out the effects of Gracilaria sp. liquid organic fertilizer administration as a source of nitrogen that improves the growth of T. chuii. The highest density of T. chuii resulted from a treatment receiving the dose of 16 N mg/L Gracilaria sp. liquid organic fertilizer with > 5 x 106 cells/mL. This finding indicates that the administration of 16 N mg/L Gracilaria liquid organic fertilizer into the culture medium provided a source of nitrogen and phosphorus for the metabolism of T. chuii. The results of the mineral content test on Artemia sp. show the largest percentage change in Mg2+ > SO42- > Cl- > Na+. The densities of Artemia sp. showed a positive trend of increasing levels of Mg2+ and SO42-, which coincided with decreasing levels of Mg2+ and SO42- in seawater media. The results of NaCl content measurement in water with Artemia sp. culture integration show salt with excellent quality of 97% that met the criteria of industrial salt. The contribution of Artemia sp. to improving the quality of salt products is interesting and has the potential to serve as an alternative to the traditional salt-farming system that is currently practiced.
