“…Water conditions can, and most probably will, adversely change during fish transport. Fish transport is a global necessity, related to several activities/goals: (i) human feeding (Marc ßalo et al 2008;Reglero et al 2013); (ii) transport of fry from hatchery sites to growth/fattening ponds (Abreu et al 2008) or for human recreation fishing (angling); and (iii) transport of wild animals for aquaculture facilities (Marc ßalo et al 2008;Oyoo-Okoth et al 2011), release of juveniles for stocking programmes (Iversen et al 1998;Gomes et al 2003), for public aquaria Harmon 2009), for ornamental (Wright et al 2007;Gomes et al 2009;Brinn et al 2012), or even for research (Corrêa et al 2014). Stress can lead to infectious diseases or even cause animal mortality (Bernoth and Crane 1995;Murphy and Lewbart 1995).…”

An overview of stress physiology of fish transport: changes in water quality as a function of transport duration

This study brings an integrated analysis about the relationship between water deterioration and its physiological consequences in live fish transport. The analysis was focused on the transport water and its deterioration, and physiological challenges imposed on the fish. Usual commercial handling procedures employed to mitigate fish stress during transport were discussed. Future topics of research for the establishment of safer fish transport protocols were proposed. Transport was classified into short (≤8 h) or long transport (>8 h). The main issue in short transports should be the prevention of water pH reduction, while in long transports it is the increase in ammonia. Plasma cortisol is the most employed marker for stress and is acutely elevated upon short episodes of transport, but remains elevated even in long‐transport events. Plasma glucose is perhaps a better marker for handling stress. Plasma lactate, pH, osmolality CO2 and ions should be more often evaluated. Plasma Na+ and Cl‐ are very useful markers of acidosis, due to their respective exchange for H+ and HCO3−, for acid–base regulation. The establishment of species‐specific transport protocols should be preceded by such combined analyses of water and physiological parameters.

“…Coming from the Amazon, Orinoco, and Tocantins-Araguaia River basins, this species has spread out over the Southeast region of Brazil due to its high growth rate, good performance, and exquisite flesh (Arbeláez-Rojas & Moraes, 2010;Cruz-Casallas et al, 2011). It is also tolerant to transport, handling, and crowding (Abreu et al, 2008). Owing to its rheophilic habit, the species is able to swim for long distances to reproduce, besides being streamlined and fusiform, which has motivated its use in trials on the performance of fish subjected to sustained swimming (Arbeláez-Rojas & Moraes, 2010).…”

-The objective of this work was to evaluate the effect of stocking density associated with the swimming exercise on the stress responses of Brycon amazonicus. During 70 days, fish were subjected to three stocking densities: LD, low density of 88 fish per cubic meter; ID, intermediary density of 176 fish per cubic meter; and HD, high density of 353 fish per cubic meter. These densities were combined with static water (non-exercised group) or moderate-speed water (exercised group). Chronic stress was observed in HD, and plasma cortisol and glucose increased with the stocking densities. In HD, levels of plasma cortisol were significantly lower in exercised fish (135 ng mL ). The greatest hepatic glycogen bulks occurred in fish kept in ID and sustained swimming. Hepatic free amino acids (FAA) increased with the stocking density, particularly in non-exercised fish. The contents of FAA in the liver and of free fatty acids (FFA) in the liver and muscle were mobilized to meet the metabolic demands imposed by exercise and stocking density. The hematological parameters remained stable. The results show that Brycon amazonicus is more resistant to stress when subjected to sustained swimming and high stocking density than to static water. ). Os maiores acúmulos de glicogênio hepático ocorreram em peixes mantidos em DI e em natação sustentada. Os aminoácidos livres (AAL) hepáticos aumentaram com a densidade de estocagem, particularmente nos peixes não exercitados. As reservas de AAL hepáticos e de ácidos graxos livres hepáticos e musculares foram mobilizados para atender às demandas metabólicas impostas pelo exercício e pela densidade de estocagem. Os parâmetros hematológicos mantiveram-se estáveis. Os resultados são indicativos de que o matrinxã é mais resistente ao estresse quando submetido à natação sustentada e à alta densidade de estocagem que à água parada.Termos para indexação: bem-estar animal, piscicultura intensiva, respostas metabólicas, exercício físico.

“…Hari ke-6, kadar glukosa hemolymph secara signifikan tinggi pada lobster yang dipelihara pada perlakuan K dan F. Hal ini diduga karena pada pelakuan K dan F lobster mengalami stres. Peningkatan glukosa darah (hyperglycemia) menunjukkan ikan mengalami stres (Hastuti et al, 2003); (Lorenzon et al, 2008); (Abreu et al, 2008); (Supriyono et al, 2010). Menurut Hastuti et al (2003), mekanisme terjadinya hyperglycemia adalah sebagai berikut: pemecahan glikogen hati dan otot melalui jalur glikogenolisis yang menghasilkan glukosa dan merupakan efek metabolisme katekolamin, pemecahan protein dan lipid melalui jalur glukoneogenesis yang merupakan efek metabolisme kortisol, inaktifasi insulin sebagai efek metabolisme hormon stres sehingga menutup penggunaan glukosa oleh sel.…”

The problems in culture of early juvenile phase of spiny lobster Panulirus homarus is low survival rate of the seed. One of strategies to improve production is using filtration system during nursery of spiny lobster. ABSTRAKPermasalahan dalam budidaya lobster pasir Panulirus homarus yaitu rendahnya tingkat kelangsungan hidup pada fase juvenil tahap awal. Salah satu solusi untuk meningkatkan produksi adalah dengan menggunakan sistem filtrasi fisik selama pendedran lobster. Tujuan penelitian ini untuk mengevaluasi perbedaan sistem filtrasi fisik terhadap respons stres dan tingkat kelangsungan hidup juvenil P. homarus. Penelitian ini terdiri dari empat perlakuan dan dua ulangan. Perlakuan menggunakan sistem aliran kontinyu tanpa protein skimmer dan top filter (kontrol), sistem filtrasi fisik dengan protein skimmer (SK), sistem filtrasi fisik dengan top filter (F) dan sistem filtrasi fisik dengan kombinasi protein skimmer dan top filter (SKF). Bobot awal P. homarus sebesar 0,18±0,01 g dipelihara selama 60 hari dengan kepadatan 250 ekor / bak. Selama pemeliharaan, P. homarus diberi pakan ikan rucah sebanyak 20% dari bobot. Parameter uji untuk respons stres yaitu glukosa hemolymph dianalisis pada hari 0, 6, 20 dan 60. Parameter tingkat kelangsungan hidup diamati pada akhir penelitian. Hasil penelitian menunjukkan bahwa perlakuan sistem filtrasi fisik dengan mengunakan kombinasi protein skimmer dan top filter (SKF) mampu menurunkan respons stres dengan menurunkan glukosa hemolymph pada juvenil P. homarus selama pemeliharaan. Tingkat kelangsungan hidup juga lebih tinggi (P <0,05) pada perlakuan SKF (33,2%) dibandingkan perlakuan lainnya. Dapat disimpulkan bahwa SKF adalah sistem filtrasi fisik terbaik untuk pendederan juvenil lobster pasir P. homarus.Kata kunci: glukosa hemolymph, lobster pasir, sistem filtrasi, tingkat kelangsungan hidup
