“…Specimens of mullet, Mugil platanus, from Cananéia, São Paulo State, Brazil, have been previously studied by Ranzani-Paiva & Ishikawa (1996) and Ranzani-Paiva et al (1997). Using the allometric condition factor (K) these authors did not detect any effect of parasitism on state of mullet health.…”

This study involved 334 specimens of mullet, Mugil platanus, captured monthly in the estuarine region of Cananéia, São Paulo State, Brazil, from July 1988 to June 1989, and examined for the presence of gill parasites. Parasitological inspections revealed the occurrence of the following groups: Trichodina sp., Monogenoidea, Copepoda, and Hirudinea. Only four mullets were not parasitized. Total weight and total length of all 334 mullet specimens examined were used for adjusting the weight-length relationship curve and calculating the relative condition factor (Kn). The 118 specimens infested with monogenoideans on average had lower weights than expected (Kn < 1.0), and the 81 fish co-infested with Copepoda, Monogenoidea, and Trichodina sp. showed a Kn < 1.0. The other infested and non-infested mullets had a Kn > 1.0. It was possible to infer that gill infestation with monogenoideans alters mullet weight, especially in the presence of co-infestation with Trichodina sp. and copepods.

“…Other studies showing haematologic changes with age or size in fish species on the tainha ( Mugil platanus ) found that mean values for Ht, Hb, MCV, MCH and MCHC showed a slight increase as individuals became larger (Hilge, 1980). Bigger fish present higher mean values for MCV, MCH and MCHC for dourado ( Salminus maxillosus ) (Ranzani‐Paiva, 1995). Previous studies carried out with carp ( Cyprinus carpio , Baghizadeh & Khara, 2015) and Caspian salmon ( Salmo trutta caspius , Jamalzadeh & Ghomi, 2009) showed significant differences in RBC, WBC, MCV, MCH, MCHC, haemoglobin and monocyte among fish from different ages.…”

Striped bass (Morone saxatilis) is a species with high production potential for human consumption. However, like any other cultured species, they are prone to be exposed to adverse climate conditions, compromising their health status until a certain degree compromises the success of reaching commercial size. It is proposed that haematological parameters testing during the whole growing out season represents a useful tool to assess the overall fish health status. Information on M. saxatilis haematology is limited. Therefore, the present study aimed was to provide the haematological and blood chemistry values for commercial striped bass grow‐out. Fish from three different group sizes and under low sub‐optimal temperature (16 to 18°C) were sampled in correlation to copepods (Peniculus sp.) present attached to the fins. Thirty fish from each group (sized 0.17, 0.54 and 1.17 kg, corresponding to different ages and batches) were all sampled (blood and external parasites count) during the spring (5 June, June 12 and June 16, 2019). The results show that differences in blood parameters were only observed according to the weight of striped bass such as the haematocrit (HCT), haemoglobin, mean corpuscular haemoglobin concentration (MCHC), white blood cells (WBC) count, total protein, globulin, ratio A/G, cholesterol, triglycerides and glucose. In contrast, the copepods present showed a preference for the caudal fin of the striped bass, followed by the first dorsal and pectoral fin. The smaller fish (0.179 kg) were the most susceptible to Peniculus sp., compared to the largest fish (1.174 kg). So far, it can be concluded that at this stage, the copepod does not show any adverse effect on the fish health since the condition factor and blood parameters were statistically similar along with the different copepod infestation levels (intensity ranged from 7 to 109). However, this new copepod, here registered for the first time in the Morone saxatilis, was registered during the sunset to increase environmental temperature. Even if no signs of a harmful relationship between parasites between young and old organisms, it will be necessary to be further monitored. The copepod incidence and the blood parameters should be analysed along the year (different temperatures), aiming to detect any correlation to the copepods present or, in any case, the overall health status or another parasite present under the seabass culture conditions.

“…To determine the normal hematological parameters in fresh-water teleosts, heparin has been the most frequently anticoagulant used by researchers such as Martins and Pitombeira (1968), Ranzani-Paiva and Godinho (1983), Zuim et al (1984), Ranzani-Paiva and Godinho (1985), Zuim et al (1986), Satake et al (1986Satake et al ( , 1991, Ranzani-Paiva (1991), Borghi and Silva-Souza (1992), Wepener et al (1992), Wilhelm-Filho et al (1992), Shiau et al (1993), Martínez et al (1994), Martins et al (1995) and Ranzani-Paiva and Ishikawa (1996). It has also been used in hematological variation studies in parasited fish (Ranzani-Paiva et al, 1987).…”
