“…A putative toxic effect is further supported by the total platelet count that was lower in fish fed Catarina scallop viscera diet, and which indicates this fish might have slower coagulation times; they also had lower levels of haemoglobin and haematocrit. This is contrast to results of Del Rio‐Zaragoza, Fajer‐Ávila, Almazán‐Rueda, and Abdo de la Parra () who found that infected snapper had higher levels of haematocrit (63% in infected vs. 52% in healthy snappers) and white cells, but slower coagulation time in infected snappers. Higher haematocrit levels can also be found in fish with stronger locomotor activity (Wintrobe, ), while starvation can reduce the levels of haematocrit (De Pedro, Guijarro, López‐Patiño, Martínez‐Álvarez, & Delgado, ); usually, haematocrit levels around 50% are indicator of good health (Wilhelm Filho et al., ).…”

A 60‐day feeding trial to determine the nutritional value of marine by‐product meals in diets for longfin yellowtail Seriola rivoliana juveniles (48.1 ± 0.6 g initial weight) was conducted. Five diets were evaluated: a reference diet (RD; 500 g kg−1 CP, 130 g kg−1 L), containing 500 g kg−1 of fish meal (FM); three experimental diets with 125 g kg−1 of shrimp head (SM), Catarina scallop viscera (CM) or Pen shell viscera (PM) meals; and one diet (SCP) containing 125 g kg−1 of each of the experimental meals, to partially replace FM. Survival was not significantly affected by any treatment. Individual weight gain per day was high for the PM (5.3 ± 0.51 g d−1) and SM (4.7 ± 0.32 g d−1) diets, being significantly higher than the RD (3.5 ± 0.23 g d−1) and the other treatments (<1.2 g d−1). Feed intake was high in PM and SM diets, and very low in SCP and CM diets. Biochemical and haematological parameters were similar among treatments RD, PM and SM, while fish fed CM and SCP exhibited lower levels of total protein, cholesterol, haematocrit and haemoglobin. The results indicate that SM or PM can be used to partially replace FM in diets for yellowtail juveniles.

“…In particular, high hemoglobin and red blood cell counts can serve to indicate good health (Zhou et al, 2005). In the present study, the blood parameter values of fish receiving the different diets indicated that the condition and health status were considered normal for fish fed food-grade PBM diets (Del Rio-Zaragoza et al, 2011). This study showed that the body composition of the snapper was not affected by the replacement of fish meal with PBM meals.…”

ABSTRACT. The feasibility of replacing fish meal protein at different levels with poultry by product meal food grade (PBM-FG) was assessed in diets for spotted rose snapper Lutjanus guttatus. Four diets were formulated, the control diet fish meal was used as the main protein source (FM); the other three diets had increasing levels of PBM-FG replacing 25, 50 or 75% of the fish meal protein respectively. The diets were fed close to apparent satiation, three times a day to quadruplicate groups of juvenile snapper (average body weight 11.0 ± 0.04 g). The fish were randomly distributed into groups of 15 fish in a 120 L seawater tank. The response of snapper to diets containing graded levels of fish meal was evaluated by measuring weight gain, feed efficiency, body composition, hematological parameters and apparent nutrient digestibility during a 12-week period. The replacing of the 25% of fish meal protein by PBM-FG did show a similar trend for feed efficiency and growth performance than control diet. Feed efficiency and growth performance was reduced at 75% level of fish meal protein replacement by PBM-FG, due to deficiencies of lysine and methionine. The final whole-body proximate composition did not differ among treatments. The hematological characteristics were similar among the treatments control, 25 and 50%, but the fish fed PBM-FG 75% showed the lowest levels for total protein and glucose parameters. The dietary dry matter and protein apparent digestibility coefficients (ADCs) decreased with increasing dietary PBM-FG. High values for lipid ADCs were observed in all diets.

La factibilidad de la sustitución de la proteína de harina de pescado por proteína de ave, grado alimento (PBM-FG), fue evaluada en dietas para pargo lunarejo Lutjanus guttatus. Se formularon cuatro dietas, en la dieta control la harina de pescado (FM) se utilizó como principal fuente de proteína. Las otras tres dietas tenían crecientes niveles de PBM-FG en reemplazo del 25, 50 y 75% de la proteína de FM respectivamente. Las dietas fueron ofrecidas a saciedad aparente, tres veces al día a grupos de cuatro réplicas de juveniles (peso corporal promedio 11,0 ± 0,04 g). Los peces fueron distribuidos aleatoriamente en grupos de 15 peces en estanques de 120 L de agua de mar. La respuesta del pargo a las dietas, contenidas con niveles graduales de harina de pescado, fue evaluada midiendo la ganancia en peso, eficiencia del alimento, composición corporal, parámetros hematológicos y digestibilidad aparente de nutrientes durante un periodo de 12 semanas. El reemplazo del 25% de la proteína de FM por PBM-FG mostró una tendencia similar para la eficiencia del alimento y el desempeño productivo que la dieta control. La eficiencia del alimento y el rendimiento productivo fueron reducidos a un nivel de 75% ...

“…Considering the damage that A. ocellatum can cause in the gills, haematological analysis could represent a good approach for evaluating fish immune responses to a parasite outbreak. Haematological analyses can be used as indicators of fish health, as they can provide information related to fish tolerance to stress, metabolic disorders, reproductive dysfunctions or pathologies, as those associated with parasites (Clauss, Dove & Arnold 2008;Del Rio-Zaragoza, Hernandez-Rodriguez & Buckle-Ramirez 2008;Buscaino et al 2010;Del Rio-Zaragoza et al 2011).

Amyloodiniosis represents a major bottleneck for semi-intensive aquaculture production in Southern Europe, causing extremely high mortalities. Amyloodinium ocellatum is a parasitic dinoflagellate that can infest almost all fish, crustacean and bivalves that live within its ecological range. Fish mortalities are usually attributed to anoxia, associated with serious gill hyperplasia, inflammation, haemorrhage and necrosis in heavy infestations; or with osmoregulatory impairment and secondary microbial infections due to severe epithelial damage in mild infestation. However, physiological information about the host responses to A. ocellatum infestation is scarce. In this work, we analysed the proteome of gilthead sea bream (Sparus aurata) plasma and relate it with haematological and immunological indicators, in order to enlighten the different physiological responses when exposed to an A. ocellatum outbreak. Using 2D-DIGE, immunological and haematological analysis and in response to the A. ocellatum contamination we have identified several proteins associated with acute-phase response, inflammation, lipid transport, homoeostasis, and osmoregulation, wound healing, neoplasia and iron transport. Overall, this preliminary study revealed that amyloodiniosis affects some fish functional pathways as revealed by the changes in the plasma proteome of S. aurata, and that the innate immunological system is not activated in the presence of the parasite.
